ZTE has launched the ZTE ElasticNet, a Software-Defined Networking (SDN) based IP-RAN solution to bring virtualization to the access-layer equipment, simplifying network structures and operations and maintenance (O&M) and offering an intelligent, maintainable IP-RAN bearer network.
According to ZTE, the ElasticNet SDN IP-RAN uses an external stand-alone controller to quickly respond to and follow the development of SDN technology. It also uses the standard Openflow protocol and is compatible with other vendors for cross-vendor service deployment, complying with SDN concepts and development trends.
The management of IPRAN solution that typically runs on IP/MPLS (internet protocol/multi-protocol label switching) with layer 3 routing protocols such as IGP/BGP/LDP/TE/PW/BFD involves a large number of nodes which require the new management tools.

With the growing popularity of mobile Internet, mobile bearer networks are taking on an increasingly important role, and meanwhile higher labour costs are creating more pressure for efficient network operation. Applying SDN to the IPRAN combines software-based automatic management and application-on-demand to help operators further simplify O&M and enrich service capabilities so as to provide customers with better service.
