Talk: "Virtual switch HW acceleration" (Rony Efraim)

Submitted by admin on Tue, 01/26/2016 - 13:53
Description:

Software based switching consumes CPU resources that can instead be offloaded to modern network adapters.

In this talk we propose switch acceleration where functionality is done by software and when possible/sensible to offload to HW utilizing the switchdev framework when possible. Our approach can be implemented using existing functionality of most modern NICs that already support packet classification, multiple send and receive rings, traffic shapers and L2/L3/L4 overlay networks encapsulation / decapsulation.

Talk: "Challenges in Testing - How OpenSourceRouting tests Quagga" (Martin Winter)

Submitted by admin on Sun, 01/17/2016 - 12:12
Description:

The talk gives an overview on how NetDEF/OpenSourceRouting tests the Quagga projects and discusses some of the challenges. In the talk we’ll go into the details on how we (as OpenSourceRouting) tests Quagga and the challenges we have with a multiplatform tool, supporting many different OS variations, CPU architectures and a community of various volunteers and commercial users. The goal of the talk is to give some inspiration to other projects on how to approach this and start a discussion.

Talk: "HW High-Availability and Link Aggregation for Ethernet switch and NIC RDMA using Linux bonding/team" (Or Gerlitz, Tzahi Oved)

Submitted by admin on Sat, 01/16/2016 - 13:51
Description:

The Linux networking stack support High-Availability (HA) and Link Aggregation (LAG) through usage of bonding/teaming drivers, where both set a software netdevice on top of two or more netdevs.

Those HA devices are set as "upper" devices acting over "lower" devices. The core networking stack uses notifier mechanism to announce setup/tear-down of such relations.

We show how to take advantage of standard bonding/team and their associated notifiers to reflect HW/LAG into HW and achieve enhanced functionality.

Talk: "nftables switchdev support" (Pablo Neira Ayuso)

Submitted by admin on Fri, 01/15/2016 - 12:00
Description:

This talk covers the design and implementation of the nftables switchdev support. The goal is to introduce the audience to the new in-kernel infrastructure to represent the rulesets through a generic abstract syntax tree that can be easily transformed from the drivers into the hardware specific representation.

Talk: "On getting tc classifier fully programmable with cls_bpf" (Daniel Borkmann)

Submitted by admin on Thu, 01/14/2016 - 10:57
Description:

In this talk/paper, we provide a technical deep-dive into the eBPF architecture, comparing it to the classic BPF framework and how tc's (traffic control) packet classification in the kernel is making use of it.

The talk will discuss recently upstreamed features to the kernel and iproute2 and walk through some examples on how classifier/actions can be programmed in restricted C and loaded into the kernel on ingress/egress side with the help of llvm and tc. It'll also cover the topic of sharing eBPF maps and working with eBPF tail calls.

Tutorial: "nftables from ingress" (Pablo Neira Ayuso)

Submitted by admin on Wed, 01/13/2016 - 13:27
Description:

nftables was merged to Linux kernel 3.13, being announced as an ongoing development effort to overcome the existing limitations of the popular {ip,ip6,arp,eb}tables userspace tools and the xtables kernel framework.
