Problems solved by technology

[0013] The problem with this current art approach is that the so-called triangular routing is not data transfer efficient because all traffic destined for the mobile node in the foreign network is routed via the home agent in the mobile node's home network

Abstract

A method for delivering at least one data packet is disclosed originating from a corresponding node in a corresponding network to a mobile node having a home network and being connected to a foreign network different from said home network, the mobile node having a long term IP address belonging to said home network and a care-of-address being the address of an foreign network access router of said foreign network, said networks being connected to an IP network comprising at least one data storage, by respectively a home network access router, a corresponding network access router, and said foreign network access router, the method comprising: a. intercepting said at least one data packet and detecting the destination IP address thereof; b. consulting said at least one data storage, whereby said care-of-address of said mobile node is retrieved by using the destination IP address of said at least one packet; c. forwarding said at least one data packet directly to said care-of-address, and indicating said long term IP address to said foreign network access router.

Description

technical field [0001] The present invention relates to network routing, and in particular to a system and method for managing the connection of a mobile node into a foreign network that is different from the mobile node's home network. Background technique [0002] The Mobile Internet Protocol (IP) enables mobile nodes to move freely from one connection point to another in different networks visited along its route. In particular, the Mobile IP protocol describes actions that enable a mobile node to maintain a connection during a handover from one access router to another. [0003] Mobile IP is described in specifications that can be found from the Internet Engineering Task Force (IETF) and others, for example in RFC (Request for Comments) 3344 and RFC 3776. Mobile IP enables a mobile node to be identified by its home address regardless of its current point of attachment to the Internet. It is also associated with a care-of-address that provides information about the mobi...
