Abstract
In a router or packet processing node supporting Mobile IP, a method for causing packets to be retransmitted from a sender to a mobile node is disclosed. A plurality of packets having associated update information are received. The packets are intended for the mobile node. The update information associated with at least one of the received packets is stored. When the mobile node is disconnected from the sender and reconnects to the sender, without waiting for a timeout the sender is directed to retransmit a last portion of packets to the mobile node based on the stored update information. Apparatus and computer readable medium embodiments are also disclosed.
