ABSTRACT:
The disclosure provides a method, system and apparatus for backuping HA/MAP in mobile IPv6 network. In the disclosure, at least two HAs/MAPs form a redundant backup group. The at least two HAs/MAPs elect an active HA/MAP and a standby HA/MAP via the VRRP. When the active HA/MAP interacts the signaling message with a mobile node, the HA/MAP in backup status obtains the signaling message interacted by both of them in real time. When the active HA/MAP is invalid, the standby HA/MAP may take over the work in time so that the stability of the active node device of the network is ensured. During the exchange of the active HA/MAP and the standby HA/MAP, the solution ensures a smooth transition of the service.
