ABSTRACT:
The present invention supports a generalized link-layer address extension for an information packet transmission on an IP mobility system. In the invention, a link-layer address for a node can be communicated in any information packet rather than confined to a specialized message format. The link-layer address can be used in link-layer routing protocols to simplify mobile IP hand-offs and routing, reducing overhead data traffic and allowing more efficient use of network resources.
