0x16: Keynote Speaker, John Ousterhout
by Jamal Hadi Salim 23 Sep '22

23 Sep '22

We are honored to announce our Netdev 0x16 keynote speaker, industry and academic luminary: John Ousterhout John is the Bosack Lerner Professor of Computer Science at Stanford University with research focuses on new software stack layers to allow datacenter applications to take advantage of communication and storage technologies with microsecond-scale latencies. Amongst his many accomplishments are a few things to note: He is author of the book "A Philosophy of Software Design"[1], co-creator of the Raft consensus protocol[2], and creator of the Tcl scripting language and the Tk toolkit[3]! John says TCP is just plain wrong for modern datacenter technologies. While he acknowledges TCP's perseverance, having survived 40 years of dramatic technology changes, he thinks it's time for us to move on to a new approach that will make headway against what he calls the "datacenter tax". John will enumerate the problems that makes TCP unfit and then will describe his Homa transport protocol approach which tackles the issues with TCP alongside an evolutionary path to retiring TCP altogether. John is one of the rare professors who code ;-> Potential grad students, are you seeing this?. In this keynote he will discuss his experience in implementing Homa in the kernel. Oh, one last thing: He argues that it doesnt make any more sense to implement transport protocols in software - and firmly believes they should be moved to hardware. He feels we need to start rethinking the NIC architecture. Come hear his words of wisdom on this topic. You cant possibly miss this keynote talk, folks! Come one, come all.

0x16: Yet More Workshops and Tutorials!
by Jamal Hadi Salim 20 Sep '22

20 Sep '22

1) Workshop: The Segment Routing over IPv6 (SRv6) Network Programming framework enables a network operator or an application to specify a packet processing program by encoding a sequence of instructions in the IPv6 packet header. The SRv6 Network Programming framework is standardized in IETF RFC8986. In this workshop Stefano Salsano, Reshma Sudarshan and Daniel Bernier will give a community update to the on SRv6 support in the Linux Kernel. They will review the supported SRv6 features, and associated iproute2 extension, starting from kernel 4.10 onwards. They will also provide an update on some new SRv6 features that they plan to contribute to the Linux Kernel. In addition, they will review supported SRv6 features in FRR along with some interesting SRv6 control plane features that they plan to submit to FRR. More Info: https://netdevconf.info/0x16/session.html?SRv6-Network-Programming-in-Linux… 2) Tutorial: The P4 language is gaining very strong industry adoption for packet forwarding aiming to become the standard language for programming the network data plane end-to-end. In this tutorial Salvatore Signorello and Fernando Ramos will introduce you to P4 programming with available open-source software. The tutorial will feature a hands-on component where the participants will learn how to program custom packet processing logic into the Linux kernel through several open-source P4 technologies. https://netdevconf.info/0x16/session.html?Learn-how-to-program-the-Linux-ke… 3) Workshop Jamal Hadi Salim will chair the Traffic Control workshop. Face to Face discussions on different TC topics will take place. Current WAG agenda (subject to update): - New features requests/improvements - Performance - Testing Progress 4) Workshop Alexander Lobakin, Maciej Fijalkowski and Larysa Zaremba Will chair an XDP workshop. Agenda to be updated. cheers, jamal

0x16: More workshops and tutorials!
by Jamal Hadi Salim 20 Sep '22

20 Sep '22

Three more announcements: 1) Workshop: P4 has gained industry-wide acceptance as the offload datapath language of choice and the number of (large) NIC consumers that are now mandating P4 as the way to describe offload datapath they desire is growing. After many years of discussions at netdevconf of getting P4 over TC, it is finally here! P4TC is a kernel-native offloadable and scriptable P4 infrastructure. Anjali Singhai Jain will chair the P4TC workshop with discussions on the current kernel effort to get P4 over TC. The first code release will happen at the conference. Current WAG agenda: 1) Code Release and high level overview 2) P4C compiler Interaction 3) Control-user introspection 4) The CI/CD and automated test infrastructure in use 5) Driver interfaces discussion 6) more topics to be added later. Send requests to Anjali. https://netdevconf.info/0x16/session.html?P4TC-Workshop 2) Tutorial: You may have heard of Landlock as a mechanism for providing unprivileged access control. But do you know how Landlock plays in the networking world? Mickaël Salaün, the Landlock maintainer, will guide you through this hands-on tutorial on how to get there. The Landlock mechanism goes beyond network access-control via firewalls or classical applicatiopn restraining via SeLinux or Appamor. Come learn from Mickaël how to patch network apps to use this exciting feature. https://netdevconf.info/0x16/session.html?How-to-sandbox-a-network-applicat… 3) Workshop Johannes Berg and Kalle Valo will chair the wireless workshop. The current topics include Wi-Fi 7 support and replacement for module parameters. cheers, jamal

by Jamal Hadi Salim 19 Sep '22

19 Sep '22

1) Workshop: Donald Sharp will chair the FRR workshop. A current WAG agenda includes discussions on: - the ongoing work in Segment Routing for both OSPF and ISIS, - RFC compliance in BGP, - continued work on Nexthop Groups - further ongoing dataplane integration work - and review of recent releases and what would people like to see from FRR itself in the future. 2) Tutorial If you are a developer who has been curious about RDMA or simply interested in implementing high-performance communication for applications then dont miss this session. Gurus Roland Dreier and Jason Gunthorpe will walk you through the innards to get you there. More details at: https://netdevconf.info/0x16/session.html?RDMA-programming-tutorial cheers, jamal
