Full Abstract

Managing and maintaining highly scalable networks has historically been a challenging task. A plethora of ISPs/CSPs have been trying to simplify processes and procedures; yet this task gets more complicated as they are faced with the growing cost pressure of supporting today’s IP network traffic demands (driven by video, gaming, and remote working) and future 5G traffic volumes. All these trends and market forces are forcing cable operators to rethink and rearchitect their legacy IP networks and operations in ways that can give them a competitive edge.

The intent of this presentation is first to describe why distributed disaggregated services such as a Disaggregated Distributed Chassis (DDC) will be paramount for the success of ISPs/CSPs. It will examine how these services differ from traditional architectures, and which operational processes, engineering skills and supporting tools are needed. It will showcase an example of the DDC model deployed in the production environment of one of the largest cable operators in the world. It also will provide insights on how to improve network availability and reliability thanks to a smaller “blast radius” for outages.

In summation, ISPs/CSPs’ interest in network disaggregation has been growing, driven by a variety of motives such as cost reduction, the removal of vendor lock-in and service innovation. Readers will have a granular understanding of the operational impacts of the DDC approach, and how networks can be managed in a more cloud-like and orchestrated manner. They will also achieve a clear vision for solving operational and business challenges before embarking on a disaggregation project.

Full Abstract

As network engineers begin adopting automation in their organizations, they inevitably encounter a range of challenges. These are typically accepted as necessary engineering hurdles that need to be overcome in order to bring automation into production, and are subsequently addressed with a mix of de facto standard tooling and traditional training. Unfortunately, this logical but simplistic strategy overlooks some powerful alternatives by which automation can be introduced and even adopted. Chances are, opportunities for accelerating network automation already exist in your organization.

In this practical talk we will discuss several alternative strategies to begin automating networks. Engineers who are struggling with the basics will learn new perspectives for addressing automation challenges. We will also introduce a flexible maturity model and a proposed framework for full-cycle automation deployment to aid in examining these uncommon paths to beginning network automation.

Cloud Network Engineering: A closer look at a new career path

What will be presented
Cloud Network Engineering as a career path; Soup to Nuts. This is a 60 minutes presentation to introduce the emerging career of a CNE or Cloud Network Engineer.

We believe this career has roots deep in a few different engineering fields such as network, systems and security engineering. This will be covered as part of the “intro” (part 1).

In the second part the presenter will move on to the responsibilities and required skillsets (Part 2).

Why do we need this session?
The most recent NANOG surveys have showed us that many participants are interested in learning about career development. Furthermore, a brief field study reveals that very little research has been conducted in this field although today there are over 19,700 postings for this type of candidates exist on LinkedIn. Finally, I believe this session has other potentials including attracting sponsors and its recoding for years to come will be used as a reference by thousands of people.

Who is our target audience?
Network engineers and operators almost in any part of their career.
Hiring managers in the field of network and cloud engineering.
Talent advisors.
Technical content developers and vendors.

Full Abstract

Our current networks depend on fiber technology. This talk describes what it took to develop compact 400 Gigabit technology during the global pandemic. The current realities of compact 400g are discussed.
Presenter Len Bosack, founder of Cisco systems, oversaw the development of 400G products during lockdown and recovery. It was a bumpy ride. As the pandemic progressed, most of the back-room vendors had significant problems -- being crowned by the famous supply-chain collapse. At times, only one person was allowed in the building. Notwithstanding these, product development still happened. The XKL compact 400G products are the result.

Len Bosack: As CEO of XKL, LLC, a leading optical networking equipment provider, Leonard Bosack continues to drive technology innovation in his quest to bring fundamental change to worldwide telecommunications. Bosack co-founded Cisco Systems in 1984 and is mainly responsible for pioneering the widespread commercialization of local area network (LAN) technology and the interconnections which form the internet.

Full Abstract

How often do you find yourself doing the same set of commands when troubleshooting issues in your network? I am willing to bet the answer to this is quite often! Usually we have a list of our favorite commands that we will always use to quickly narrow down a specific problem type.

