The ability to dynamically create and modify service chains of multiple virtual network functions (VNF) is a critical component enabling the deployment of NFV. Until recently this ability has required add-on SDN controllers with third party neutron plugins, resulting in a patchwork of solutions.
The Openstack networking-sfc has created a standard service chaining interface and an extensible driver model to enable different networking technologies to provide service chaining and flow classification. The networking-ovn project, which everages the OVN enhancements in OpenVSwitch, has introduced a new highly scalable networking infrastructure for Openstack. The combination of these Openstack projects will enable the delivery of advanced service chaining use cases.
This presentation will show how advanced service chaining use cases can be delivered at scale by using these new Openstack components.
The presentation will cover the details of the networking-sfc driver model, how it integrates with networking-ovn and OVS/OVN to provide a distributed and scalable service chaining implementation . The presentation will include a demo of an advanced service chaining use case "secure micro-services" that now becomes possible with the front-end OpenStack SFC interface and the back-end OVN implementation.
