Abstract
The present invention relates to the routing of data within communications networks, including but not confined to networks such as the Internet, and particularly, but not exclusively, to a method of routing data directed to a mobile node.
In this invention a protocol is provided which is backward compatible with Mobile IP and Mobile IP with route optimisation. The new protocol uses existing defined messages, utilising unused bits to overcome the problems of triangular routing and tunnelling.
