Optimization of the resident agent for handling mobile IP MPLS (multi protocol label switching static).

摘要

"The optimization of resident agent for handling mobile IP and static label switched paths.For optimized routing of IP, the invention refers to a resident agent and method for transferring an IP packet on a route from a sender (CN) of a radio access network (RAN), ha, FA, 11) for a mobile host (MS 2) in which.When an agent resident (HA) receives a data packet that is determined for a mobile host (MS (2) with a destination address (address MS 2: 137.21. 16. 5) the resident agent (HA) examines if there is a correspondence between the destination address (address MS 2: 137.21. 16. 5) the package and an address of the subnet address (FA 11: 137. 21. 16.0) of a foreign agent (FA 11) stored in an address list of sub network (137.21.16.0; 137.22.25.0) stored in a list in the resident agent (HA), in which, the correspondence between the destination address (address MS 2: 137.21. 16. 5) and an address of the subnet address (FA 11: 137. 21. 16.0) of a foreign agent, the agent resident examines whether a path pre configured from the resident agent (HA) to the foreign agent exists, and in which the agent resident (HA) sends the packet to the foreign agent (FA 11) in pre configured label switched path (37) ) if a path label switched (37) to this foreign agent exists.