Switch reloaded unexpectedly? "show reload cause"
Fan failure? "show environment power"
Fiber link reporting high errors or down on your monitoring system? "show interface counters errors", "show interface transceiver", "show interface mac detail"

Outputs like the above examples help you quickly pinpoint the source of your failures for remediation. SSH'ing into the boxes and running these commands by hand is time consuming, especially if you are for example a NOC dealing with numerous failures throughout the day. Most switch platforms have API's now and you can instead program against them to get these outputs in seconds. I will go over a variety of examples and creative ways to use these scripts for optimal use of your troubleshooting time and to get you away from continually doing these repetitive tasks by hand.

NOTE: My tutorial examples will be using python and the Arista pyeapi module with Arista examples, but the concepts can easily be transferred to other platforms and languages.

Full Abstract

When an IP network is congested, operators could take advantage of the channel margins in the underlying optical network and increase capacity of the IP links. Although channel margins are required for the long-term health of the optical service, it might be possible to tap into the margin while the IP network is being repaired. We present a new converged Traffic Engineering SDN approach that looks at the IP and optical layers of the network holistically to help operators alleviate IP congestion.

Full Abstract

gRIBI is a control plane gRPC service that enables an external entity (say a controller) to inject and query entries into a network device’s RIB. The data model to represent the entries reuses the OpenConfig Abstract Forwarding Table (AFT). Since the entries are injected into the RIB, there’s no need for the external entity to assume full ownership of the forwarding table nor be aware of all the forwarding entries. Programming operations are transactional with support for acknowledgements (per operation) of installed state in the device’s RIB and (hardware) FIB. Use of gRPC and AFT data model allows for vendor neutral support on the external entity.

Full Abstract

Mary Walton, in her book “The Deming Management Method”, says “In God we trust. All others must use data.” Over the last 20 years, my colleagues and I have been engaged in understanding and improving the Internet through large-scale measurement, and of course, data. Using a variety of measurement tools, ranging from Internet telescopes to active scanning to Netflow, we set about the task of collecting measurements about Internet protocols, such as IPv4 and IPv6, services, such as BGP and DNS, and applications, including email and the web. Our work has focused primarily on improving the security and availability properties of these components and we have studied everything from man-in-the-middle attacks to spam, worms, botnets, and DDoS. Over time, what questions we ask and how we seek to answer them have co-evolved and, somewhat surprisingly, our approach today can best be understood not through traditional network measurement, but through the lens of security principles. I’ll argue that this philosophy is something worthy of emulation, not only in its ability to understand and improve the quality of our networks and services today, but also as a way of thinking about the design, adoption, and operation of tomorrow’s networks.

Full Abstract

Sophisticated attackers, typically nation-state actors, have begun to leverage access to key DNS infrastructure to then hijack target organization domains. Target organizations now not only
include government domains, but also large network operators. Most concerningly, these domain hijacks bypass traditional DNS protections, and are imperceptible to the users. In this talk, we describe our methodology for identifying domain hijacks in the wild, and our results from using this methodology to identify a range of victims demonstrating that domain hijacks have evolved into a favored intrusion tactic. Finally, we also discuss what these findings mean for organizations looking to secure their infrastructure.

Full Abstract

We analyze the properties of 712 prefixes that appeared in Spamhaus’
Don’t Route Or Peer (DROP) list over a nearly three-year period
from June 2019 to March 2022. We show that attackers are subverting multiple defenses against malicious use of address space,
including creating fraudulent Internet Routing Registry records for
prefixes shortly before using them. Other attackers disguised their
activities by announcing routes with spoofed origin ASes consistent
with historic route announcements, and in one case, with the ASN
in a Route Origin Authorization. We quantify the substantial and
actively-exploited attack surface in unrouted address space, which
warrants reconsideration of RPKI eligibility restrictions by RIRs,
and reconsideration of AS0 policies by both operators and RIRs.

Full Abstract

Pluggable Digital Coherent Optics (DCO) is a breakthrough technology that allows routers to integrate state of the art coherent DWDM interfaces without the need for specialized hardware. This is possible thanks to the incredible power efficiencies and compactness of recent DCO implementations over QSFP56-DD and other transceivers that can be deployed directly into standard 400GE host ports. Replacing traditional DWDM transponders by pluggable DCO significantly lowers the cost of building high-speed networks with massive capacity and extended reaches. Even greater gains in cost efficiencies are possible with Routed Optical Networking, a novel network architecture that couples DCO with innovations in IP/MPLS, management and automation to build a fully converged and programmable network architecture optimized at the packet switching layer.

