The ONF announced that Comcast has reached production roll-out of the Trellis Open Source Network Fabric as part of Comcast’s Distributed Access Architecture (DAA) buildout.
Comcast has successfully deployed Trellis in multiple markets, and rollouts are accelerating. By using Trellis, Comcast is delivering improved network scalability and greatly enhanced space and power facility efficiencies in their head-ends. Open source and a white box based ethernet backhaul is integral to Comcast’s next generation access strategy, and Trellis plays a central and essential role in this architecture. The DAA specification calls for an ethernet-based Converged Interconnect Network (CIN), and Comcast is using Trellis in this CIN role.
ONF’s Trellis is the leading open-source, SDN based, multi-purpose spine-leaf switching fabric supporting distributed access-and-edge networks, NFV and edge cloud applications. Trellis leverages the ONOS open source SDN controller, the OpenFlow protocol and white box switches to create a scalable, resilient, cost effective networking fabric.

The open source ecosystem created by ONF has collectively established a new ‘Distributed DevOps’ model through the process of trialing, hardening and deploying Trellis with Comcast.
