Link testing method and device and system

Abstract

The present disclosure provides a link testing method, apparatus and system. The method comprises: obtaining a testing packet by means of a user network interface analog input packet, the testing packet being used for testing a current link by using a testing protocol in a two-way active measurement protocol (TWAMP); sending the testing packet to a reflector; identifying a response packet sent by a reflector in response to the testing packet, the response packet matching a preset flow matching rule of the reflector; and obtaining the testing result of the current link according to the response packet. By means of the present disclosure, the problem of low testing efficiency caused by great difficulty of the deployment of a standard TWAMP when a network link is tested is resolved, thereby achieving the effect of improving the TWAMP link testing efficiency.

Description

technical field

[0001] The present invention relates to the communication field, in particular, to a link test method, device and system. Background technique

[0002] TWAMP protocol (Two-Way Active Measurement Protocol) is an IP performance measurement protocol, which is mainly used for performance measurement such as IP network link delay and packet loss rate. The TWAMP protocol consists of two protocols: TWAMP Control Protocol (TWAMP-Control) and TWAMP Test Protocol (TWAMP-Test). TWAMP-Control is mainly used to initialize, start and stop test sessions. TWAMP-Test is mainly used to exchange test packets between the test endpoints and measure IP performance at the same time.

[0003] TWAMP usually consists of four logical entities, a simple architecture such as figure 1 Shown:

[0004] 1) Control terminal (Control-Client): TWAMP test initiator, which sends a request to establish a control connection to the Server entity, negotiates the communication mode of the message,...
