<p>Disclosed herein is a route optimization that allows packets flowing between a mobile node (MN) and a correspondent node (CN) to bypass local mobility anchors (LMAs), thereby improving flow efficiency and/or reducing network traffic. Specifically, the MN's mobile access gateway (MAG) and the CN's MAG may participate in a proxy binding update (PBU)/proxy binding acknowledgement (PBA) exchange with each other to establish the MN's and CN's state in the opposing MAG. After doing so, the two MAGs may send MN-CN packets directly to each other, e.g. without sending such packets to the LMAs. In one embodiment, the route optimization is applied to a situation where the MN's MAG and the CN's MAG are associated with the same LMA. In another embodiment, the route optimization is applied to a situation where the MN's MAG and the CN's MAG are associated with different LMAs.</p> |
