Tutorial: Tutorial NETCONF and YANG

Network providers are challenged by new requirements for fast and error-free service turn-up. Existing approaches to configuration management, such as CLI scripting, device-specific adapters, and entrenched commercial tools, are an impediment to meeting these new requirements. Until recently, there has been no standard way of configuring network devices other than SNMP, which is not optimal for configuration management. The IETF has released NETCONF (RFC 6241) and YANG (RFC 6020), which are standards focusing on configuration management. The presentation will give a technical overview of these standards, and will show how NETCONF and YANG address issues around automation and programmability. The tutorial will also contain live demos.

Tutorial: Whiteboarding 101

The “whiteboard talk” represents one of the key ways that engineers can communicate ideas in a concise and educational way to colleagues. More than a classroom lecture or a slide presentation, a whiteboard talk is a combination of several disciplines including teaching, storytelling, and improvisational acting. In this interactive tutorial, the attendees will learn (through discussion and breakout sessions) how to organize a whiteboard discussion, how to avoid popular pitfalls, and how to make sure that their audience walks away with the knowledge that the attendee wants them to have. These topics include how to narrow down the scope of a topic (both in terms of the topic itself and the level of abstraction), how to build the knowledge model for the talk, how to define terms for different audiences, and how to handle difficult audience members.

Tutorial: There Are More Layers Than Just Layer 3...

While IPv6 is a layer 3 protocol, major changes between versions 4 and 6 are affecting networks and applications at much higher in the stack. While it would be nice to fantasize about a world where we, as network architects, could do layer 3 and let someone else deal with other IPv6 implementation issues, we may be the best suited to identify and address these issues. End hosts might be making routing decisions and routing announcements that we don't expect. Learn what the issues are and how to work with system groups to solve these issues.

Tutorial: MPLS OAM

MPLS networks started off to support protocol technologies like ATM, FrameRelay, etc., to be transported over IP core networks in a seamless fashion. This also facilitated in providing various services like VPN, PWE3 etc. In the recent past MPLS protocol evolved as a replacement for traditional TDM transport networks by the way of MPLS-TP. Though the technology is mature at data plane and control plane, the OAM within the protocol could not keep the pace with the rapid developments. This presentation provides detailed OAM techniques to be used within each area of MPLS networks and what tools to be used and some of the benefits which could be realized in managing the service provider networks.

Tutorial: The Service Provider Tool Kit

Top techniques, tools, and approaches that needs to be deployed before the crisis. Don’t wait for a security crisis before deploying the tools you need to protect your backbone, cloud, data center, mobile, or broadband infrastructure. There are proven tools, techniques, and approaches to security that is tuned for “Big Networks.” These tools in a “SP Security Toolkit” have proven to work in some of the biggest networks on the planet. This tutorial will review all these techniques – focusing on the how and why they need to be deployed along with usage examples. The hope is for operators attending the session to consider convincing their management that many of the tools in the toolkit need to be deployed before a crisis – to prepare the network to mitigate risk in the middle of a crisis. This session is an updated session from past SP Security and NSP-SEC Top Ten tutorials. It will be tuned to be a productive review for operators who deploy many of these techniques today while empowering new operators with the knowledge to return and make changes to their network.

Tutorial: Intermediate Perl Scripting for Network Operators

This tutorial, the second in a series, builds on the introduction scripting tutorial by covering more advanced topics and real world coding solutions including database access, network programming, module development and references. While our time is too limited , we will learn about and implement these constructs by example. We will step through the process of creating our own network-based service application that implements modules, communicates with a database, handles command line arguments, writes logs to a syslog server and more. Participants can expect to come away with enough knowledge to start hacking their own advanced applications or make use of the example code provided as a foundation towards something even more useful in their own real networks.

Tutorial: You Can't Do That With nslookup: DNS(SEC) Troubleshooting

Troubleshooting DNS before DNSSEC was hard enough, and it was made more difficult when people tried to troubleshoot complex DNS problems using old tools like nslookup. With DNSSEC, the number and complexity of DNS issues makes it imperative that DNS admins understand how to use the tools available to them. This tutorial explains how to use (and interpret) tools like dig, dnscap, dnsviz, and others. It covers these specific topics (not necessarily in this order or structure): Basic DNS troubleshooting with dig, Visualizing DNSSEC with dnsviz, dnscap and nmsg: Specialized packet capture tools for DNS and what they can do for you, Understanding the troubleshooting process and troubleshooting hard issues.

