Huawei has announced a string of new products under its SDN-based mobile backhaul solution LTEHaul. The product releases are an important milestone for the development of mobile backhaul solutions as well as a milestone for SDN innovation in carrier IP networks. Huawei supports software-defined networking (SDN) capabilities through the release of its CX600 series aggregation router, its ATN910 series cell site router (CSR) and U2000 network management system (NMS).
Based on these products, the SDN-based mobile backhaul solution effectively provides plug-and-play, auto service provisioning, smart traffic steering and auto troubleshooting capabilities for a large number of cell site routers. Early tests have shown promising results with service provisioning efficiency improvements of 85 percent and over 50 percent reduction in network alarms.
As a result of the exponential growth of mobile broadband, current mobile backhaul networks face many challenges, including complex O&M for the massive scale of cell sites, time-consuming service provisioning and inefficient network utilization. The SDN-based mobile backhaul solution is well positioned to address these challenges, and it’s the outcome of a joint innovation project between Huawei and the China Telecom Guangzhou Institute.
The SDN-based mobile backhaul solution is based on existing network hardware while new SDN features can be enabled through software upgrades; both leveraging and protecting existing customer investments by maximizing existing resources. This solution supports star and ring topologies, further protecting investments in existing deployment topologies and offering flexibility for new deployments.
Huawei has been proactively participating in international SDN standardization efforts, including the Open Networking Foundation in collaboration with stakeholders such as operators, equipment manufacturers and research institutions, to promote the application of SDN in end-to-end networks.
