Abstract: Systems and methods presented herein provide for a software defined network (SDN) controller in a cable television system that virtualizes network elements in the cable television system to provide content delivery and data services through the virtualized network elements. In one embodiment, the SDN controller is operable in a cloud computing environment to balance data traffic through the virtualized network elements. For example, the SDN controller may abstract Layer 2 Control Protocol (L2CP) frame processing of the network elements into the cloud computing environment to relieve the network elements from the burdens of Ethernet frame processing. In this regard, the SDN controller comprises a L2CP decision module that determines how L2CP should be processed for the network elements in the cable television system.