As the industry embraces DCO, adoption increases and new use cases are explored, questions about how to manage this technology when deployed in the routers emerge. What are the new optical parameters that DCO expose to the router? How to leverage them for pro-active fiber and DWDM performance management? How to give visibility of that data to fellow transport operations teams and data lakes without exposing the IP network details?

This session will present DCO technology covering its basic concepts, the new optical signal monitoring capabilities enabled by its built-in the Digital Signal Processors (DSPs) and transport encapsulations, and how they can be used to enhance IP networks and their operations. It will also discuss the state of the industry standards and open networking initiatives that can be leveraged to build a multi-vendor ecosystem.

IPv4 is exhausted. We can do a better job of being efficient with our IPv4 utilization while also making IPv6 a reality in our networks. The perfect combination is dual-stacking IPv4 CGNAT and IPv6. Utilizing RFC6598 space, we can extend a dedicated VLAN per customer to make IPv6 EUI-64 possible without running out of IPv4 space to assign with it.

The need to reliably monitor today’s ever-growing networks in the WAN, edge, and data center domains is now more critical than ever. The industry relies largely on SNMP to monitor present networks, a protocol that falls short when used to monitor large networks let alone the increasingly complex networks of the future.

Openconfig's gRPC-based streaming telemetry protocol, gNMI is considered by many to be the prime successor to SNMP. It packs features to build modern monitoring stacks, such as a push-based telemetry model, reliable transport, default TLS security, data model-based access to monitored data leaves, and exceptional performance on the wire.

This tutorial introduces gNMIc, an open-source software suite which blends together a feature-rich gNMI CLI client and a performant, highly-available telemetry collector. Focusing on gNMI-based streaming telemetry, gNMIc sets itself apart from other general-purpose collectors with unique features including high availability and clustering of collector instances, rich data processing pipelines, sheer support for various outputs for metrics, and embedded caching, to name a few.

By the end of this session, participants will understand how gNMIc can be used to configure network devices, and building a modern open-source telemetry stack comprised of a collector, time-series DB, and visualization layer.

Habits die hard, and the concepts of address allocation which are perfectly valid for IPv4 just don't work for IPv6, and in fact some IPv4 habits will technically break IPv6 routing efficiency.

This is a summary of good address allocation hygiene when people have large blocks to split up, based on RFC suggestions and fifteen years of operational experience in IPv6

Recent research studies highlighted a phenomenon known as “BGP zombies", which refers to active RIB entries for prefixes that have been withdrawn, but still persist in BGP routing tables.
The research has investigated the prevalence and characteristics of BGP zombies, with a focus on data collected from RIPE RIS, and found that ASes announcing a high number of prefixes, and also prefixes with a higher degree of "noise" (e.g. BGP beacons), are more likely to have BGP zombies.
In this presentation, we aim to raise awareness to the BGP zombie phenomenon and extend previous work by investigating:

• the identification of BGP zombies using a BGP monitoring platform other than RIPE RIS (namely the Code BGP Platform) will yield comparable results to those obtained from RIS Live
• whether announcing a limited number of new prefixes, originated from a new AS not announcing other prefixes, will still result in BGP zombies

Our results reveal that BGP zombies are a pervasive problem in the Internet routing system, regardless of the monitoring platform and prefix announcement characteristics utilized. We advocate that monitoring platforms should develop mechanisms for accurately identifying and labeling BGP routes as zombies, as well as implementing strategies for promptly alerting users to their presence in order to mitigate the potential negative effects they may have on network stability and performance.

DE-CIX has been working on the introduction of EVPN on its peering platform since the beginning of 2022. Considering the increasing number of participants, especially in New York and Frankfurt, the introduction of EVPN, including ProxyARP/ND, is required to get the exponentially growing broadcast/multicast traffic in the Peering LANs under control and to reduce the load on customer routers. Additionally, further security features based on a ProxyARP/ND agent according to RFC 9161 are activated and the protocol stack of the DE-CIX global network will be expanded to include RSVP-TE and sBFD. In this presentation, we will present the course of the project, benefits, and side effects for DE-CIX customers explained in technical detail.

