Service Function Chaining and OVN- Louise Fourie and Farhad Sunavala, Huawei; John McDowall, Palo Alto Networks; and and Flavio Fernandes, IBM

Sign up or log in to save this to your schedule and see who's attending!

The ability to dynamically to create and modify service chains of multiple virtual network functions is a critical component enabling the deployment of network function virtualization.


This presentation will show how service function chaining may be added to OVN and how it may be integrated with OpenStack networking service function chaining. It will cover the details of extensions to the OVN schema, the OVN logical flow model, nb-ctl commands. The OVN driver for Neutron networking-sfc will also be described.

While OVN SFC is CMS agnostic, the combination of the OVN and OpenStack SFC will enable the delivery of advanced service chaining use cases with a standard Openstack interface and implementation.

We will provide a short demo to show our initial implementation of SFC in OVN, and go over the future work items in this area. We are very much interested in fostering participation and feedback from folks who use SFC.
