200 GbE network processing with 100 W - or "can I make a chip for that?" (denog17) 25:56

4h ago25:56

25:56

This talk presents how to to offload networking tasks onto dedicated hardware/smartNICs/NPUs (network processing units) - chips, and why this is a great idea.First, we take a look at chips in general - how they are made, integrated into networks, and why time is playing to the advantage of dedicated chips vs. CPUs/software.Then, focus is on how off…

Channelmania! – future proof your DWDM network topology while keeping it flexible for 1.6T (denog17) 24:23

4h ago24:23

24:23

Past approaches for maximizing the data capacity per fiber pair went for running more and more DWDM channels with grid spacings as small as possible. This meant that grid spacings shrank from 200GHz to 100Ghz and then 50GHz with some applications even going for 25Ghz. In recent years the bandwidth per channel kept increasing, as complex modulation …

Forwarding packets at scale - Building a Cloud Data Plane using eBPF/XDP (denog17) 28:07

2h ago28:07

28:07

At Hetzner we’ve historically used an Open vSwitch based data plane for connecting hundred thousands of cloud servers to the network. This has served us well for many years and mostly still does. We have however reached some limitations and wanted to improve scalability, resiliency and flexibility with a more specialized data plane that's tailored …
