Huawei and China Mobile Develop SDN Clock Sync

Huawei and China Mobile introduced a software-defined clock metwork solution which provides centralized control and automated management of clock synchronization for mobile backhaul networks.

Huawei said the jointly developed solution automatically computes, plans and provisions the clock paths based on the overall physical network topology, and can thus eliminate the risks associated with manual planning. The embedded algorithm can compute and plan a clock network with tens of thousands of nodes in a few minutes, with the guarantee that synchronization loops will not be introduced. When compared with traditional, manual planning, the efficiency output of the Software-defined Clock Network solution is almost a thousand times better. In addition, the solution also provides performance monitoring, fast assessment, intelligent optimization and rapid trouble-shooting when deployed. Overall, the solution greatly enhances the ability to manage a mobile backhaul clock network, simplifies the network operation to reduce future issues, and reduces operational costs for telecommunications companies.

Mr. Yang Zhiqiang, Vice President, China Mobile Research Institute, said, "Facing the evolving needs of future services and the operation pressure from large scale mobile backhaul networks, more requirements have been placed on the ability of telecommunications companies to effectively and efficiently manage a clock network. The ability to intelligently manage the clock network through centralized control makes the Huawei Software-defined Clock Network solution highly efficient, agile and reliable. It realizes a smooth evolution from the traditional synchronization network to the Software-defined Clock Network, which is why it has proved extremely useful for China Mobile."

Mr. Zha Jun, President, Fixed Network Product Line, Huawei, said, "By applying SDN technology to the mobile backhaul, the Huawei Software-defined Clock Network solution creatively resolves the difficulty operators face planning and managing clock networks. As the industry’s first solution of its kind, Huawei and China Mobile are leading clock network research and innovation, and remain invested in developing SDN commercial applications and networks."
