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).

Abstract: 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.

Abstract: RF tags using source addresses to locate stations on a Wi-Fi network are secured. An RF location server receives a pseudo source address of an RF (radio frequency) tag from a station. The station obtains the pseudo source address while being within radio range of the RF tag and the station receiving a beacon frame from the RF tag. A source address for the RF tag is looked-up utilizing the pseudo source address, and a specific location for the RF tag is looked-up utilizing the source address. Some embodiments store the locations in association with the pseudo address. Either way, the specific location of the station is identified based on the source address of the RF tag. An action is determined in response to at least the specific location of the station. Information related to the action is sent to the station for output to a user of the station.

Abstract: The present description provides methods, computer program products, and systems for alternative network communication for access point troubleshooting and monitoring. When a station has difficulty initiating or maintaining a connection with an access point, or even when performance is suboptimal, alternative network communication is initiated. The issue can be handled by reporting to a troubled access point for self-correction, or by uploading interrogation commands or code for active correction externally by a station. Further actions can be taken, for example, when a station determines through alternative communication that a troubled access point itself has connection issues to a back end network, the station uses a different access point for reporting up to a network admin. Although Wi-Fi and Bluetooth are described herein, other combinations of wireless protocols are implementable.
