METHOD AND DEVICE FOR MOBILE IP

摘要

A method of mobility management in a data packet network employs list-based multi-casting for distributing a careof address of a mobile node (5) in the form of a binding update. The binding update, which includes a list of recipient correspondent nodes (2,3,4) is forwarded sequentially to each correspondent node in the list by routers (6,7) which duplicate the binding update whenever an interface towards a subsequent hop diverges. The method is a particularly efficient in terms of signalling overhead in cases where between two and ten correspondent nodes are involved.
