Method, system and equipment for monitoring soft exchange load-bearing network quality

Abstract

The invention discloses a method for monitoring the quality of a soft-switch bearer network, a system and equipment thereof. A core probe for quality monitoring is deployed at one side of a service router (SR) in the soft-switch bearer network, while edge probes are deployed at the side of soft-switch core equipment. The method comprises the following steps: the core probe transmits a test data flow to each edge probe, each test data flow simulates the characteristic of soft-switch speech data flow; after the edge probes receive test data packets, the edge probes respectively return the test data packets to the core probe; after the core probe receives the test data packet, the core probe calculates test index of the data packets by contrasting transmitted data packets and received corresponding data packets, thereby obtaining network quality of a bearer network path reflected by each test data flow. On the premise that client perception degree of soft-switch service is fulfilled, the method achieves the aim of defining fault of an IP bearer network or the soft-switch service network as soon as possible, thereby shortening time for maintaining fault of the soft-switch service.

Description

technical field [0001] The invention relates to Internet Protocol (IP) network quality monitoring related technologies, in particular to a quality monitoring method, system and equipment of a softswitch service bearer network based on an external quality probe. Background technique [0002] With the application of IP services and integration of bearer services, the IP network has become a comprehensive bearer platform for the integration of various services. As the softswitch service is gradually carried on the IP network, due to the "best effort" feature of the IP network, the softswitch service will introduce packet loss, delay and jitter at the bearer level during the transmission process, resulting in end-to-end softswitch A decline in service quality. Therefore, it is necessary to meet the normal operation requirements of the softswitch service for the IP bearer network, and perceive the status of the bearer network from the service level to ensure the smooth developme...

Problems solved by technology

[0008] The measurement method of Cisco SAA needs to be supported by the equipment of each manufacturer to realize the measurement of network performance between different manufacturers' equipment on the IP network; enabling SAA also needs to occupy the system resources of the network equipment, which in turn affects the end-to-end bearer quality of the network; finally, It is not closely related to softswitch services, and cannot meet the needs of end-to-end quality monitoring and real-time monitoring of softswitch services

[0009] The built-in test and analysis module in the softswitch media gateway requires compatibility between the media gateways, that is, real-time monitoring of quality cannot be achieved between different softswitches; moreover, this monitoring method depends on the softswitch itself and cannot To monitor the quality of the bearer network transparently; in addition, this method is not conducive to defining the fault interface between the softswitch service platform and the bearer network, and is not conducive to network operation and maintenance
