Abstract
A connection with a mobile node is established. A registration request is received and a tunnel identifier determined. The tunnel identifier is independent of (i) a home address of the mobile node and (ii) an address of a home agent for the mobile node. The registration request is transmitted to the home agent, and the registration request includes the tunnel identifier. A response to the request is received and, responsively, a connection is activated. Data packets are received from the home agent in response to transmitting the registration request. The data packets include the tunnel identifier. The connection is identified using the tunnel identifier and the packets are routed along the connection.
