Wi-Fi services multicast to a subnet in a software-defined network (SDN) are extended. An SDN controller centrally monitors a data plane of a Wi-Fi network. Advertisements for services within a first subnet by an advertising station are forwarded to the SDN controller. Parameters of the service of the advertising station are extracted for storage by performing deep packet inspection on the one or more packets. Queries for services within a second subnet by a querying station are also forwarded to the SDN controller. Parameters of the service of the querying station are extracted for storage by performing deep packet inspection on the one or more packets. The query for service to the advertisement matches responsive to the advertisement parameters compared to the query parameters. Responsive to matching, a set of connection parameters necessary for the querying station at the second subnet to connect to the advertising station at the first subnet is sent.

Facilitating content caching in a local network by using software-defined network (SDN) controller to centrally coordinate data plane behavior. One or more packets forwarded from a component of the plurality of network components is received because no flow has been installed at the component to instruct on how to handle the one or more packets. Responsive to a deep packet inspection identifying a request for external content, a caching server is queried on the local network to determine if the requested content is available locally. A response is received from the caching server that the requested content is not available, and in response, a first flow is installed within the local network to route copies of response packets associated with the requested content to the station. A second flow is installed within the local network to route copies of response packets associated with the requested content to the caching server. A third flow routes subsequent requests for the same content.

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).
