Active Broadband Networks announced that its Dynamic Broadband Service Manager (DBSM) now incorporates software-defined networking (SDN) technologies. The new SDN controller solution is intended to allow network operators to deploy a software-defined service layer for the common control and active management of broadband services across different types of access networks, including cable, DSL, FTTH and WiFi.Operating as an SDN controller, the DBSM uses the OpenFlow protocol to dynamically activate services and manage subscriber traffic flows through SDN-enabled network elements at the broadband edge. OpenFlow structures communication between the control and data planes of SDN-enabled network infrastructure, and allows the DBSM to directly implement service management policies for control of subscriber traffic flows.
