Tutorial: BGP Multihoming Techniques

This tutorial introduces service providers to some of the features available in BGP to aid multihoming to the Internet. After an explanation of multihoming and the principles being followed in this tutorial, several examples involving different scenarios will be given. This includes the options available when multihoming to the same ISP (including RFC2270) and to different upstreams. Configurations for modifying inbound and outbound traffic flows are covered. The tutorial concludes with a case study and an examination of the use of BGP communities by several ISPs.

Tutorial: Options for Blackhole and Discard Routing

This intermediate-level tutorial offers attendees a view of some common practices for operating a blackhole service. As security concerns abound in the Internet, operators and providers are constantly exploring methods for protecting their networks and customers. During this intermediate-level tutorial we assume that attendees have basic IGP and BGP networking skills. We then build on this basic knowledge by discussing announcement methods for blackholing traffic across the network. In addition, some options for counting and logging the discarded traffic are discussed. Throughout the tutorial, operational and configuration commands from multiple vendors are used to illustrate the tutorial concepts. <BR><BR> A brief outline of the material follows: <OL> <LI> Assumptions</LI> <LI> Discard options <UL> <LI> Static route to null</LI> <LI> Discard interface </LI></UL></LI> <LI> Mapping addresses to blackhole services <UL> <LI> BGP advertisements</LI> <LI> Communities</LI> <LI> Multihop options</LI> <LI> Altering next hop</LI> </UL></LI> <LI> Injecting routes <UL> <LI> Dedicated server</LI> <LI> Accepting routes from customers</LI> <LI> Accepting routes from peers</LI> </UL></LI> <LI> Accounting and Counting Options</LI> <UL> <LI> Filters</LI> <LI> ACLs</LI> <LI> Counters</LI> <LI> Syslog</LI> <LI> Logging</LI> </UL></LI> <LI> Who to discard? <UL> <LI> Attacks from customers</LI> <LI> Attacks to customers</LI> <LI> Unallocated address space (bogons?)</LI> <LI> Attacks from peers</LI> </UL> </LI></OL>

Good Engineering Practice as it Applies to Unlicensed Wireless Networks

Unlicensed wireless radios such as 802.11 systems have significantly reduced the cost and technical knowledge needed to deploy wireless networking. The technology is now attractive not only for the office and home user, but also to ISPs for last-mile, to educational institutions and corporations for campus networking, and for the Internet activist working on full neighborhood connectivity. Unfortunately, by its nature, unlicensed wireless networks will encounter more interference as more users dive in. This talk will cover some of design principals to get the most from your wireless deployments.

802.1X: Deployment Experiences and Obstacles to Widespread Adoption

Ratified as an IEEE standard in 2001, 802.1X defines port-based network access control. While providing a host of benefits to network operators, adoption of 802.1X has been slow--much slower than the rapid deployment experienced by 802.11b. <BR><BR> This presentation highlights 802.1X deployment experiences at a number of institutions, focusing particularly on lessons learned that will (we hope) serve to aid others in deploying this technology. <BR><BR> Additionally, there are a number of obstacles that have yet to be satisfactorily resolved and impede many organizations from deploying 802.1X. These include vendor implementation issues, client compatibility problems, and the rate of change in encryption standards and associated client software support.

Research Forum: Performing BGP Experiments on a Semi-Realistic Internet Environment

Various techniques to protect BGP routing have been proposed. To be deployed, these techniques must be rigorously tested and evaluated. Deter/ Emist routing group is building a routing testbed to create an experimental infrastructure and developing evaluation methods. In this talk, we describe the testbed architecture and share experience gained learned in the testbed setup. <BR><BR> To create realistic BGP dynamics, we inject live Internet BGP routing traffic into the testbed. We have also developed an integrated statistical and visual-based anomaly detection engine to analyze and visualize the BGP dynamics. For the first step, we conduct two BGP attack experiments: an origin AS change attack and a differential damping penalty attack. In the damping attack, we discover the subtle implementation difference between zebra router and Cisco router, which causes the different attack effects.

