1. A method for route optimization that does not require a return routability procedure, the method comprising the steps of:
(a) receiving, at a home agent, a first update message transmitted from a mobile node, the first update message comprising a care-of-address (CoA) associated with the mobile node, wherein, in response to receiving the first update message, the home agent binds the CoA associated with the mobile node with a home address assigned to the mobile node; and (b) after receiving the first update message, transmitting a second update message from the home agent to a correspondent node, the second update message comprising the CoA associated with the mobile node and the home address assigned to the mobile node; wherein step (b) is not performed until the home agent determines there is a trusted relationship between the mobile node and the correspondent node, and wherein the trusted relationship exists if the home agent determines there is an end-to-end cryptographic relationship between the mobile node and the correspondent node, and wherein the correspondent node is a node with which the mobile node is communicating; wherein the correspondent node is a mobile node and the correspondent node has the same home agent as the mobile node, and the method further comprises: (c) receiving, at the home agent, a third update message transmitted from the correspondent node, the third update message comprising a CoA associated with the correspondent node, wherein, in response to receiving the third update message, the home agent binds the CoA associated with the correspondent node with a home address assigned to the correspondent node, wherein step (b) is not performed until after the home agent receives the third update message. |
