SHENZHEN, China -- Huawei and the China Mobile Research Institute have submitted a standards proposal to the Internet Engineering Task Force (IETF) for the first cloud-based Broadband Network Gateway (BNG) interface protocol requirements. The proposed Control Plane and User Plane Separated Protocol (CUSP) requirements for cloud-based BNG interfaces were delivered at the 100th meeting of the IETF, the international organization responsible for developing Internet standards. The proposal marks an important step towards standardization of CU-separated BNG architecture.

The standardization of interfaces between the control and user planes must be achieved before large-scale commercial deployment of cloud-based BNG architecture can be achieved. 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. It is the industry's first dynamic control plane protocol proposed for BNGs.

At the meeting, Huawei, together with China Mobile, presented the CUSP draft and information model for interaction between the control and user planes. The proposals were well received and inspired discussions on the dynamic control plane concept and methods to separate the control and user planes. Huawei and China Mobile will continue to promote the standardization of these proposals in the IETF Routing Area Working Group (RTGWG).

It is always necessary to pool the efforts of industry chain partners to promote the formulation of standards. To address the challenges faced by legacy fixed broadband services, that is, low resource utilization, complex management and maintenance, and slow service provisioning. China Mobile and other operators have proposed innovative CU-separated BNG architecture and are actively promoting its standardization through joint innovation.

"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. On the way to standardization of this architecture, we are open to new thoughts and welcome conversations with more industry experts to accelerate this process."

Huawei has also speeded up development of the cloud-based BNG solution design based on the CU-separated BNG architecture. In March 2017, Huawei worked with the European Advanced Networking Test Center (EANTC), an internationally recognized independent test center, to complete the industry's first function and performance tests on broadband access for one million home subscribers. In June, Huawei and China Mobile Shaanxi successfully carried out the world's first commercial trial of the CU-separated BNG architecture on a live network.

Looking to the future, Huawei will work closely with operators around the world and continuously innovate in CU-separated BNG architecture standards to promote cloud standards formulation for all cloud transformation of metro networks. This will unleash the potential of metro network and ultimately help carriers achieve digital transformation and business success.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