Tutorial: Introduction to DNSSEC

I propose to teach my approximately one-hour DNSSEC introductory class. This is the same tutorial I taught at NANOG51 in Miami. The class covers the motivation for DNSSEC and an overview of how it works, down to the level of individual DNS resource records. It's comprehensive but not overwhelming: I believe it's very understandable. Students need to know what public/private key cryptography and digital signatures are, or they'll be a bit lost, and a very high level understanding of DNS would be helpful, too (e.g., knowledge of what a zone is). There's probably a nicer-looking abstract than this one already on file from NANOG 51... The tutorial went well last time and I'd enjoy teaching it again.

Tutorial: RBridges and the IETF TRILL Protocol

RBridges, based on the IETF TRILL protocol, provide safe optimal pair-wise forwarding without configuration and support for multipathing of both unicast and multicast traffic. They achieve this with IS-IS routing and encapsulation of traffic with a header that includes a hop count. RBridges are compatible with previous IEEE 802.1 customer bridges, as well as IPv4 and IPv6 routers and end nodes, and such bridges can be incrementally replaced by RBridges. Current work on minimizing broadcast traffic, including ARP/ND optimization, will also be covered.

Tutorial: Introduction to Label switched Multicast: P2MP-TE & mLDP

Service Providers using MPLS infrastructure want to offer Multicast Services to their customers using the same MPLS core network that are used to offer unicast services. One of the widely deployed solutions has been Multicast VPN or mVPN. However, deploying mVPN has always demanded re-engineering their core links to carry PIM traffic. Also, they could not leverage high service availability features of Fast-reroute for multicast traffic passing through MPLS core. <BR><BR> Recently, IETF has come out with two good solutions: P2MP TE and mLDP, in which MPLS technology has been extended to carry Multicast Traffic using labels, known as Label switched Multicast. The solutions have eliminated the need for any PIM configurations within MPLS core and has greatly simplified service/operational maintenance requirements of SP providers. <BR><BR> This tutorial gives an introductory overview of the two new approaches: P2MP TE and mLDP used to carry Multicast Traffic through SP MPLS core. <BR><BR> The following topics will be covered as part of this tutorial: <UL> <LI> Motivation</LI> <LI> Multicast Solutions</LI> <LI> P2MP TE Overview</LI> <LI> mLDP Overview</LI> <LI> P2MP TE Demo</LI> <LI> Q and A</LI> </UL>

You've been using tools like Puppet and cfengine to corral the complexity on your servers. You revel in the scalability, reliability, and ease of maintenance of doing it The Right Way. You don't fear the next change because you know the tools will just get it Right. But you still tremble at an 'enable' prompt, hoping you remembered all the bits that need to be twiddled, on all the networking devices everywhere. Is your DNS tied on straight - both ways? Is it all *really* being monitored by Nagios? As your network's complexity increases, so do the errors, inconsistencies, and omissions caused by manual configuration, and brokenness abounds. But wait - there's a way out of the swamp! Come hear Brent Chapman as he reveals methods and tools for automating the mind-numbing task of configuring network devices and services. Among other things, he'll talk about his cool new open source 'Netomata Config Generator', which addresses some of these problems.

The network capacity purchasing RFP can be a powerful tool that insures all options are on the table during pricing negotiations. It also allows the purchaser to remain firmly in control of the process. We aren't buying used cars, we're subscribing to radically changing costs that need to be managed closely. In this talk we will take a mid level walk through a tested RFP and discuss different aspects of an effective request for pricing or proposal "RFP". We will discuss how defining needs over multiple years can be strategically related to discounts and pricing, how to ask providers to define their own service delivery needs so you can recoup costs and standard terms and conditions to minimize lawyer time and expense. We'll conclude with a walk through of an actual RFP that will be provided as a template for later use.

Tutorial: VoIP Peering

While various forms of application-layer peering overlays have long existed on the Internet to support applications like email and newsgroups, Voice over IP (VoIP) peering brings with it a new set of elements, policies, and challenges. This tutorial begins with the fundamentals, exploring why peering is even necessary for a largely client-driven application like VoIP. It then surveys the functional elements necessary to peer between telephony-replacing deployments, using the ongoing IETF work on VoIP peering as a touchstone. All of this is considered with a mind to the ongoing evolution of traditional voice services, including mobile telephony, and the rise of other client-driven Internet applications including instant messaging and peer-to-peer file sharing.

