News Summary:

  • Cisco to help DOCOMO accelerate its 5G business model transformation with converged, programmable, SDN architecture to expand its service offerings 
  • Cisco converged SDN transport technology with network slicing will help DOCOMO meet its future 5G base station facility plan to include 400GE deployments


SAN JOSE, Calif., February 25, 2020 – Cisco today announced NTT DOCOMO, INC. selected its Network Convergence System routers and segment routing technology for network slicing to help optimize its 5G mobile backhaul in preparation for the commercial service. 

Mobile backhaul is the transport network that connects the 5G radio (in the cell tower) to the core network that feeds into the data centers. DOCOMO needed a blueprint for more cost effective transport to meet its future 5G base station facility plan capable of achieving 400 Gigabit Ethernet (GE) speeds.

The transformation to 5G requires a shift to a converged, more programmable SDN architecture capable of delivering all types of services (enterprise, consumer, video, 4G/5G mobile, IoT, etc.) Cisco’s converged SDN transport, with segment routing, is designed for cost-effective mobile backhaul. Cisco Network Convergence System routers are used for massive scale, full programmability, simpler cloud integration and service level agreements. 

 “We are convinced that 5G will bring solutions to solve social issues and revolutionize styles for a better life,” said Dr. Hiroshi Nakamura, Executive Vice President and Executive General Manager of R&D Innovation Division of DOCOMO. “We are co-creating 5G services by working closely with partners in various industries, and providing these services requires the provision of more flexible and reliable networks. We are committed to providing a high-quality network through our ongoing partnership with Cisco. We look forward to continuing our collaboration to transform our business model and opportunities in Japan.”

“The IP network plays a more important role with 5G than ever before,” said Jonathan Davidson, Senior Vice President and General Manager, Cisco Service Provider Business. “Networks have to be automated, programmable and capable of massive scale. Together, DOCOMO and Cisco mapped out the right path for its 5G transformation with a new intelligent, software-defined network. Converging services over a common, trustworthy architecture will reduce costs, deliver new services that span multiple domains, and prepare them for a profitable 5G future.”
