ZTE has launched the ZTE ElasticNet SDN (software-defined networking) IPRAN (internet protocol radio access network) solution. According to ZTE, the solution introduces SDN virtualization technology to an IPRAN network to virtualize access-layer equipment, simplifying network structures and operations and maintenance (O&M) and offering an intelligent, maintainable IPRAN bearer network.

ZTE’s ElasticNet SDN IPRAN solution virtualizes remote access-layer equipment into the boards of convergence-layer equipment, and convergence/access layer equipment forms a large virtual cluster system. The IPRAN solution is based on unified standard SDN northbound and southbound interfaces to help ensure an open network capability. It uses the standard Openflow protocol and is compatible with other vendors for cross-vendor service deployment, complying with SDN concepts and development trends.

IPRAN is widely used in mobile network backhaul to bear 2G/3G/LTE and other mobile services, using the IP/MPLS (internet protocol/multi-protocol label switching). After the access layer introduces layer 3, IGP/BGP/LDP/TE/PW/BFD configuration takes place.