Tutorial: A Load-Sharing Approach to Increase Capacity in IP/MPLS Networks

Currently, network operators are increasingly bundling multiple links together to meet the growing demand for IP and MPLS services. They also use several Equal Cost Multi-Path techniques at various protocol layers such as BGP, OSPF, ISIS, RSVP-TE and LDP to provide multiple paths. This leads to numerous combinations of load balanced paths at different layers (IP, MPLS, Ethernet). With services being offered for native IP, L2VPNs, VPLS, L3VPNs, IPv6 and others, a one size fits all approach for load balancing is limited. In this presentation, we will look at the reasons for load sharing, the various layers where load sharing is used, highlight the criteria used for load sharing at each layer and recommend the best schemes to be used for each traffic type to boost network capacity utilization. We will further look at some interesting techniques of speculation in MPLS packets and neutralization of polarization effects in IP networks.

Tutorial: Layer 3 VPN for v4 & v6 in IP Core

Main stream Service provider revenue is coming from providing Business L3VPN. V4 L3VPN have been the key driver all along. Moving forward we will start seeing v6 L3VPN coming into picture due to Federal Mandates. These VPN could be using the MPLS transport or the IP transport in the Service provider core. Traditionally MPLS transport has been widely accepted and deployed. But there are many other providers who have protected their investment by using their existing infrastructure build over IP. With IP Core the same L3VPN for v4/v6 has been successfully being deployed and used. This tutorial goes over the advantages and implementation details of achieving v4/v6 L3VPN over IP core. Vendors like Cisco have products which has demonstrated this and various service providers have deployed the same.

Tutorial: How to Update Wireshark

In today\'s networks there are an increasing number of new protocols and changes to existing protocol changes occurring on an almost daily basis. One of the tried and tested methods of diagnosing problems by networking professionals is using a \'network analyzer\' or sniffer. However, with the velocity of protocol changes the protocol analyser may not have been updated to decode the new formats. This problem is even more common in our test and validation labs. This presentation will give a overview of how Wireshark works from a user perspective. From the developer perspective, layout of the code, commonly used functions, and a walk through of extending Wireshark to support MVPN (multicast VPN) decoding of BGP. Wireshark is free and licensed under GPL.

Tutorial: Best Practices for Determining the Traffic Matrix in IP Networks

Knowledge of the amount of traffic between source and destination pairs of a network is crucial to fundamental operational tasks such as capacity planning, traffic engineering, and peering management. Router vendors, third parties, academic researchers, and ingenious network engineers have devised multiple ways of collecting and estimating traffic matrices. This session presents an overview of applications of traffic matrices and operational experiences with the various approaches, including NetFlow-based methods, mathematical estimation models, and MPLS (both RSVP and LDP) methods. Emphasis will be on practical experiences with each method. The tutorial has been slightly revised since previous versions. There will be less focus on NetFlow (only new advances will be covered), a more detailed description of how to build a traffic matrix from MPLS LDP counters, more coverage of measuring/estimating peering traffic (external in addition to internal traffic matrix). There will also be a discussion of the combination of traffic data with routing information.

Tutorial: NetFlow to guard the Infrastructure

This tutorial aims to cover the uses of NetFlow to monitor an SP\' infrastructure, from the export, router-wise, to the collect and analysis, from a security perspective. While there is certainly a great deal of papers on the subject, there is room - and need, or so I hope - for a comprehensive coverage of NetFlow from theory to practical operations. The questions regularly popping-up in the operators\' forums about NetFlow uses, as well as the lack of visibility most operators have regarding attacks against their infrastructure may be good testimonials to support such a tutorial.

Tutorial: Disaster Recovery & Global Site Load Balancing for Distributed Data Center Applications

Zero downtime is one of the key principles in network design, in particular when building data-centers, where key applications and data need to be accessed at any given time. Content switches have traditionally been used to build scaleable and resilient data-centers offering local load balancing for the data-center front-end and multi-tier architectures. Over the past years enterprises and services providers around the world have started to utilize content switches (often in conjunction with other dedicated GSLB devices) to also provide redundancy across multiple distinct geographic locations. The session introduces Global Server Load Balancing (GSLB) concepts and terminology, like active-standby, active-active, and disaster recovery, before diving into a detailed description of the most common GSLB technologies, including DNS-based solutions, L3-based solutions (Route Health Injection) and HTTP-only mechanisms.

