Abstract
The invention relates to a method for routing packets in a system of packet-switched networks comprising a plurality of home agents, at least one mobile node and at least one correspondent node, the mobile node having at least a first home address and communicating with the correspondent node over a first of the plurality of home agents. The method comprises the following steps carried out by the mobile node: receiving an application layer request message from the correspondent node; looking up a correspondent node address in a part of the application layer request message; locating a second of the plurality of home agents in proximity to a direct path between the mobile node and the correspondent node using the correspondent node address; bootstrapping with the second home agent to obtain a second home address; including the second home address in a part of an application layer response message to the correspondent node to enable the correspondent node to use the second home address for data communications with the mobile node.
