Leveraging Openflow In DOCSIS® Networks (2013)

By Chris Donley, CableLabs

Networks are becoming virtualized.

With the launch of new services and new demands on the network, operators are demanding greater flexibility, configuration consistency and control. One set of tools for meeting these demands is Software Defined Networking, specifically OpenFlow.

CableLabs, in partnership with MSOs and technology suppliers, has begun a technical exploration of how MSOs could leverage OpenFlow in a DOCSIS® environment. Our research is considering which subscriber services would see the greatest benefit from OpenFlow and how to architect OpenFlow into the DOCSIS network, specifically at the CMTS.

This paper will present findings from our research, specifically: • Targeted subscriber services enhanced through OpenFlow • Key MSO benefits from the introduction of OpenFlow • An architecture for hybrid Open Flow/DOCSIS networks