Tutorial: Overview of QoS for Packet-based IP and MPLS Networks<BR>Level: Introductory

With the increased convergence of multi-services at the edge of the provider network, there is a greater need for effective bandwidth management and service differentiation essentially achieved through IP Quality of Service. In order to provide end-to-end scalable IP services, MPLS backbones are being used to achieve this. This has led to a wider deployment of MPLS-based backbones, enabling providers to have the capability to extend service differentiation using MPLS Diffserv techniques. This ability to provide traffic categorization along with traffic engineering and bandwidth management techniques, available through MPLS Traffic Engineering (TE) and Diffserv-Aware Traffic Engineering (DS-TE), allows the service provider an array of choices for end-to-end implementation of Quality of Service. The five key components of QoS include delay, jitter, latency, bandwidth and fairness. Any QoS deployment requires attention to these components. This would be achieved at the edge by initially classifying traffic streams appropriately, then metering them towards providing service-level guarantees and, if needed, marking the streams as per-policy definitions. Subsequently, for effective bandwidth management, congestion avoidance and management techniques need to be implemented for better utilization of the links and for improved distribution of the available resources. <BR><BR> QoS in the MPLS core achieves differentiation using the MPLS EXP (experimental bit) and leverages the above-mentioned techniques. Additionally, there are benefits of providing congestion avoidance in the core by combining MPLS EXP-based classification with path selection and link and node protection schemes enabled by MPLS TE /FRR/ DS-TE. <BR><BR> This tutorial will begin by providing a background to the classical QoS techniques available for packet-based IP and MPLS networks. Subsequently it will introduce the concepts of MPLS Diffserv and briefly discuss the mapping between IP Diffserv and MPLS Diffserv at the edge. It will also briefly touch upon the concepts of MPLS QoS in conjunction with the path selection schemes through MPLS TE/FRR and DS-TE. <BR><BR> The following topics will be covered as part of this tutorial: <UL> <LI> QoS Techniques <UL> <LI> Classification/Marking</LI> <LI> Shaping/Policing</LI> <LI> Queuing/Scheduling</LI> <LI> Congestion Avoidance</LI> </UL> </LI> <LI> QoS in IP/MPLS Edge</LI> <UL> <LI> IP Diffserv (DSCP)</LI> <LI> MPLS Diffserv (EXP)</LI> <LI> Diffserv Tunneling Modes (RFC 3270)</LI> </UL> </LI> <LI> QoS in MPLS Core</LI> <LI> MLPS QoS and Path selection schemes: MPLS TE / FRR / DS-TE</LI> </UL>

Tutorial: L2VPN: Path to Convergence<BR>Level: Introductory

Initially, Virtual Private Networks were built using leased lines. Service providers were offering VPNs based on point-to-point data link layer connectivity, using ATM or Frame Relay virtual circuits. Customers built their own Layer 3 networks to accommodate IP traffic. As a result, separate networks exist for Layer 2 and Layer 3 traffic, but maintaining separate networks for Layer 2 VPNs, Layer 3 VPNs and Internet traffic is difficult and very costly. <BR><BR> In order to maximize return on their assets and minimize their operating costs, service providers often look to consolidate the delivery of multiple service types onto a single networking technology. As packet traffic takes up a larger and larger portion of the available network bandwidth, it becomes increasingly useful to optimize public networks for IP. As a result, service providers are moving to converged IP/MPLS networks, and they need a single infrastructure for delivering Layer 2 (including transport) and Layer 3 services to their internal and external customers. L2VPN is the architectural framework for accomplishing this, regardless of whether the Layer 2 service is ATM, Frame Relay, Ethernet, PPP, or HDLC. L2VPN encapsulates packets at the provider edge router, transports them over the backbone to the provider edge router on the other side of the cloud, removes encapsulation, and sends them to their destination. <BR><BR> The solution has the following benefits: <UL> <LI> Reduces operating expenses (OpEx) and capital expenditures (CapEx)</LI> <LI> Offers a new set of services, such as Metro Ethernet MPLS uses frames or cells. L2VPN can work in IP over ATM networks and IP over MPLS networks</LI> <LI> L2VPN can be combined with Quality of Service and Traffic Engineering to build new revenue-generating services</LI> <LI> VPLS is a service targeted for enterprise networks to connect geographically separate LAN segments together across a WAN. <BR><BR></LI> </UL> In this tutorial we will walk through the following topics: <UL> <LI> Virtual Private Wire Service (VPWS): like-to-like and interworking attachment circuits</LI> <LI> VPLS (Virtual Private Lan Service): point-to-multipoint</LI> <LI> Guaranteed Quality of Service</LI> <LI> Traffic Engineering and fast reroute for L2VPN</LI> <LI> MPLS OAM L2VPN circuits</LI> <LI> Pseudowire redundancy & tunnel stitching</LI> <LI> High availability and reliability</LI> <LI> Convergence</LI> <LI> L2VPN troubleshooting</LI> </UL> L2VPN (interworking & VPLS) demo</LI>

