Full Abstract

Flexible Algorithm provides means to create separate topologies in a single IGP. Flexible Algorithm Definition includes, metric type, algorithm and the link constraints and is used to define the topology. Flexible Algorithm is a simple and easy way to solve use cases such as separating routing-planes, constrained TE paths and low latency routing. It uses IGP extensions and no other protocols or controllers are required for deployment.

Segment Routing is getting more and more deployed in production networks now, starting with unicast. As more operators moving or planning to move to SR, those with multicast requirements need to consider what options they have for multicast. This presentation looks at SR principals and corresponding multicast options, with focuses on SR-P2MP, BGP/controller signaling, and integration with seamless inter-region SR and classful BGP transport.

Full Abstract

Attacks on Internet routing are typically viewed through the lens of availability and confidentiality, assuming an adversary that either discards traffic or performs eavesdropping. Yet, a strategic adversary can use routing attacks to compromise the security of critical Internet applications likeTor, certificate authorities, and the bitcoin network. In this paper, we survey such application-specific routing attacks and argue that both application-layer and network-layer defenses are essential and urgently needed. While application-layer defenses are easier to deploy in the short term, we hope that our work serves to provide much needed momentum for the deployment of network-layer defenses.

Jennifer Rexford: Jennifer Rexford is the Gordon Y.S. Wu Professor of Engineering and the Chair of Computer Science at Princeton University. Before joining Princeton in 2005, she worked for eight years at AT&T Labs where she designed tools for network measurement, traffic engineering, and router configuration that were deployed in AT&T's backbone network. Jennifer received her BSE degree in electrical engineering from Princeton University in 1991, and her PhD degree in electrical engineering and computer science from the University of Michigan in 1996. She received the ACM SIGCOMM Award and the IEEE Internet Award, and she is an ACM Fellow, an IEEE Fellow, and a member of the National Academy of Engineering and the National Academy of Sciences.

Russ White - Akamai
Full Abstract

Network designers are often told they should build security in to the network "from day one." Very little work, however, has been done in defining what building a secure network really means beyond filtering packets, protecting network devices, and providing segmentation (or microsegmentation). This presentation takes another look at security in network design, considering how complexity and security are related, and how to think about design decisions from a security perspective.

Russ White: Russ White has scribbled a basket of books, penned a plethora of patents, written a raft of RFCs, taught a trencher of classes, nibbled and noodled at a lot of networks, and done a lot of other stuff you either already know about — or don't really care about. You can find Russ at 'net Work, the Internet Protocol Journal, PAcket Pushers, LinkedIn, and his author page on Amazon.

Full Abstract

A measurement of ROA adoption on routes leading to DNS servers supporting the top of the name hierarchy. The DNS servers include the root zone, the ccTLDs, gTLDs and the reverse map zones managed by the RIRs. Analysis of the adoption measurements starts with the obvious categorizations, such as all, IPv4/IPv6, gTLDs/ccTLDs/reverse map.

Edward Lewis: Edward is a Senior Technologist in the Office of the CTO. Prior to joining ICANN he worked 11 years inside Internet registries of many types - gTLD, ccTLD, sTLD and RIR. He worked for a DNS Hosting company. He co-chaired the original IETF WG that developed EPP. He developed some of the first DNSSEC codebases under the original DARPA contract in the 1990's. Before that, he worked building research networks attached to the NASA Science Internet (one of the three original backbones) and taught Networking courses at the University of Maryland - Baltimore County.

Full Abstract

What is automation without configuration deployment? Well.. it turns out there is a lot to be done, in fact, deploying configuration generally only represents a small fraction of total time and is near all of the risk of automation going wrong. Starting on configuration deployment, can actually slow your progress to configuration deployment as it is difficult to trust a new automated process without historical evidence.

During this 30 minute presentations we will review the reasons to forgo configuration deployment and strategies to do so. Topics such as how to integrate with a Source of Truth, generate configurations from a Source of Truth, building an automated pre & post-check process, and integrating with network management systems. Finally, a pragmatic approach to attacking network automation tasks that will appeal to engineers and executives alike.

Full Abstract

The eXpress Data Path (XDP) is a "hook" in the Linux kernel providing programmability at the lowest layer of the Network Stack (at the device driver layer) and can even be hardware offloaded to programmable devices (e.g. SmartNICs). XDP provides an easy way to perform some parts of DNS handling in the kernel but still have traditional userspace software 'after' that. XDP does not have to replace DNS software in userspace, it can **augment** it.

XDP programs are well suited for dealing with Denial of Service attacks. Furthermore XDP programs can be put to work on an ad-hoc basis on a running system without interruption. We think using XDP to augment an existing DNS service is an exciting new idea, and a great new tool in the DNS operator's toolbox.

In this presentation we will explore how DNS can benefit from XDP with hands-on examples of directly usable running code. We will show how operators can use XDP programs to deal with Denial of Service attacks and/or otherwise tweak their DNS service behaviour.

Willem Toorop: Willem Toorop is a developer and researcher at NLnet Labs. He has a special interest in delivering security and privacy (with DNSSEC and encrypted DNS) to end-users at the edges of the internet. Willem likes working with authors from other Open Source DNS Software and DNS Operators on Open Standards and at hackathons to achieve interoperability of the different DNS software. He also likes doing measurements on the state of the internet and the DNS, in order to provide feedback for operators, and to have a better view of where things can be improved protocol wise and in software. He is passionate about his work and cannot help himself talking, explaining and presenting about it.

Full Abstract

Ahoy mateys. Network automation is burning on as the hot topic and this talk will go into self-driving, self-healing and auto-remediation in light of current automation trends and tooling. If network engineers are pirates, then bad times are afoot as the map is missing. For the evolving journey of humans handing over the drudgery of repetitious and mundane work to automation, we must find a way of navigating the seas of operational hell.

This talk will discuss the problem at large, the mindset and the output of some novel work carried out last year year in the name of becoming a network automation cartographer. You can expect frustration, disbelief and the glowing view of treasure, as the work begins to deliver on its mission.

Technically, this is based on a network operating system with a data store (NETCONF & YANG driven), Terraform, a graph database and lots of experimental code. What I can promise is 30 minutes of not Ansible or Python.

This talk is a modified version of the Irish Network Operator Group (iNOG) 14 session and was titled "Automation without a map".

Full Abstract

With a growing reliance on the internet, content delivery is more important than ever. But how does it work? Does anycast really break the internet? In this talk I hope to share my experiences in building an Open Source Anycast CDN as a highschool student, and provide an insight into how I'm using anycast and open source software for DNS and HTTP content delivery.

Nate Sales: Nate is a student and software developer with a focus on infrastructure and security. He works on many layers of the stack but most often enjoys ensuring packets arrive at their intended destination and writing software to make that job easier. He can be frequently found working on open source networking projects and loves learning new things.

Jordan Holland - Princeton University
Full Abstract

This talk presents nPrint, a standard, packet-based representation of network traffic. nPrint enables machine learning on network traffic without manual feature engineering. We combine nPrint with automated machine learning (AutoML) to demonstrate that nPrint can generate a standard traffic representation across a variety of machine learning tasks and models. We present the design and implementation of nPrint, describe how we integrate it with AutoML, and apply the pipeline to three common network traffic classification problems: operating system detection, device fingerprinting, and application identification. We have implemented and released nPrint as open-source software and encourage exploration of more problems with nPrint. Finally, we have also released nPrintML, which enables researchers to perform a wide variety of traffic analysis tasks without writing any code.
