0x14: Talk Accepted, Test Your Limits With TRex Traffic Generator
by Jamal Hadi Salim 19 Jan '20

19 Jan '20

The Program Committee has accepted another nutsnbolts talk. So you have 100Gbps port and you want to do high performance network testing for your shiny new Linux kernel feature.... Folks, your options are pretty much limited to expensive, commercial equipment(we are talking hundreds of thousands of $$). Or you could use Trex. Come and hear Hanoh talk about Trex. Trex leverages COTS x86/ARM servers and most modern physical NICs. What can Trex do for your perfomance testing? - generate upto 200gbps/100mpps advance traffic pattern - millions of real world tcp/udp flows both stateful and stateless for testing packet forwarding and end servers. - Millions of Connection/s (CPS) for flows - etc Hanoh will share the experiences they gained when writting Trex that apply to scaling Linux networking; he hopes to inspire some of the techniques to be adopted in Linux.

0x14: Talk Accepted, Evaluating BBRv2 on the Edge
by Jamal Hadi Salim 18 Jan '20

18 Jan '20

The Program Committee has accepted another nutsnbolts talk. Alexey Ivanov will discuss evaluation of TCP BBRv2 on the Dropbox Edge Network. Alexey will dissect BBR design principles and discuss whether the intended theoretical goals match real world results. He will then dig into the BBRv2 design and discuss the intended improvements over BBRv1. Eventually, using practical examples, compare the behaviors of BBRv2 vs BBRv1 vs CUBIC as applied to an edge network.

0x14: XDP and the cloud: Using XDP on hosts and VMs
by Jamal Hadi Salim 17 Jan '20

17 Jan '20

David Ahern will give a tutorial on integrating XDP in a cloud deployment with VMs and containers. The tutorial will interactive with source dissection and live demos (with the source code available later from github). David will look at the current state of XDP through the lens of cloud hosting, discussing the advantages, trade-offs, and limitations of using XDP on the host with the v5.4 kernel (latest LTS). This tutorial covers: - configuration of the host, - walks through an L2 forwarding program, - management of the fdb and device maps using bpftool, - simple per-VM/container ACL via eBPF, - XDP forwarding in the egress path, and - using XDP in VMs running on the host.