In particular, the tutorial will look at how the amount of state (for example LSPs and forwarding state) is affected by different MPLS signaling protocols, features deployed, and network design choices. Furthermore, the cost of this state in terms of both platform resources and operations/management overhead is evaluated (for example, when is it necessary to upgrade a platform or add a new device in the network, or how difficult is it to configure and troubleshoot a particular deployment?). The material presented is vendor-independent. The tutorial is targeted for network engineers and service providers who want to gain a deeper understanding of MPLS networks. Attendees should have a basic understanding of MPLS and BGP/MPLS VPNs.

Tutorial: Build for Success—How to Use Network Design Principles to Differentiate the Good, the Bad, and the Ugly

First-generation commercial Internet network engineers used key principles in the way they built, deployed, and operated their networks. The principles were derived and deployed from core theorems that proved to scale during times of exponential growth. Until the publication of RFC 3439, \"Some Internet Architectural Guidelines and Philosophy,\" these principles were undocumented and rarely passed to the next generation of network engineers. This primer discusses in detail the core principles highlighted in RFC 3439 and reviews some of the assumed fundamentals of functional, hierarchical, and modular design that are core tools for today\'s network designs. <A HREF=\"http://www.1-4-5.net/~dmm/talks/NANOG33/designing/\">http://www.1-4-5.net/~dmm/talks/NANOG33/designing/</A>

Tutorial: Deploying IP Anycast

IP Anycast is an older technology that has seen a bit of a resurgence in recent months, perhaps encouraged by its use in providing several of the root servers. In designating certain unicast addresses as \'anycast,\' operators configure these addresses on multiple machines, and configure routes to each host. When traffic is directed to an anycast address, routers select one path from potentially several valid paths to forward traffic (thus, no change from traditional unicast forwarding). One server receives each packet and responds to the requester. In configuring multiple hosts to respond to the same address, stateless protocols such as DNS can be easily scaled. Servers can be located in closer proximity to clients, providing faster responses to queries. In the event of a single host failure, routes can quickly be withdrawn and servers in other locations handle the request traffic, all without any changes to client configurations. Recursive DNS clients built into many of today\'s operating systems deal rather poorly with a failure of their primary recursive server. Of eight operating systems evaluated in a recent survey, seven kept no history of failed servers, trying each DNS query against the first server and waiting for a response before moving to secondary servers. Using anycast, service is maintained even in the face of a single or multiple host failure. This substantially reduces resolution delays due to server failure. DNS will serve as an example of successful anycast use, but the strategies described are also applicable to other stateless protocols.

Tutorial: ISP Security: Deploying and Using Sinkholes

Sinkholes are a flexible security tool that add a wealth of new capabilities to an ISP\'s security toolkit. ISPs are using sinkholes to track infrastructure port scanning, identify and classify attacks, packet capture attack flows, trace attacks through their networks, and divert attack flows from the target of the attacks. Sinkholes also enable a variety of new applications brought about through necessity and growing operational experience. Sinkholes go beyond narrowly focused tools like black hole servers, Tarpits, and Honeynets. Sinkholes may be used to perform any or all of these functions, but often incorporate all of these and more. This tutorial will explain how to build a sinkhole, using generalized examples from ISP deployments around the world. Configuration using JUNOS and IOS will be used to demonstrate the various ways trigger routers and target routers in the sinkholes are safely, scalably, and efficiently configured. Architectural considerations relating to network topology and placement of sinkholes in the ISP\'s network will be covered, along with anycast deployment options. A multitude of tools that can be placed inside the sinkhole will also be discussed. These include a variety of freeware, shareware, home-built, and commercial tools - covering the diversity available to ISPs of any size. This tutorial is recommended to ISP engineers of all experience levels. The source materials are derived from live operational deployments, which can be modified and applied to any large IP transport network.

