Method for measuring service quality, network appliance and network system

Abstract

The invention relates to a method for measuring service quality, and network equipment and a network system thereof, wherein, the method comprises the steps that: received sender reporting RTCP SR messages in a real-time control protocol is transmitted to a second measuring point by a first measuring point; receiver reporting extra RTCP RR messages in an extra real-time control protocol transmitted by the second measuring point is received; and the QoS parameters between the local site and the second measuring point are calculated by the first measuring point according to the extra RTCP RR messages. The network equipment comprises a message generating unit and a second message transmitting unit; the network system comprises the first network equipment comprising a first message transmitting unit, a message receiving unit and a network segment service quality calculating unit; and the second network equipment comprises a message generating unit and the second message transmitting unit. The invention can realize the service quality measurement based on the network segments under the situation that the network burden is not increased.

Description

technical field [0001] The invention relates to network technology, in particular to a method for measuring service quality, network equipment and a network system. Background technique [0002] With the increase of service requirements and the development of Internet Protocol (IP, Internet Protocol) network technology, more and more real-time services are transmitted on the IP network. The addition of real-time services such as voice, video, multimedia, and teleconferencing poses new challenges to IP networks. How to ensure the quality of real-time services is currently a hot issue. The real-time protocol (RTP, Real Time Protocol) is an end-to-end transmission protocol used to transmit real-time service data. It provides information such as serial numbers and time stamps to provide the basis for the reassembly of the message at the destination of the message. However, RTP itself does not provide quality of service (QoS, Quality of Service) guarantees and real-time transmis...

AI Technical Summary

Problems solved by technology

[0021] It can be seen from the implementation process that in passive measurement, although no new RTCP packets are introduced, in passive measurement, the measurement point can only calculate the QoS parameters between the two ends and the local, and cannot calculate the QoS parameters between the adjacent measurement point and the local. Between the QoS parameters, therefore, passive measurement can not be based on network segment measurement

[0022] The inventor finds after careful analysis and careful study of the above-mentioned implementation process that the prior art also has the following defects: it is impossible to measure QoS based on network segments without increasing the network burden