Full Abstract

Video-conferencing applications impose high loads and stringent performance requirements on the network. To better understand and manage these applications, we need effective ways to measure performance in the wild. For example, these measurements would help network operators in capacity planning, troubleshooting, and setting QoS policies. Unfortunately, large-scale measurements of production networks cannot rely on end-host cooperation, and an in-depth analysis of packet traces requires knowledge of the header formats. Zoom is one of the most sophisticated and popular applications, but it uses a proprietary network protocol. In this talk, we demystify how Zoom works at the packet level, and design techniques for analyzing Zoom performance from packet traces. We conduct systematic controlled experiments to discover the relevant unencrypted fields in Zoom packets, as well as how to group streams into meetings and how to identify peer-to-peer meetings. We show how to use the header fields to compute metrics like media bit rates, frame sizes and rates, and latency and jitter, and demonstrate the value of these fine-grained metrics on a 12-hour trace of Zoom traffic on our campus network.

Oliver Michel: Oliver Michel is a postdoctoral researcher at Princeton University working with Professor Jennifer Rexford. He received his Ph.D. from the University of Colorado Boulder. Oliver’s research focuses on network support for real-time video-conferencing applications, scalable packet-level network monitoring, programmable data planes, and high-performance software packet processing.

Synopsis: Measurement Lab and Cloudflare want to empower network operators with free and open access to data that represents their user’s experience. Our presentation will:

1. Discuss how end-users define “good Internet” and how AIMScore defines the answer
2. Announce the free and open availability of AIMScore data that enable network operators to get actionable insights from CloudFlare and Measurement Lab’s speed tests
3.Solicit feedback from NANOG community about access and usability of the data and discuss future milestones

Running a distributed network is a challenge by itself, but ensuring that users are having a good experience on that network adds a layer of complexity that can make anyone’s head spin. It’s hard enough ensuring that users can reach the Internet through your network, but ensuring that they can access a myriad of services and applications at peak performance for each is orders of magnitude harder, especially when each application has a different concept of what peak performance looks like. To put it another way: it’s hard enough to know if every user on your network can access Discord, Netflix, and Dota reliably, but it’s even harder to know if every user on your network has a good experience accessing those services because each of those have completely different understandings of what it means to have a good experience.

The way we use the Internet on top of a network is ever changing, and the success criteria for the ways we use the Internet is also constantly changing. New metrics like responsiveness are being developed and rolled out to help track these new criteria. Being able to make sure that users have a good experience on your network no matter what is critical for customer retention and cost efficiency. If people have a good experience, they’ll keep using your network. And if people have a good experience, they won’t call support and try and get things fixed.

We are proposing a framework and data set that will not only give you insight into what applications consider success, but ways to programmatically detect when users in your network are experiencing degradations from success: Aggregated Internet Measurement

Full Abstract

Mapping Autonomous Systems (AS) to the owner organizations is critical to connect AS-level and organization-level research. Unfortunately, constructing an accurate dataset of AS-to-organization mappings is difficult due to a lack of ground truth information. CAIDA AS-to-organization (CA2O), the current state-of-the-art dataset, relies heavily on Whois databases maintained by Regional Internet Registries (RIRs) to
infer the AS-to-organization mappings. However, inaccuracies in Whois data can dramatically impact the accuracy of CA2O, particularly on inferences of ASes owned by a same organization (sibling ASes).

In this work, we leverage PeeringDB (PDB) as an additional data source to detect the potential errors of sibling relations in CA2O. By conducting a meticulous semi-manual investigation, we discover the sources of inaccuracies in CA2O are two pitfalls of Whois data, and we systematically analyze how the pitfalls jointly influence the CA2O. We also build an improved dataset on sibling relations, which corrects mappings of 12.5% of CA2O organizations with sibling ASes (1,028 CA2O organizations, associated with 3,772 ASNs). To make the process more scalable, we design an automatic approach to reproduce our manually-built dataset with high fidelity. The approach is able to automatically improve inferences of sibling ASes for each new version of CA2O.
