Abstract:
1. A network based on identity identifier and location identifier separation architecture, the network comprising an access network and a backbone network, and the access network and the backbone network having no overlap in topology relationship, wherein: the access network is located at an edge of the backbone network, and is set to achieve accessing to the access network of an endpoint; the backbone network is set to achieve routing and forwarding of a data message between the endpoint and other endpoint which access to the backbone network via the access network; in the network, an access identifier (AID) is taken as an identity identifier of an endpoint user, and a routing identifier (RID) is used as a location identifier of the endpoint; the backbone network is divided into two planes during networking: a generalized forwarding plane and a mapping forwarding plane; the generalized forwarding plane is set to route and forward the data message which take the RIDs as destination addresses according to the RIDs in the data message; the mapping forwarding plane is set to store AID-RID mapping information of the endpoint, to process registration and inquiry of a location of the endpoint, and to route and forward the data message which take the AID as the destination address; the network further comprises an access service node (ASN), the ASN is included in the backbone network, the ASN is located in the boundary nodes of the generalized forwarding plane, the mapping forwarding plane and the access network, and has interfaces to the access network, the generalized forwarding plane, and the mapping forwarding plane; or the ASN is independent of the backbone network, and is located in the boundary node of the backbone network and the access network, and the ASN has interfaces to the access network and the backbone network; the ASN is set to provide access services for the endpoint, maintain connections between the endpoint and the network, allocate the RID to the endpoint, register the RID of the endpoint to and inquire the RID of the endpoint in the mapping forwarding plane, maintain the AID-RID mapping information, and achieve the routing and forwarding of the data message between the endpoint and the other endpoint; when there are more than one ASNs, there are a signaling interface and a second data forwarding interface between the ASNs, and the signaling interface between the ASNs is set to switch transmission of the management signaling during the switching, and deliver a RID update message when the location between the communication peer endpoint changes; the second data forwarding interface is set to forward data between the ASNs during the switching, wherein, the data message at the second data forwarding interface includes the tunneling encapsulation.
