ZTE decouples VNFM and NFVO via vBRAS in CTNet2025

ZTE and China Telecom announced that they have completed what they say is the world’s first vBRAS full decoupling test in China Telecom’s CTNet2025 Laboratory.

Based on 3-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.

The test involves vBRAS service functions, performance, reliability and lifecycle management. ZTE used its 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.

China Telecom also used TeleNOS to invoke ZTE VNFM to implement one-button vBRAS instance creation and automatic scaling.

All of this verifies the cross-platform decoupling capability of ZTE’s vBRAS and provide a practical basis for the future large-scale commercial deployments, said Hu Longbin,VP of Bearer Network Product Line at ZTE.

“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,” he said. “The virtualization of BRAS, the vital network element in metro networks, will deeply affect the future network architecture.”
