Abstract:
Wi-Fi flows are intelligently bridged in a software-defined network (SDN) controller of a wireless communication network that centrally coordinates data plane behavior. A default mode tunnels packets received at an access point to the SDN controller for layer 2 routing decisions. A bridging policy concerning bridging of specific types of traffic flows for the wireless communication network is received at the SDN. Data plane traffic flow for each of a plurality of access points distributed around the wireless communication network is centrally monitored. New data streams tunneled to the SDN controller are matched to bridging policies with deep packet inspection. Responsive to matching, the tunnel mode is converted to a bridge mode by sending a rule concerning the new data stream to the access point. As a result, subsequent packets of the new data stream are transferred at the access point without tunneling additional packets to the SDN controller).
