First Claim
1. A method for handoff of a wireless client from a first network device to a second network device in a wired network, the method comprising:
- receiving data from a new wireless client at the second network device;
transmitting a request for a route update for the new wireless client to the wired network;
prior to network convergence for said route update, receiving data traffic for the new wireless client from the first network device and forwarding said data traffic to the new wireless client; and
transmitting context information for the new wireless client from the second network device to other network devices in a proximity group of the second network device.

Abstract
A method and apparatus for handoff of a wireless client from a first network device to a second network device in a wired network are disclosed. In one embodiment, the method includes receiving data from a new wireless client at the second network device and transmitting a request for a route update for the new wireless client to the wired network. Prior to network convergence for the route update, data traffic for the new wireless client is received from the first network device and forwarded to the new wireless client. Context information for the new wireless client is transmitted from the second network device to other network devices in a proximity group of the second network device.
