China Mobile, Huawei Propose Cloud BNG Protocol

The China Mobile Research Institute and Huawei have submitted a proposed standard for the first cloud-based broadband network gateway (BNG).

The submission with the Internet Engineering Task Force (IETF) includes proposed control plane and user plane separated protocol (CUSP) requirements for cloud-based BNG interfaces.

The CUSP draft defines protocol requirements for information delivery, reliability, and security mechanisms needed for communication between the control and user planes in cloud-based BNG architecture with separated control and user planes, Huawei said in a statement.

At the 100th meeting of the IETF, Huawei and China Mobile presented the CUSP draft and information model, inspiring discussions on the dynamic control plane concept and methods to separate the control and user planes. 

“The CU-separated BNG architecture allows network resource pooling to improve resource utilization and enables centralized virtual control plane to accelerate service efficiency and shorten new service provisioning time,” said Hu Shujun, an expert at the China Mobile Research Institute. 

“These are the business values brought by the architecture. The standards proposal submitted at the meeting was well received by industry experts, and the interface protocol and information model for interaction between the control and user planes will drive the new architecture to mature and become applicable."
