0x12: Moonshot talk! Composing and configuring complex network interfaces on NICs that contain a switch
by Jamal Hadi Salim 12 Jun '18

12 Jun '18

New Moonshot talk accepted! With the emergence of switchdev as the canonical NIC-switch representation comes the view that we need to expose each switch port as a singular netdev. There is, however, an impedance mismatch between that model and a few important use cases. Take for example the need to scale performance of high speed ports; where a reasonable approach is to spread a single NIC-switch port's traffic across multiple PCIe devices. A single netdev representation doesnt cut it for that scenario. There are other use cases of which involve hierarchies of VMs/containers where more of these issues emerge - for these use cases there have been discussions to use 2 or 3 netdev layers; however, even there some challenges emerge. Anjali Singhai Jain and Sridhar Samudrala make the arguement that the switchdev port representor as is is not the best fit for these use cases. In this talk they are putting forth a proposal that they feel will cater to various use case needs while maintaining strong control over the resources proposed by the switchdev model.

0x12:Keynote Speaker - Van Jacobson
by Jamal Hadi Salim 07 Jun '18

07 Jun '18

We are pleased to announce our Netdev 0x12 keynote speaker: Van Jacobson For most people involved in the networking world, Van will need very little introduction for his work, amongst many, in TCP/IP network performance and scaling of the internet. For the young lads amongst us who may be oblivious of his accomplishments, Van is what you folks typically refer to as a G.O.A.T(Greatest Of All Time) and some of us would refer as a living legend[1]. A few of his accomplishments are listed on his Internet Hall of Fame Induction bio: https://www.internethalloffame.org/inductees/van-jacobson This announcement space is too small for us to enumerate his many accomplishments and current passions - but we wanted to highlight one buzzword in particular: You would not have EBPF today if Van was not there[2]. At the moment Van is involved, at Google, in a passion of his - Network Performance Scaling. Having Van at this conference is both a privilege and an honor as he has seen a lot of ideas take wing from the early days of the internet to the specialized roles around Data Center, Web, IOT and more that we see today. We wish to learn from this sage. To paraphrase European Communication Magazine[3]: "When Van Jacobson has something to say, people listen." And Van has something he wants to say to us at Netdev conf 0x12: We need to teach Network Interface Cards about time. What kind of surgery do we need on the kernel NIC interfaces? What kind of features do NIC vendors need to provide? Come and listen to Van. cheers, jamal [1]https://www.merriam-webster.com/dictionary/living%20legend [2]http://www.tcpdump.org/papers/bpf-usenix93.pdf [3]https://www.eurocomms.com/features/analysis/8238-could-content-centric-ne…

0x12: Moonshot talk! Restructuring Endpoint Congestion Control
by Jamal Hadi Salim 05 Jun '18

05 Jun '18

New accepted talk. From the same folks at MIT who brought you the idea of Congestion Manager (Linux being able to plugin different congestion control algorithms) comes an exciting(my emphasis!) idea to bring even more modularity into Linux TCP. CM concepts that were harder to put into the kernel are now possible. Akshay Narayan et al discuss Congestion Control Plane (CCP). CCP is a new way of separating sender side TCP into control (sitting in user space) and datapath (sitting in the kernel). Control state from the kernel is used by algorithms in user space. User space algorithms use this information to control the kernel’s congestion window or pacing rate. The talk will describe the details of the design principles used, kernel refactoring made, libccp which exposes user API, and experimental results from the implementation.

0x12: Nuts-n-bolts Talk! Identifier Locator Addressing under the hood
by Jamal Hadi Salim 01 Jun '18

01 Jun '18

New accepted talk. ILA has come a long way since the netdev 0.1 days. In this talk, Tom Herbert provides an overview of the ILA protocol, motivation and use cases. He will further provide an update of protocol standardization efforts and then explore ILA implementation internals of both kernel and user space. Finally Tom will run a demo of a simulated RAN-in-a-box.

0x12: Nuts-n-bolts Talk! CogNETive - Smart Network Analytics with Skydive BPF monitoring
by Jamal Hadi Salim 31 May '18

31 May '18

New accepted talk. Liran Schour and Eran Raichstein discuss using the Skydive[1] eBPF filtering capabilities and networking information to create network analytics/insights with their tool CogNETive. They are going to show how CogNETive utilizes the collected information to provide operational insights for network troubleshooting (eg anamoly detection). In their talk they will demonstrate how operators can drill-down on connectivity issues all the way to a single Linux interface. CogNETive uses several common open source components (Grafana, ElasticSearch, Spark etc ...) to create a layer of network analytics on top of Skydive. More info at:https://www.netdevconf.org/0x12/session.html?cognetive-smart-network-ana… cheers, jamal Again reminder: 1) Early bird (20% off) registration fees ends after tomorrow. 2) We do have bursaries for folks who need help getting to the conference.Closes on June 20th.