Tutorial: Managing IP Networks with Free Software

Many of the largest IP network operators in the Internet rely on free software to keep their packets moving, and to allow their staff to sleep occasionally. The choice of free software over commercial alternatives is often a pragmatic one; the wide variety of policies, procedures, platforms and services in different networks require a degree of flexibility in deployment and integration that is often not available with off-the-shelf software. <BR><BR> The flexibility of free software in solving complex tasks can also present complexity to the operator; the part of the solution that is usually not free is the architectural design into which free software components are inserted. <BR><BR> This tutorial will discuss a number of opportunities for automating routine netops housework using free software, loosely assembled under the theme of gathering state from the network and visualising it in useful ways. Applications which will be discussed in some detail include: <UL> <LI> Configuration change measurement: storing the configuration history of your network in a useful way; <BR><BR></LI> <LI> Automatic network configuration audits: self-consistency checks wired to loud alarm bells; <BR><BR></LI> <LI> Automatic generation of DNS records for router interfaces, in the interests of traceroute beautification; <BR><BR></LI> <LI> Automatic generation of graphical maps to help operators visualise live topologies as their networks evolve; <BR><BR></LI> <LI> Gathering data from BGP peers to help in choosing \"maximum-prefix\" session limits. <BR><BR></LI> </UL> The tutorial will not provide instruction on particular programming languages or packages, but will rather illustrate how individual software components can be treated as black boxes, glued together under a Grand Scheme to make operators\' lives easier.

Tutorial: IP Traffic Management: Measurement, Analysis, and Optimization

A provider\'s success is increasingly being influenced by its ability to monitor and engineer its traffic performance - both within its domain and between its domain and other AS\'s. Key data required for both inter- and intra-domain traffic engineering (TE) include information on routing, traffic loads, bandwidth, and path performance. This tutorial focuses on application of TE for inter-domain purposes. This includes short-term traffic management requirements such as debugging, congestion mitigation, and routing optimization; as well as long-term planning involving capacity planning, peering analysis, and load balancing. The first half of this tutorial provides an overview of techniques that can be used by large, complex networks to expand their visibility into and control of traffic moving between their network and other domains (it recaps key points from the NANOG24 Inter-domain Traffic Engineering tutorial). The second half of the tutorial provides specific examples and case studies of inter-domain TE from commercial networks, including MFN and Global Crossing. A case example from Exodus also demonstrates how data gathered for inter-domain TE can be used for intra-domain TE purposes, e.g., use of BGPNextHop in optimizing internal routing.

Tutorial: Inter-domain Traffic Engineering: Principles, Applications, and Case Studies

The Internet is a mesh of interconnected networks, each striving to control its network operating costs, optimize end-to-end performance for customers, and differentiate its IP services from those of competing providers. Increasingly, a provider\'s success will be determined by its ability to monitor and engineer its inter-domain traffic performance.<BR> <BR> Traditional traffic engineering (TE) techniques focus on intra-domain control features, particularly those associated with multi-protocol label switching (MPLS) within an infrastructure. Newer traffic monitoring and analysis solutions are supporting collection and correlation of multiple network metrics, specifically, inter-domain routing, traffic and path performance data. The emerging traffic engineering systems are oriented toward goals of optimizing network performance while controlling costs associated with operations at the edges of networks, i.e., the points where traffic is exchanged with other networks.<BR> <BR> This tutorial provides an overview of techniques that can be used by networks to expand visibility into and control of traffic moving between their network and other domains. The focus is on analysis methodologies and case examples of how inter-domain TE can be used by networks to support cost-effective peering analysis and planning for new capacity and services, as well as real-time routing and traffic management.

Tutorial: ISP Security - Real World Techniques II

The Internet is a battleground, with ISP\'s and their customers right in the middle of the line of fire. What ISPs need to protect themselves are tools and techniques that work in the line of fire, i.e., tools that fight DoS attacks and provide something other than a busy signal on the customer service line.<BR> <BR> This tutorial will walk ISPs through the five stages of working an attack: preparation, identification, classification, traceback, and reaction. Focus will be placed on techniques that work - with specific vendor features left for other sessions. All the techniques have been validated and proven to be operationally deployable and workable under conditions of network stress. The key objective is to empower other ISPs to deploy these vendor-independent techniques, which will provide a foundation for inter-NOC cooperation to trace back the attacks to their source.

