Problems solved by technology

[0005] To sum up, in the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: in the existing network path monitoring method, the monitoring process must depend on the source node or target node of the network path, and cannot The network path monitors and analyzes the nodes of the entire path, so that once data abnormalities occur, it is impossible to quickly and accurately determine which node along the network path is abnormal, which cannot meet the needs of current network quality monitoring

Embodiment Construction

[0023] Embodiments of the present invention provide a method, device and system for monitoring network paths. By using the signaling mechanism to inform the nodes along the network path to reserve forwarding paths and measurement policies, the nodes along the network path can monitor the NQA test data in the network path. That is to say, the NQA based on the signaling mechanism can monitor the test data on the nodes along the network path, so that each node along the network path can participate in the monitoring of the network path without depending on the source of the network path. Nodes or target nodes, so as to realize the purpose of monitoring the whole path nodes of the network path, make the monitoring granularity of NQA higher, and meet the requirements of the quality monitoring of the existing network.

[0024] At the same time, the monitoring result processing device can also perform corresponding analysis and processing on the network path according to the monitori...

Abstract

An embodiment of the invention provides a method and a device for monitoring network path, comprising: firstly, receiving a control signaling from an upper node; and then monitoring the network path based on the received control signaling. Each node on the way in the network path can take part into the monitor of network path by using the signaling mechanism, such as, the nodes on the way acquire, adjust and analyze the NQA test data by controlling the signaling, and the monitor result process device can also rapidly and correctly judge which node occurs abnormity on the way of the network path by the feedback monitor result of the nodes on the way, realizes an all path nodes monitor and analysis on the network path, makes the monitor granularity of the network quality higher, and satisfies the require of network quality monitor.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for monitoring network paths. Background technique [0002] At present, Network Quality Analysis (NQA, Network Quality Analysis) technology can be used to measure the performance of various protocols running on the network, so that service operators can collect various network operation indicators in real time, such as forwarding packet loss, delay, Jitter, etc.; then the network performance quality can be analyzed according to the collected index information. In practical applications, NQA technology can be used to detect data packets of protocols such as Hypertext Transfer Protocol (HTTP, HyperText Transfer Protocol), Transmission Control Protocol (TCP, Transmission Control Protocol) and User Datagram Protocol (UDP, User Datagram Protocol) The forwarding performance of the network, and the corresponding analysis of the transmission quality and performan...
