Claim:
1. A method for monitoring a locator/identifier separation network comprising: receiving, by an access service node (ASN), a data packet from a mobile node (MN), wherein, the data packet comprises a source address and a destination address, the source address comprises an identity identifier of the MN and the destination address comprises an identity identifier of a correspond node (CN); querying a mapping table of identity identifiers and location identifiers according to the identity identifier of the MN and the identity identifier of the CN to find corresponding location identifiers; taking a location identifier of the ASN as the source address and taking a location identifier of a destination ASN accessed by the CN as the destination address to be encapsulated into a header of the data packet, and then routing the data packet to the destination ASN through a general forwarding plane; when a supervision center wants to monitor data packets of one MN which can be the MN or the CN and acts as a monitored MN, sending, by the supervision center, identity information of the monitored MN to an authentication center of the locator/identifier separation network, querying and obtaining an identity identifier of the monitored MN; querying, by the supervision center, the mapping table of identity identifiers and location identifiers according to the identity identifier of the monitored MN, and obtaining from the mapping table, by the supervision center, a location identifier, which corresponds to the identity identifier of the monitored MN, of a corresponding ASN accessed by the monitored MN; sending, by the supervision center, a command of monitoring the monitored MN to the corresponding ASN according to the location identifier of the corresponding ASN; and sending, by the ASN, a mirrored data packet corresponding to the data packet in which address information contains the identity identifier of the monitored MN to the supervision center.
