Abstract:
A way to deliver traffic to a mobile node that is undergoing a hand off between two Access Routers (AR) is described. The method of the present invention operates to perform some or all of the following: decrease, e.g., minimize, delays between the time the old link breaks and the first packet is sent from the new link; reduce and/or eliminate packet bursts from old to new AR when an old (existing) link breaks; ensure that packets are neither lost nor duplicated during hand off; maintain QoS control of delivery order to the MN; make good or best use of multiple links during make-before-break hand-off; and support both uplink and downlink traffic.
