METHOD AND SYSTEM FOR MANAGING PACKET FORWARDING PATH, AND NETWORK ELEMENT

摘要

A method for managing a packet forwarding path comprises: a first mobile access gateway (MAG) sending an address query request to a mapping server, the address query request carrying node information of a correspondent node (CN); the mapping server receiving the address query request, querying a binding caching table, obtaining MAG information of the CN corresponding to the node information of the CN, the MAG information of the CN pointing to a second MAG; the mapping server directly sending an address query response message to the first MAG, or after forwarding the address query request to the second MAG, the second MAG sending the address query response message to the first MAG, the query response message carrying the MAG information of the CN; and the first MAG receiving the address query response message.
