Cisco Launches Total Solution for Global Cable Access Networks!


The demanding needs from consumers to cable operators across the world has been broadband infrastructure that would be capable of supporting newer applications such as OTT streaming video and 5G mobile back-hauls. Now, Cisco today announced the industry’s first fully automated ‘Infinite Broadband’ remote PHY solution which enables, open, virtualized networks, for Cable Access networks! The Remote PHY (RPHY) and DOCSIS® 3.1, two CableLabs standards, all work together to expand capacity of the cable HFC plants. Building on the Cisco® cBR-8 converged broadband router and GS7000 node platforms, RPHY allows for a reduction of power, cooling and hub site sizing, providing significant total cost of ownership (TCO) benefits. It is the foundation for Cisco’s virtualization and Full Duplex DOCSIS strategy.

The open source solution (RPHY), is standardized software which invents a true landscape of Remote PHY device vendors that allows for the operator to best select their own solutions, without being locked into a single vendor’s proprietary solution!  “Remote PHY is an exciting innovation, and as we continue to evolve our network to provide the best broadband experience to our customers, we are looking to leverage technologies such as this that support our goal of building a distributed, intelligent, IP-based architecture,” said Dr. Robert Howald, vice president, network architecture at Comcast Cable.

The RPHY has been shipping to customers around the globe since last month (April 2017). The deployment of Cisco’s RPHY automation software is based on the model-driven network configuration protocol (NETCONF) and YANG technology and it has been the result of significant savings over the current manual provisioning solutions that are in place today. “We’ve seen huge success with our cBR-8 platform after just two years,” said Sean Welch, vice president and general manager, Service Provider Infrastructure Group, Cisco. “RPHY is the next step in the evolution to an all-IP network that is faster, more scalable, and simpler to operate. RPHY provides a foundation for further network evolution, such as Infinite DOCSIS and Cloud Native technologies, allowing our customers to reduce the total cost of ownership, while keeping their cable networks competitive for the future.”

*Cisco is also planning to provide for interop testing between these OpenRPD vendors using a third-party testing facility. Among the companies planning to participate in the test are VECTOR Technologies, BKtel networks, Teleste and others.
