Problems solved by technology
Therefore, the existing technology lacks a mechanism for the bearer control layer to obtain the LSP status of the bearer layer in a timely manner, so that the bearer layer cannot respond to LSP failures in a timely manner, affecting the connection rate of services such as voice and the stability of network operations. Failure to discover and deal with LSP failures in time will also cause problems such as long-term occupation of network resources that cannot be recovered

Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Take the bearer control layer network using the COPS+ protocol as an example, where the COPS+ protocol is an extension of the COPS protocol. Referring to the schematic diagram of the network structure of the bearer network resource manager shown in Figure 2, the user (UE) 201 sends a connection request to the CA 102 through the node protocol (Session Protocol), and the CA 102 sends the connection request to the corresponding bearer network through the COPS+ protocol The resource manager 101, the bearer network resource manager 101 analyzes the connection request, allocates corresponding resources for the requested connection, selects an appropriate route, and sends the policy routing information to the corresponding router in the domain through the COPS+ protocol.
[0029] In order to enable the bearer network resource manager ...

This invention discloses an automatic test and process method for labeling the exchange path states including the following steps: CN detects the abnormal changes of LSP state to deliver a connection state abnormal information to its belonged load network resource manager, then transfers resource release load network resource managers and / or lower reaches managers along LSP path till its destination and the source manager, the manager releases said LSP resources and cancels all session connections of said LSP, which realizes the understanding and synchronization to actual state of the load control layer to LSP state.
Description
technical field [0001] The invention relates to Internet network service management technology, in particular to an automatic detection and processing method of label switching path (LSP) state. Background technique [0002] With the continuous increase of Internet scale, various network services emerge one after another, and advanced multimedia systems including voice, image and other services emerge in endlessly. Since real-time services are sensitive to characteristics such as network transmission delay and delay jitter, real-time services will be greatly affected when there are high-burst FTP or HTTP services containing image files on the network; on the other hand, Multimedia services occupy a large amount of bandwidth, so it is difficult for the key services to be guaranteed by the existing network to be reliably transmitted. [0003] Therefore, various Quality of Service (QoS, Quality of Service) technologies emerge as the times require. In order to meet the require...
