Gainspeed, Juniper Networks and JDSU Show How Virtual CCAP Can Revolutionize Cable Networks

Gainspeed’s Virtual CCAP allows MSOs to increase capacity, enable greater network flexibility and service deployment, implement an all-IP architecture, and substantially reducing required space, power and capital expenses.

Gainspeed, the company redefining how cable networks are built, in collaboration with its Ecosystem Partners including Juniper Networks and JDSU, is the first vendor to demonstrate a comprehensive solution that conforms with CableLabs’ Distributed CCAP Architecture (DCA) description.

CableLabs, the industry’s research and development consortium, is currently documenting several different DCAs as it announced in a recently published article. CableLabs noted that DCAs “provide significant scale advantages and flexible deployment options with support for both DOCSIS 3.0 and DOCSIS 3.1.”

Gainspeed’s Virtual CCAP solution addresses a large number of critical issues facing cable operators including the need to increase network capacity, reduce headend and hub space requirements, and migrate to an all-IP network.

Gainspeed’s Virtual CCAP completely eliminates the physical CCAP by leveraging software defined networking (SDN) and network functions virtualization (NFV) to distribute the CCAP’s functions to other devices and locations in the network. It centralizes routing, control and management in the data center or cloud and pushes the physical layer, DOCSIS processing and RF modulation into the node, deep within the access network

By eliminating the CCAP from the headend and replacing analog optics from the headend to the node with 10 Gbps Ethernet, Virtual CCAP provides cable operators with dramatically lower capital and operating expenses, reduced headend footprint and power requirements, and increased hybrid fiber-coax (HFC) efficiency, reliability and flexibility.

By virtualizing the physical CMTS/CCAP platform and delivering full spectrum DOCSIS support, Virtual CCAP provides the foundation for an agnostic access network, enabling the scalable and cost-effective deployment of gigabit services based on DOCSIS 3.0, DOCSIS 3.1 or Fiber to the Home (FTTH) access technologies such as Passive Optical Networks (PON) and switched Ethernet.

The demonstration, a subset of which will also be shown at the upcoming CableLabs Summer Conference (August 2-5, Keystone, CO), showcased a variety of applications featuring products from Virtual CCAP Ecosystem Partners including:

  •     QAM and IP video delivery with Virtual CCAP
  •     Gigabit services over coax with DOCSIS 3.0 and DOCSIS 3.1
  •     Scaling gigabit services with full spectrum DOCSIS
  •     Simplified field operations with Virtual CCAP

Supporting Quotes:

“DOCSIS channel shipments continue to grow at a rapid rate, indicating that MSOs are ramping DOCSIS bandwidth and services like IP video. As this trend continues, MSOs are clearly looking at alternative approaches, including Virtual CCAP, to scaling capacity beyond simply adding more CCAP ports in the headend.”
— Jeff Heynen, research director for broadband access and pay TV at IHS, Inc.

“The cable industry is in the midst of major changes in the competitive environment, consumer demands, and technological landscape. Gainspeed’s Virtual CCAP allows MSOs to impact all three of these areas by increasing capacity, enabling greater network flexibility and service deployment, implementing an all-IP architecture, and substantially reducing required space, power and capital expenses.”
— Krish Padmanabhan, CEO, Gainspeed

“We’re excited to contribute our market-leading routing technology to the industry’s only Virtual CCAP solution, which will pave the way for the future of cable networks. By fully separating the cable-data plane from the cable-control plane, we’re equipping cable providers with the ability to virtualize the CCAP platform and distribute its functions, dramatically reducing operational burdens such as space and power consumption while simplifying and automating the network.”
— Andrew Smith, distinguished engineer and chief architect for cable MSO networks, Juniper Networks

“In addition to the potential for new test functions, the integration of existing HFC maintenance and troubleshooting capabilities into Virtual CCAP enables the transition to DCA architectures with minimal disruption to the Technical Operations workforce.”
— Jim Walsh, product line manager, JDSU
