0x12: Moonshot Talk! Toward an eBPF-based clone of iptables
by Jamal Hadi Salim 22 May '18

22 May '18

Another exciting moonshot talk. Recently there have been discussions for the replacement of iptables with an eBPF-based approach. In this moonshot talk, Fulvio Risso et al discuss what they feel is needed to make such a transition. Is eBPF ready to replace iptables? Come find out and participate in the discussion. https://www.netdevconf.org/0x12/session.html?toward-an-ebpf-based-clone-of-… cheers, jamal PP: The early bird registration is still on at 20% off regular price.

0x12:Tutorial! Server Migration with TCP_REPAIR
by Jamal Hadi Salim 21 May '18

21 May '18

Another exciting tutorial. Project CRIU works against cruelty on containers. To all you who treated containers like cattle - meet CRIU where containers are treated like pets. Come to this tutorial by Andrei Vagin, Mike Rapoport and Pavel Emelyanov and learn how to show tender loving care to your TCP applications. Learn how to checkpoint a TCP session in one container and restore it on another(possibly different machine). This instructor-led tutorial will start with illustration of a simple TCP application migration code; it will then lead towards demonstrating a more complex example where a container with an active ssh connection is checkpointed on one host and restored on another host (and the connection remains live after the restore). https://www.netdevconf.org/0x12/session.html?server-migration-with-tcp_repa… cheers, jamal PS: The CFS is officially closed as of today. Thanks to everyone who submitted. For those who have not yet been notified of the status of their submissions, rest assured the program committee is working hard and you will get a response. PPS: The early bird registration is still on. After June 1st it goes up.

0x12: Workshop! IoT related MAC layers, header compression and routing protocols
by Jamal Hadi Salim 18 May '18

18 May '18

Stefan Schmidt will chair a working session with face to face discussions on IoT related MAC layers, header compression and routing protocols. In no particular order the agenda would roughly cover: o ieee802154 and 6lowpan subsystem status update for the last kernel releases o Defining a userspace API to configure 6lowpan header compression options o Discuss what needs to be done for an ieee802154 hardMAC extension to the stack o Improve test coverage with hwsim, tdc, scapy & TITAN o Thoughts on software fallback implementations for ieee802154 CSMA and AACK o Thoughts on a LoRa subsystem (with SCHC addition to 6lowpan) for Linux please contact Stefan to request for a slot for the above or new relevant topics. https://www.netdevconf.org/0x12/session.html?workshop-on-iot-related-mac-la… cheers, jamal

0x12: nuts 'n bolts Talk! LSDN - Manage complex networks with ease
by Jamal Hadi Salim 17 May '18

17 May '18

Another exciting talk accepted. In this talk titled "LSDN - Manage complex (virtual) networks in cloud environment with Linux kernel facilities" Vojtech Aschenbrenner et al present LSDN, a tool for effortless management of complex (virtual) networks. Often management of virtual networks has dependencies on complex infrastructure orchestration tooling - encumbered with long running agents like OVS etc. LSDN has no external dependency on any such tools and leaves no agents running thus not only improving usability but also robustness of the operations. The tool relies entirely on the functionality provided by the Linux kernel, mainly on the Traffic Control (TC) subsystem with its recent features. Vojtech will describe LSDN features and challenges faced in its development (and how various kernel and iproute2 issues were addressed); then delve into how to write applications centred around the offered C-library and backends. Vojtech will conclude by talking about the future plans for LSDN. More info: https://www.netdevconf.org/0x12/session.html?lsdn-manage-complex-virtual-ne… cheers, jamal

0x12: nuts 'n bolts Talk! Building a Better NOS with Linux and Switchdev
by Jamal Hadi Salim 15 May '18

15 May '18

Another exciting talk from the program committee Amen to the Whitebox! Whitebox! Whitebox! chants. But the emerging creed of "Open" networking operating systems (NOS) is sadly still plagued with ASIC vendor SDKs and the proprietary and legacy baggage they carry. Vendor SDKs quarks impact control performance and dictate how control and datapath APIs look like. The SDK glue creates undue burden on operational interfaces design: config, debug-ability, and monitoring all suffer just so the NOS can adapt to the many every vendor SDKs. The switchdev and related hardware offload interfaces revolution in Linux have matured over the last few years. They provide a singular, cleaner interface to ASIC features. No different than other hardware offloaded by Linux - the hardware vendor provides a driver and leaves the innovation to the NOS and applications. Shrijeet Mukherjee and David Ahern have been in the dragons den of vendor SDKs and have come out scathed but wiser. In this talk they will discuss typical software architectures for a NOS and introduce a path for transitioning SDK based solutions to Switchdev and related offloads. More info: https://www.netdevconf.org/0x12/session.html?building-a-better-nos-with-lin… cheers, jamal PS: Another reminder, early bird registration (currently 20% off will go up on June 1st).

0x12: Moonshot Talk! Developing and Deploying a TCP Replacement for the Web
by Jamal Hadi Salim 14 May '18

14 May '18

Is TCP - at 44 - too old, slow and has bad habits that cant be fixed? Does shaving a few milliseconds of latency on a web transaction matter that much to call out for a new transport? The new kid on the block, QUIC thinks so. QUIC has been globally deployed at Google on thousands of servers. If you are running chrome as a browser and using YouTube, you are likely using QUIC. Estimates are 7% of the internet traffic is now QUIC. In this talk Jana Iyengar and Ian Swett will provide an overview of QUIC, its motivations and the performance improvements observed at Google. They will discuss performance bottlenecks in Linux kernel UDP that were seen at Google's servers, what was done to overcome them and what work remains to be done in the kernel as QUIC becomes more widely deployed. More info: https://www.netdevconf.org/0x12/session.html?developing-and-deploying-a-tcp… cheers, jamal PS: Another reminder, early bird registration (currently 20% off will go up on June 1st).

0x12: Nuts-n-Bolts Talk! Suricata, an XDP adventure
by Jamal Hadi Salim 10 May '18

10 May '18

The program committee has accepted another exciting talk! Suricata is a widely deployed open source IDS/IPS/NSM. Suricata 4.1 will include eBPF and XDP support. In this respect, Suricata is amongst pioneers to deploy these technologies in a production environment. The journey to get to eBPF and XDP support and remove the cobwebs took about 2 years. Eric Leblond will describe some of the challenges met and how they were addressed to get to production level quality. More info: https://www.netdevconf.org/0x12/session.html?suricata-an-xdp-adventure cheers, jamal PS:- Another reminder that: 1) Registration early bird deadline (before prices go up) is June 1st. 2) We do offer bursaries for attending the conference.
