ZTE Corporation and China Telecom have completed the world’s first vBRAS full decoupling test in the CTNet2025 Laboratory of China Telecom. Based on three-layer decoupling, the full decoupling further decouples NFVO (network functions virtualization orchestration) from VNFM (virtual network function manager) to implement integrated deployment and orchestration of multiple vendors and multiple VNFs, thereby promoting the development of the new industry ecosystem.

The test involves the items of vBRAS service functions, performance, reliability, and lifecycle management.

As a key partner in vBRAS innovation, ZTE uses its flagship product ZXR10 V6000 vBRAS to complete the cross-connection test with all virtualized cloud platforms from other vendors. It also finishes the connection with TeleNOS (Telecom Network Orchestration System), the NFVO system developed by China Telecom Beijing Research Institute to achieve the decoupling of VNFM and NFVO. Besides, China Telecom uses TeleNOS to invoke ZTE VNFM to implement one-button vBRAS instance creation and automatic scaling. All these achievements verify the cross-platform decoupling capability of ZTE’s vBRAS and provide a practical basis for the future large-scale commercial deployments.

“Full decoupling refers to the decoupling of VNF layer, virtualization layer and hardware layer, as well as the decoupling of VNFM and NFVO, which is considered as a big difficulty and the key to NFV deployment. The virtualization of BRAS, the vital network element in metro networks, will deeply affect the future network architecture. We believe ZTE’s ZXR10 V6000 vBRAS has well displayed its technical strength in this test and will help China Telecom promote the metro network virtualization transformation in its CTNet2025 strategy.”
