OpenStack Summit May 2015 Vancouver

OVN is a new network virtualization project that brings virtual networking to the Open vSwitch user community.  It is being developed by the core OVS team.  OVN will support the same container and virtual machine environments as OVS, including KVM, Xen, and Hyper-V. OVN will include logical switches and routers, security groups, and L2/L3/L4 ACLs, implemented on top of a tunnel-based overlay network.  For physical-logical network integration, OVN will implement software gateways, as well as support hardware gateways from a variety of vendors.

The OVN architecture simplifies the current OVS integration within Neutron by providing a virtual networking abstraction.  OVN provides Neutron with improved dataplane performance through shortcut, distributed logical L3 processing and in-kernel based security groups, without running special OpenStack agents on hypervisors.

In this presentation, we will discuss the architecture of OVN, detail our development plans, and provide a demo.  The demo will show an OpenStack-driven OVN deployment connecting containers and Linux and Hyper-V based hypervisors.  We will also discuss how OVN leverages some of the newest features in OVS, which may be of interest to those writing their own OVS control planes.
