One Line Summary

Discuss adding stateful features to OVS by leveraging kernel functions

Abstract

Open vSwitch is a full-featured, multilayer virtual switch. It’s traditionally been programmed through OpenFlow, which was originally targeted at hardware switches and built around matching packet headers. New demands have necessitated keeping track of state across packets and flows. In this presentation, we look at leveraging some of the kernel’s features to enable stateful services. We will discuss the best approaches to integrate with the kernel and how to expose those services through a traditionally stateless protocol like OpenFlow. In particular, we will look at connection tracking, NAT, load-balancing, and DPI.
