Abstract: A method for realizing route forwarding in a network, including: establishing LSPs in a bearer network; setting an entrance label in the starting node of each LSP pointing to forwarding information of the LSP; a bearer control entity assigning a transfer path for the service flow and sending the information of all corresponding entrance labels of the transfer path to the ingress edge node of the transfer path; when the service flow needs to be forwarded, the ingress edge node puts the label stack into the data packet of the service flow to generate an MPLS exchange packet; and forwarding the MPLS exchange packet in the bearer network according to the label stack until the packet reaches the egress edge node of the transfer path. The present invention grants high compatibility to the network, minimizes the network investment, and reduces the difficulties in network implementation.

Abstract: A method for guaranteeing service reliability in an end-to-end Quality of Service framework, including: checking whether connection information held in all node equipment gone through by a session connection is consistent; if it is, finishing the consistency check; otherwise, releasing the inconsistent connection information from the node equipment. In this invention, consistency check is performed inside every node equipment, and between node equipment in the network, and thus, abnormal resources may be retrieved, so that network service ability will not be affected by abnormal situations. When the network is of large scope, consistency check can be done according to signaling flow sequence for establishing a session connection. When an inconsistent situation is detected, the node equipment gives a feedback to its upstream node equipment. Usually, there is a great quantity of sessions on a network, so it is better to carry out consistency check in batch for decreasing spending. With this method, degradation of service ability because of network abnormity can be avoided, and network reliability and availability can be improved, which is of great economic benefits.

Abstract: The present invention discloses a signalling exchange method for guaranteeing Internet Protocol (IP) Quality of Service (QoS), including: after a Call Agent (CA) receives a request from a source User Agent (UA) for transferring a user service stream, sending a QoS resource request from the CA to the bearer control layer; allocating resources for the user service stream on the bearer control layer, and carrying out flow mapping for an Edge Router (ER) according to the resource allocation result; after receiving a flow mapping command, the ER allocating a bearer path for the user service stream based on the allocated resources, and transferring an execution result to the CA via the bearer control layer. The invention provides a secure and reliable IP QoS signalling process for determining a bearer path of a user service stream, which is of convenience to allocate bearer paths for the network with an independent bearer control layer.
