Abstract

This invention relates generally to a method of associating an IP address with a link layer address in a wireless communication network. The method comprises the steps of assigning an IP address to a plurality of link layer addresses; establishing a link layer connection with a first wireless network interface on the IP address; and establishing a link layer connection with a second wireless network interface on the IP address. The method of the present invention enables the increased downloading of data to a client device by aggregating data links associated with an IP address. The method also enables the bi-casting of data to a client device from an IP address associated with a plurality of link layer addresses of wireless communication device. Finally, the invention enables failure recovery by enabling downloading to a second link layer address if a communication link to a first link layer address deteriorates.

Claims (10)

1. A method of associating an IP address with a plurality of link layer addresses in a wireless communication network, the method comprising the steps of:

assigning an IP address to the link layer addresses;

receiving from a router a neighbor advertisement message having a bit flag indicating that the router is capable of processing multiple link layer connections with a client device under the same IP address;

responding to the router providing the link layer addresses and a weight vector indicating, for each link layer address, the weight vector to be assigned in a connection to be established using that link layer address;

establishing a first link layer connection with the router using a first wireless network interface assigned to a first one of the link layer addresses on said IP address;

establishing a second link layer connection with the router using a second wireless network interface assigned to a second one of the link layer addresses on said IP address; and

communicating data through the router using the first and second link layer connections in accordance with the weight vector.

2. The method of claim 1 , wherein the first and the second link layer connections support point-to-point connections with a second communication device and a third communication device, respectively.

3. The method of claim 1 , wherein the first and the second link layer connections support a point-to-point connection with a second communication device.

4. The method of claim 3 , wherein data communicated over the first and second link layer connections are aggregated.