Tutorial: Packets and Photons: The Emerging Two-Layer Network

This session highlights new techologies for optical-based networks. The tutorial begins by examining how service providers have constructed their networks in the past in order to cope with the need for IP bandwidth. System equipment layers are discussed, and how they are now being collapsed into an emerging two-layer network. Future technology directions are then explored, including pure photonic routers. We then discuss how network architectures will look, along with their benefits. An in-depth look is taken at generalized MPLS (GMPLS), which allows the IP routing layer to share a common control plane with the optical transmission layer. The importance of this is explained and why it could be the basis for building IP service infrastructures of the future.

Tutorial: Exterior Routing 201: The Full Picture

BGP is an essential part of ISP routing, but successful ISP routing includes far more than the protocol itself. Obtaining and managing address space, obtaining an AS number, and creating and registering routing policies are critical parts of operations. Understanding convergence requirements and other performance objectives for ISP routers also is important. This presentation will focus on BGP in the larger context, rather than being a basic protocol and configuration guide, as in Berkowitz\' previous NANOG tutorials.

Tutorial: Customer Satisfaction 201

The most important aspect of satisfying an ISP customer is to ensure the customer has realistic expectations, and then to satisfy those expectations. Many customer desires center around \"high availability,\" but there is an unfortunate tendency to focus on only one technology (e.g., multihomed BGP) to solve these problems.<BR> <BR> This tutorial reviews how to define your customer requirements with respect to availability and scalability. It identifies the capabilities and limitations of a wide range of complementary functions at multiple OSI layers, from physical diversity to virtual server farms. It also considers the issues of communicating with customers while problems occur. Previous related tutorials include Berkowitz\' NANOG14 tutorial on address management for ISPs and their customers (Atlanta, 1998).

Tutorial: BGP Configuration From the IRR

This tutorial introduces the Internet Routing Registry (IRR), the Routing Policy Specification Language, (RPSL) and the RtConfig router configuration tool. We explain how to register and query routing policy objects in the IRR. After a brief introduction to routing policies, we discuss RPSL, the language for specifying Internet routing policies in the IRR. We explain several policy examples currently practiced in the Internet and specify them using RPSL. These include as-path prepending, setting preferences and other metrics based on the community attribute, and access lists based on prefix and as-path expressions. <BR><BR> RtConfig is the focus of this tutorial. RtConfig can configure Cisco, Juniper, Nortel, Gated and RSd routers with BGP policies. The amount of configuration it performs is controllable; hence, the amount of information that needs to be published in the IRR is controllable as well. RtConfig can be used to only generate prefix access lists from the IRR, or to generate full-blown router configurations.

Tutorial: Crafting Confederations

The purpose of this tutorial is to present a framework for the construction of a BGP architecture for mid- to large-sized ISPs utilizing BGP confederations. The primary building block for this approach is the concept of the \"POP as Confederation\". While concentrating on theory, this session will also highlight the real world implementation of this approach on Cisco routers at Mindsping, and on Juniper routers at NetRail. Elements include: <UL> <LI> Meaningful MEDs for customers, as well as basic, non-MPLS traffic engineering. <BR><BR></LI> <LI> A well thought-out community structure to optimize route filtering and propagation. <BR><BR></LI> <LI> Special areas of interest include supporting wholesale dialup and broadband providers (OPN) and allowing customers the maximum possible control of their routing. <BR><BR></LI> </UL> With the rise of a new generation of service providers, many of which are based on broadband technologies, there is an opportunity to take a new look at service provider design. This session is designed to address the concerns of such emerging providers as they outgrow their current architectures and look for new approaches.

Tutorial: Routing Policy Specification Language/IRR

This tutorial introduces the Internet Routing Registry (IRR) and the Routing Policy Specification Language (RPSL). We explain how to register and query routing policy objects in the IRR. After a brief introduction to routing policies, we discuss RPSL, the new IETF-proposed standard language for specifying Internet routing policies. RPSL is currently being deployed by IRR participants and will replace RIPE-181, the current IRR routing policy specification language. RPSL provides substantial extensions to RIPE-181, making it possible to specify a much richer set of routing policies in a more concise manner. In addition, we present and demonstrate several IRR policy analysis tools, including RtConfig to configure routers, and roe to reconcile route objects with actual routes in the Internet.
