BRAS is used to authenticate, authorize and route broadband subscriber data traffic according to customized policies. Traditionally BRAS equipment is expensive and implemented with dedicated silicon platform, which is often vendor-locked. The presentation will show virtualized BRAS(vBRAS) solution that runs on COTS. It includes below key elements: 1) A solution framework with separated Control Plane and Data Plane. Control Plane leverages OpenBRAS, an open source project initiated by China Telecom, and Data Plane leverages VPP and DPDK. 2) An advanced flow steering technique to distribute PPPoE packets on a standard NIC to multiple queues, hence handled by multiple cores evenly. 3) ACL and rate limiting is used for uplink flows and Hierarchical QoS(HQoS) for downlink flows.
