Patent number: 10686665Abstract: 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.Type: GrantFiled: August 11, 2017Date of Patent: June 16, 2020Assignee: Avaya Inc.Inventors: Seetharam V. Rao, Prashantkumar Sthavarmath, Prashanth Kumar, Sunil Menon, Seung Bong Han
