Abstract: For optimized IP-routing the invention discloses a home agent and method for transfer of an IP packet over a path from a sender (CN) over a radio access network (RAN, HA, FA 11) to a mobile host (MS2), wherein, when a home agent (HA) receives an incoming data packet determined for a mobile host (MS2) with a destination address (MS2-address 137.21.16.5), the home agent (HA) examines if there is a match between the destination address (MS2-address: 137.21.16.5) of the packet and a subnetwork address (FA 11-address: 137.21.16.0) of a foreign agent (FA 11) stored in a list of subnetwork addresses (137.21.16.0; 137.22.25.0) stored in a list at the home agent (HA), wherein, if there is a match between the destination address (MS2-address: 137.21.16.5) and a subnetwork address (FA 11-address: 137.21.16.

Abstract: A computer assisted method processes routing/forwarding information in a network by accessing at least one first data structure having at least one entity per object in addition to routing/forwarding information and by accessing a second data structure, having at least one entity per object in addition to the routing/forwarding information. Each object to be processed in the first and second data structures is accessed using the additional entities. The routing/forwarding information is processed using standardized algorithms optimized in terms of timing.
