Preparing Cable for the Converged Future: Casa System’s White Paper

As the cable industry adds mobile access technologies to their service offerings, operators are continuously looking for ways to efficiently deploy new services and optimize capital and operational costs.

Intel, Casa Systems, and Kyrio integrated a proof-of-concept (PoC) system in the Kyrio NFV Interop Lab that gives operators the ability to deploy a virtual Evolved Packet Core (vEPC), virtual Wireless Access Gateway (vWAG) and a virtual Converged Cable Access Platform (vCCAP) on an OpenStack cloud.

This unique combination of vEPC, vWAG and vCCAP running in a single cloud instance gives operators the ability to offer both 4G LTE over small cells and WiFi service with WiFi preferred. These virtual network functions can be deployed alone or in combination and they can be distributed over a virtualized DOCSIS® 3.1 Remote PHY architecture.

The project yielded a number of other positive outcomes. First, the PoC was built on an open source cloud platform, rather than a proprietary one. CableLabs’ SNAPS project (SDN/NFV Application Platform and Stack) is an open source installation package for the OPNFV OpenStack.

Second, the system integration was a multi-party collaborative effort taking advantage of the Kyrio NFV Interop Lab’s infrastructure, test and engineering assets to accomplish a complex virtualization demo in a compressed 8 week time frame.

Finally, the PoC received a high degree of visibility in the cable industry resulting in operator engagement and lab trials for the associated solution providers, demonstrating the industry’s growing interest in virtualization and CableLabs and Kyrio’s role in facilitating the adoption of the technology.
