VANCOUVER, BC — David Ward, Development CTO and Chief Architect at Cisco, has been thinking a lot about how networking works in the cloud era, and he shared some of those thoughts at the OpenStack Summit here.
One of the efforts that Cisco is working on is something that goes beyond the OpenStack Neutron networking project.
"As of recently, Neutron only actually had one virtual forwarding plane that it could operate, and late last year multiple forwarders were enabled, which created a plug-in model," Ward explained. "We have a group-based policy and added OpenDaylight into the entire stack."
When looking to deploy Network Functions Virtualization (NFV), there is a need to deploy a service with an easy way to operate as a service chain.
"Group-based policy is the notion of endpoint groups and the contracts between them, " Ward said. "We invented service function chaining, which passes metadata and context from the forwarding path to be able to direct the application."
Ward added that the combination of group-based policy and service function chaining effectively becomes the business policy for application deployment.
