SoftBank deploying Cisco SRv6 network

Cisco is collaborating with SoftBank on the world’s first Segment Routing IPv6 (SRv6) deployment. With the anticipation of the coming 5G era, Cisco has been assisting SoftBank to deploy an SRv6 network nationwide to build a future network architecture that is extremely scalable, with improved reliability, flexibility and agility, all while helping to reduce capex and opex. Current mobile networks are deployed as divided networks, with several layers and complicated control plane processing, which makes it difficult to respond to strict quality requirements like in the case of 5G. Deploying SRv6 in a 5G mobile network aims to simplify network layers and integrate user plane functions from end-to-end with only IPv6 protocol.“Converging 5G features into the end-to-end IPv6 layer with Segment Routing capabilities, is the key to embodying 5G in a simple, scalable architecture,” SoftBank CTO Junichi Miyakawa said.
