Converged wireless local area network

摘要

One embodiment of the present invention provides a wireless network controller. The wireless network controller includes a data structure, a tunnel management scheme, an encapsulation mechanism, and a forwarding mechanism. The data structure stores a TRILL RBridge identifier associated with a remote wireless network controller. The tunnel management mechanism maintains a tunnel with a local access point, and the encapsulation mechanism encapsulates a packet received from the tunnel with a TRILL header which includes the RBridge identifier of the remote wireless network controller. The forwarding mechanism forwards the encapsulated packet.

主权项

1. A first wireless network controller, comprising:
control circuitry configured to store a first media access control (MAC) address and an associated identifier of a virtual local area network (VLAN) of a first end device learned at a second wireless network controller in a first data structure in association with a switch identifier of the second wireless network controller, wherein the VLAN is not locally configured; and tunnel management circuitry configured to maintain a tunnel between the first wireless network controller and a first access point local to the first wireless network controller; and multicast management circuitry configured to:
identify via the tunnel a join request to a first multicast group from a second end device prior to the second wireless network controller identifying a join request to the first multicast group;elect the first wireless network controller for distributing multicast traffic of the first multicast group; andstore in a second data structure membership information of the first multicast group and an identifier of the first access point in association with a switch identifier of the first wireless network controller.