Research Forum: Sizing Router Buffers

All Internet routers contain buffers to hold packets during times of congestion. Today, the size of the buffers is determined by the dynamics of TCP\'s congestion control algorithm. In particular, the goal is to make sure that when a link is congested, it is busy 100% of the time; which is equivalent to making sure its buffer never goes empty. A widely used rule-of-thumb states that each link needs a buffer of size B = RTT X C, where RTT is the average round-trip time of a flow passing across the link, and C is the data rate of the link. For example, a 10Gb/s router linecard needs approximately 250ms X 10Gb/s = 2.5Gbits of buffers; and the amount of buffering grows linearly with the line-rate. Such large buffers are challenging for router manufacturers, who must use large, slow, off-chip DRAMs. And queueing delays can be long, have high variance, and may destabilize the congestion control algorithms. <BR><BR> In this talk we argue that the rule-of-thumb B = RTT X C is now outdated and incorrect for backbone routers. This is because of the large number of flows (TCP connections) multiplexed together on a single backbone link. Using theory, simulation and experiments on a network of real routers, we show that a link with n flows requires no more than B =(RTT X C) / sqrt{n}, for long-lived or short-lived TCP flows. The consequences on router design are enormous: A 2.5Gb/s link carrying 10,000 flows could reduce its buffers by 99% with negligible difference in throughput; and a 10Gb/s link carrying 50,000 flows requires only 10Mbits of buffering, which can easily be implemented using fast, on-chip SRAM. <BR><BR> We also present recent data on how a live network with real traffic performs with reduced router buffers.

SP Security and NSP-SEC BOF VII

Security incidents are a daily event for Internet Service Providers. Attacks on an ISP\'s customers, attacks from an ISP\'s customer, worms, BOTNETs, and attacks on the ISP\'s infrastructure are now one of many \"security\" NOC tickets through out the day. This increase in the volume and intensity of attacks has forced ISP\'s to spend constrained resources to mitigate the effects of these attacks on their operations and services. This investment has helped minimize the effects of the attacks, but it has not helped stop them at the source. Stopping attacks at their source requires rapid and effective inter-ISP cooperation. Hence, these ISP Security BOFs are also used as a face-to-face syncup meeting for the NSP-SEC forum (see https://puck.nether.net/mailman/listinfo/nsp-security.)

Evolving the Core: Deployment Challenges and the Internet

In a post 9/11 world, there is great interest in enhancing the ability of telecommunications networks and other critical infrastructures to withstand terrorist attacks. Wherever possible, there is a strong desire to use market mechanisms to drive necessary changes. <BR><BR> Might there be instances where market forces would not motivate necessary change, or might not drive it quickly enough? Is there a role for government in such cases, and if so how might government best intervene, with as little burden or market distortion as possible? What risks might be associated with trigger-happy or ill-advised interventions? Do those risks exceed the risks that might be associated with a failure to intervene when legitimately needed? <BR><BR> Two recent government studies bear on this issue. One is a report from the NIAC, a presidential advisory committee: \"Best Practices for Government to Enhance the Security of National Critical Infrastructures\". Another is a report by the NTIA (a unit of the Department of Commerce) on IPv6.

DNS Anomalies and Their Impact on DNS Cache Servers

Recently we have observed various types of DNS anomalies due not only to misconfigurations such as lame delegations, but also due to malicious DoS attacks on DNS servers. However, discussion of DNS anomalies are mainly focused on DNS root servers and authoritative servers, and DNS cache servers have been hidden inside providers and rarely exposed. <BR><BR> The authors report their experiences with high-load DNS cache servers with regard to worms and misconfigurations. Although providers are always preparing such high loads, everybody will be happy if unnecessary DNS queries are avoided. Firstly, the authors describe the heavy load caused by worms, and suggest how to avoid the problem. Secondly, the authors present the heavy load caused by an authoritative server which has oversize records. The authors propose modifying BIND as a workaround.

  • Rob Austein is a software engineer at the Internet Systems Consortium. Prior to his incarceration at ISC, he also served time at InterNetShare, Inc., Integrated Systems, Inc., Epilogue Technology Corporation, and MIT\'s Laboratory for Computer Science. After spending a number of years working on everything from mainframes to deeply embedded systems, Rob has at one time or another worked at almost every layer of the protocol stack, but feels most at home somewhere around layer 3. He is, however, probably best known for having wandered aimlessly into the early specification and deployment of the DNS, and, as a result, has spent entirely too much of the intervening time at layer 9. At present, Rob spends 50 weeks out of every year trying to figure out how (and why) the Internet works; the other two weeks of each year are usually devoted to gravitational research in the Tetons.

