Linux Plumbers Conf 2013

One Line Summary

Abstract

Over the past few years much of the focus in networking has moved from data centers to the cloud. As a part of this transition we have moved from classical VLAN to more complex tunnel protocols such as VXLAN and NVGRE. While these new protocols allow for greater scalability they also currently result in some performance drawbacks.

This talk will go over the current limitations of VXLAN and NVGRE offloads in terms of performance, will go over what steps have been taken to address some of these issues, and presents further steps that could be taken to further improve the performance of these protocols on existing hardware.
