Abstract:
1. A method for backing up a home agent or mobile anchor point (HA/MAP) in a mobile Ipv6 network, at least two HAs/MAPs forming a redundant backup group, comprising: electing, from at least two HAs/MAPs, an active HA/MAP and a standby HA/MAP; obtaining in real time, by the standby HA/MAP, a signaling message sent by a mobile node (MN) to the active HA/MAP and a signaling message sent by the active HA/MAP to the MN when the active HA/MAP performs a signaling message interaction with the MN; or sending status information in real time to the standby HA/MAP, by the active HA/MAP, via a synchronization message after the active HA/MAP performs the signaling message interaction with the MN; and electing, from the standby HA/MAP, a new active HA/MAP when the active HA/MAP is invalid; wherein after the standby HA/MAP obtains in real time the signaling message sent by the MN to the active HA/MAP and the signaling message sent by the active HA/MAP to the MN, the method further comprises: processing the signaling message sent by the MN to the active HA/MAP and the signaling message sent by the active HA/MAP to the MN obtained in real time, wherein the processing further comprises:
