  • Patent number: 10686665
    Abstract: Implementations generally relate methods, systems, and computer readable media for discovery of an open network adapter. In some implementations, a method includes receiving, by a software-defined network (SDN) controller, a notification of an open networking adapter (ONA) establishing a connection with a switch, the ONA having an address associated therewith. The method further includes identifying the switch based on a lookup of the address of the ONA in forwarding tables of a neighboring switch of the SDN controller. The method further includes applying a service profile configuration to a port of the switch where the ONA is connected.

  • Patent number: 9906896
    Abstract: One or more implementations can include methods, systems and computer readable media for client location discovery. In some implementations, the method can include receiving, at an access point, a location discovery request message from a client and sending a request from the access point to a location server requesting location information for the client, when a location server is available. The method can also include receiving location information from the location server, when a location server is available and providing the access point location as location information, when a location server is not available. The method can further include sending the location information as a response to the client.
