Method of operating tunnel point supporting routing scalability and mobility
First Claim
1. A method of operating a tunnel point which provides a tunnel between a router group including at least one router and a mobile node, the method comprising:
- providing a tunnel between the mobile node and the router group by authenticating the mobile node;
receiving a packet including an identifier (ID) of a target node from the mobile node;
converting the ID of the target node in the packet into a locator corresponding to the ID of the target node regardless of whether the mobile node is connected to a home agent or an external agent;
transmitting a packet including the converted locator to the router group; and
maintaining the ID of the mobile node by authenticating the mobile node through the router group when the mobile node is connected to another external terminal node,wherein a first tunnel point requests the ID of the mobile node and locator mapping information from a second tunnel point to which the home agent of the mobile node is connected, converts the ID of the mobile node into a locator of the mobile node based on the information delivered from the second tunnel point, and transmits a packet including the locator of the mobile node directly to a third tunnel point to which the external agent of the mobile node is connected.