Tracking Global Threats with the Internet Motion Sensor

As national utility infrastructures become intertwined with emerging global data networks, the stability and integrity of the two have become synonymous. This connection, while necessary, leaves network assets vulnerable to the rapidly moving threats of today\'s Internet, including distributed denial of service attacks, fast moving worms, and routing exploits. This presentation introduces the Internet Motion Sensor (IMS), a globally scoped Internet monitoring system whose goal is to measure, characterize, and track threats. <BR><BR> The IMS architecture is based on three novel components. First, a Distributed Monitoring Infrastructure increases visibility into global threats. Second, a Lightweight Active Responder provides enough interactivity that traffic on the same service can be differentiated independent of application semantics. Third, a Payload Signatures and Caching mechanism avoids recording duplicated payloads reducing overhead and assists in identifying new and unique payloads. We explore the benefits of this system in the context of a three-year deployment across multiple dark address blocks ranging in size from /24s to a /8. Data gathered from these deployments is used to demonstrate the ability of the IMS to capture and characterize recent activity, such as that on Sasser and Dabber Backdoors.

Detecting Inconsistent Advertisements from Neighboring ASes

Internet Service Providers often establish contractual peering agreements, in which they agree to forward traffic to each other\'s customers at no cost. \"Consistent route advertisement at all peering points\" is a common provision in these agreements, because it gives an AS the flexibility to select egress points for the traffic (e.g., performing \"hot potato\" routing). Verifying \"consistent export\" is challenging because route advertisements are exchanged at multiple peering points and may be modified by routing policies. <BR><BR> In this talk, we propose two algorithms to detect inconsistent routes using routing and configuration data from an AS\'s border routers. The first algorithm requires access to all eBGP routes advertised by a peer. Because this data is often unavailable, we propose another algorithm that detects inconsistencies using readily available data. <BR><BR> We have applied our algorithms to the routes advertised by the peers of AT&T\'s commercial IP backbone. Although a peer may intentionally send inconsistent advertisements to prevent its neighbor from performing hot-potato routing, we also discuss several configuration scenarios in which a peer may inadvertently advertise inconsistent routes, despite having consistent export policies. Finally, we explain how simple modifications to the routers could make detection of inconsistent advertisements much easier than it is today. <BR><BR> A writeup that explains our algorithms and experience in further detail is available at: <BR><BR> <A HREF=\"http://nms.lcs.mit.edu/~feamster/papers/bg-imc04.pdf\">http://nms.lcs.mit.edu/~feamster/papers/bg-imc04.pdf</A>

LinkRank: A Tool for Diagnosis of BGP Routing Dynamics

This talk presents the Link-Rank tool for monitoring BGP dynamics. Network events such as failures and policy changes cause routes to change, and often result in a ripple effect observed at various places with a large number of BGP updates. \"Link-Rank\", a Java-based graphical toolset, is designed to help extract routing change dynamics from the multiple gigabytes of BGP log data. Link-Rank weights the links between Autonomous Systems by the number of routing prefixes going through each link and generates Rank-Change graphs that capture the route changes in each time interval. A time series animation presents these rank-change graphs in an easy-to-understand manner. The toolset also provides a feature to combine views from multiple observation points to give a more complete picture of BGP dynamics. Using the Link-Rank toolset, we show how these graphs can be used to understand BGP route change events and narrow down possible locations that originated the changes. We also show how combining views into a single graph can increase the accuracy of event diagnosis and provide useful insight. This work complements existing toolsets such as BGPlay, which focus on routing changes to a single (or small number) of prefixes. By presenting views from multiple vantage points, Link-Rank provides a large-scale picture. This broad view can then be used to identify individual prefixes for further detailed examination by BGPlay to produce better insights.

Life and Times of J-Root

VeriSign operates j.root-servers.net. This server has undergone some interesting changes in the past two years. In November, 2002, the server\'s IP was changed and we will present data surrounding the renumbering event. Starting in early 2003, we began anycasting this server. Now with more than a dozen sites, we will present data surrounding the distribution of queries to the various anycast instances, focusing on geolocation. Finally, the old IP address of j.root-servers.net continues to receive traffic two years after having been renumbered. We will present an analysis of the specific traffic received.
