Method and system for confirming faults of IP bearer network

Abstract

The invention provides a method and system for confirming faults of an IP bearer network. Services between first equipment and second equipment are borne through the IP bearer network, the first equipment is connected into the IP bearer network through third equipment in the IP bearer network, and the second equipment is connected into the IP bearer network through fourth equipment in the IP bearer network. The method comprises the steps that the first equipment detects the quality of the services between the first equipment and the second equipment to confirm whether abnormal situations occur to the quality of the services between the first equipment and the second equipment. If the quality of the services between the first equipment and the second equipment is abnormal, the first equipment sends request messages to the third equipment, and receives the response messages sent by the third equipment, wherein the response messages carry the 5-tuple flow of the services and the quality parameter values of the services in IP bearer network. The first equipment confirms whether faults occur to the IP bearer network or not according to the quality parameter values of the services carried in the response messages.

Description

technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular to a method and system for determining failures of an IP bearer network. Background technique [0002] Services of a service network, such as next generation network (next generation network, NGN for short), wireless network and other service networks, may be carried by an Internet Protocol (Internet Protocol, IP for short) network. With the development of communication technology, the IP bearer network can carry more and more services, including wireless services, NGN services, IP television (Internet Protocol television, IPTV for short) services, and Internet access (Internet) services. Some services have higher requirements on the service level agreement (SLA) index of the IP bearer network. For example, SLA indicators include bandwidth, packet loss rate, delay, and delay variation. If the IP bearer network fails, it will affect the service quality of...
