OpenStack SDN With OVN (Part 2) - Network Engineering Analysis

In this post we will see how OVN implements virtual networks for OpenStack. The structure of this post is such that starting from the highest level of networking abstraction we will delve deeper into implementation details with each subsequent section. The biggest emphasis will be on how networking data model gets transformed into a set of logical flows, which eventually become OpenFlow flows. The final section will introduce a new overlay protocol GENEVE and explain why VXLAN no longer satisfies the needs of an overlay protocol.

OpenStack SDN With OVN (Part 1) - Build and Install

This is a first of a two-post series dedicated to project OVN. In this post I’ll show how to build, install and configure OVN to work with a 3-node RDO OpenStack lab
