ZTE has launched a new virtual broadband remote access server (vBRAS) capable of supporting up to 10 million users simultaneously.
The virtualized solution uses network function virtualization to implement a control/user separated architecture capable of integrating user management functions of multiple BRAS devices.
The solution uses a ZTE-developed cloud database (CDB) to overcome the performance difficulty in massive user data synchronization faced by conventional vBRAS suites.
According to ZTE, traditional BRAS devices are being pushed to their breaking point due to the rapid growth of home broadband users and fast development of new services such as 4K, cloud services and Internet of Things devices.
ZTE said its solution uses cloud computing and distributed processing to increase the traditional BRAS user dialing rate by 10 times, the online rate to over 10,000 pieces per second and the user entry distribution rate to over 40,000 pieces per second.
The control/user separated architecture adopted by ZTE's solution can enable control plane resource pooling and on-demand flexible scaling, meeting carrier-grade reliability and mass session requirements.
To ensure resiliency, when the vBRAS control plane malfunctions users can migrate their services to the control plane of a standby vBRAS without disruption or the need to redial.
So far the vBRAS solution has been trialed in existing networks across 10 provinces of China.
