Abstract

The present invention discloses a method and device to measure service quality parameters and a method and device to judge service quality. This method includes receiving BFD (bidirectional forwarding detection) packet and recording receiving time. The BFD packet carries sending sequence number and sending time; the sending sequence number and sending time are obtained from the BFD packet; service quality parameters are obtained based on the receiving time, sending sequence number and sending time. The embodiment of the present invention may save cost, raise efficiency and further locate degradation.

Description

technical field [0001] The invention relates to network communication technology, in particular to a service quality parameter measurement method and equipment, and a service quality judging method and equipment. Background technique [0002] In network communication, the QoS of the network can be judged by measuring the Quality of Service (QoS for short) parameters according to the measured QoS parameters, so as to take corresponding measures to ensure the QoS of the network. Among them, the QoS parameters mainly include delay, jitter, packet loss rate, etc. [0003] Existing methods for measuring QoS parameters are as follows: [0004] Prior Art 1: Measurement is performed by a dedicated QoS measurement device. figure 1 It is a schematic structural diagram of the first embodiment of the QoS parameter measurement method in the prior art. see figure 1 , the network includes a first router 11 , a second router 12 , a third router 13 and a fourth router 14 . When needing ...
