The Open Source Network Operating system landscape changed over the last few years and has been gaining increased adoption at hyper-scalers, service providers and large enterprises. In this talk I attempt to simplify what really makes up a network operating system at a high level, highlight and provide an overview of some of the prominent open networking operating systems, components and tools that are out there now and in the works, their current state, features supported, use cases where these can be deployed and what's next.

Full Abstract

Akamai is leading a standards-based open access approach to interdomain multicast. We're now at the stage of seeking partners to help us validate and refine the architecture, to make sure it will work well for operators. This talk covers our motivations in pursuing multicast IP, a brief overview of the key pieces of the proposed architecture, and invites participation to operators who would like to join us in making it happen.

Full Abstract

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, the visual display of information, and improvisational acting.

In this tutorial, the attendees will learn 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.

This presentation looks at IPv6 adoption over Internet Exchanges. It looks at IPv6 peering availability on Internet exchanges globally and how IPv6 looks on the exchanges compared to the Internet in general. Because Hurricane Electric is present at over 230 exchanges, we are in a unique position to see this data and share it with the community. The presentation includes detailed graphs of IPv6 peering on individual exchanges and looks at how exchanges are influencing IPv6 adoption.

The United States Government Office of Management and Budget recently announced a memo that directed all agencies to plan for at least 80% of IP-enabled assets on Federal networks to be IPv6-only by the end of FY 2025. This is the first of what will mostly likely be several announcements about network operators moving to IPv6-only networks. As we move to IPv6-only networks operators are looking for ways to help with the transition customers. The IETF has documented several different protocols for this transition which includes MAP-E, MAP-T, DS-Lite, LW4over6, and 464XLAT. These protocols allow for network operators to roll out IPv6-only networks in pieces instead of all at once.

When deploying new protocols into the network, operators need to ensure that devices can interoperate. Developers of the products need to ensure the network devices they are developing meet the requirements of the standards and the network operators.
Both network operators and developers need testing to ensure transitioning to IPv6 networks will have a low impact on the users. Current testing for both Interoperability and Conformance has shown common issues that the community can learn from including fragmentation, configuration, and protocol complexity that can be avoided. This presentation will present the lessons learned during testing of IPv6-only transition technologies.

This talk will explore some of the many times that the Internet has been declared dead, claimed to be useless or about to be replaced by some other network that will meet our every need. Needless to say, the Internet has not been replaced
and has survived all these “deaths”. Examining these cases can teach us something about how non-netheads view the Internet and give us a heads up on what might be on the horizon and coming this way.

Full Abstract

Since 1984, the .ORG domain has been the home of non-profits, families, projects and hobbies, and all the other noncommercial odds and ends that make the Internet more interesting than just a bunch of companies trying to sell you more junk. In November of last year, ex-ICANN-CEO Fadi Chehadi tried to borrow $1.135 billion to do a hostile takeover of .ORG, bypassing the multistakeholder and competitive processes which are intended to protect .ORG's registrants.

In this talk, I'll discuss a bit of the history of the .ORG domain and the politics that led to it being in such a precarious position. I'll discuss the specific dangers that .ORG registrants were facing, particularly to their privacy and the operational reliability of the domain and all of the infrastructure (think the Red Cross, the World Bank, the United Nations, and the IATA) that depends upon it. I'll talk about how .ORG registrants organized to fight the threat, and why that fight is a long way from over. This talk will delve a bit into the governance mechanisms that were built into ICANN, and how those have been eroded in the 22 years since its establishment. Finally, I'll suggest a few changes that could protect .ORG and other domains from these dangers in the future.

RPKI deployment practices at Tier 1s

Full Abstract

From recent news: "NTT announced that it deployed RPKI-based BGP Origin Validation on its Global IP Network, starting on 25 March, resulting in the rejection of RPKI Invalid BGP route announcements on AS 2914 EBGP sessions. This change positively impacts the internet routing system."

But... how did we get there? What exactly improved? What does NTT deploying RPKI OV mean for other network providers? What does RPKI mean for troubleshooting? What to consider when deploying RPKI OV in your own network?

Through this talk I hope to share experiences from NTT's RPKI OV deployment.

Full Abstract

This tutorial describes the evolution of IP Fast Reroute (FRR). It covers Loop Free Alternates (LFA), Remote LFA (RLFA), and Topology Independent LFA (TI-LFA).

IP FRR computes a restoration path to be used in case of link failure. When a link fails, the node immediately upstream of the failure shifts traffic to the restoration path, preserving connectivity while routing protocols converge.

Each stage of IP FRR evolution represents an improvement in its ability to support any network topology.

Full Abstract

Network and services monitoring is crucial for quality and security. This can explain the rise of Distributed Measurement Systems (DMS): Devices deployed over networks, embedding monitoring applications periodically testing network and services and retrieving measurements further used for dashboarding, alerting, etc. Examples of DMS range from private infrastructures deployed by ISPs to measure end users « QoE » (e.g. SamKnows, IpLabel, home made) to large scale public infrastructures (e.g. RIPE Atlas, CAIDA Ark) that can be used for Internet Tomography studies.

Designing DMS is challenging especially as they must scale and provide reliable measurements. Especially, when many applications are collocated on the same machines, one has to make sure they do not compete for resources while executing as to not bias the collected measurements. To this end, we propose the NMaaS, an open-source platform, publicly available which enables to deploy and manage containerized measurement applications on a pool of physical machines.

An NMaaS instance is accessible via an online application allowing users to: choose monitoring applications from a pre-defined catalog to be deployed on machines in the network; visualize and manage their pool of machines, as well as the monitoring applications deployed on them; examine the results of the measurements and alerts raised. The first catalog contains: an IP spoofing detection app; a web (resp. streaming) QoS measure app; a web (resp. streaming) cartography app. The goal is then to motivate users to propose new apps to be added to the catalog. Furthermore, we propose and develop a scheduler for our NMaaS solution to make sure monitoring applications do not compete for resources while executing as to not bias the collected measurements.

In terms of implementation, a cluster of Docker containers is provisioned by Kubernetes to orchestrate the deployment of applications across the nodes by following a master-worker pattern. It is automatically set up by Ansible for node scalability, monitored by Prometheus by means of node exporters and sketched by Grafana to give an overview of the platform. Additionally, AlertManager sends notifications whenever an explicit metric reaches a threshold.

As a conclusion, the NMaaS allows rationalizing network and service monitoring, while scaling and ensuring accurate measurements. Gains are numerous: open source and publicly available for the community to use and extend; automation in deployment and use (no need to go on site to deploy new measurement applications making the solution lock down friendly); easy and rapid integration of applications to the platform thanks to the catalog system and its container-based architecture and finally the ACS-based scheduler that enables proper resource allocation. So far, only the platform itself is available, the scheduler and the apps catalog are to be released soon.
