Embodiment 1

[0075] In order to solve the problems encountered when the standard TWAMP protocol is deployed in complex networking, the embodiment of the present invention proposes a solution for implementing link testing based on the lightweight TWAMP testing protocol. Among them, the above-mentioned link test method can be applied to but not limited to such as Figure 5 The shown architecture, the specific scheme is as follows: the embodiment of the present invention removes the control protocol in the standard TWAMP protocol in the link test process, and only keeps the test protocol, so that the standard TWAMP protocol is lightweight, thereby releasing TWAMP's restriction on the TCP / IP protocol. rely. When deploying the TWAMP protocol during the link test, there is no longer any restriction on IP planning or limited IP address resources. While making the deployment of the test protocol more flexible and fast, it also expands the scope of application scenarios for link testing, thereby im...

example 7

[0198] As an optional example 7): L2VPN end-to-end measurement, such as Figure 14 As shown, this embodiment is mainly used for end-to-end link measurement from an L2 access side to another L2 access side in an L2VPN networking. The TWAMP measurement is initiated from the L2 access device, and real-time statistics are collected from the access device on one side of the L2 to the access device on the other side of the L2.

example 8

[0199] As an optional example 8): L3VPN end-to-end measurement, such as Figure 15As shown, this embodiment is mainly used for end-to-end link measurement from an L3 access side to another L3 access side in an L3VPN networking. The TWAMP measurement is initiated from the L3 access device, and real-time statistics are collected from the access device on one side of the L3 to the access device on the other side of the L3.

[0200] As an optional example 9): In L2 to L3 end-to-end stacking measurement, such as Figure 16 As shown, this embodiment is used in L2+L3 complex networking, and the end-to-end link performance measurement between the L2 access device and the L3 core landing device is superimposed on the end-to-end link performance measurement of the L2 network and the L3 network segment. This measurement method is a superposition of Example 1 to Example 6, and can monitor the performance of each segment of the network in real time. It mainly includes the following steps...

Abstract

The invention provides a link test method, apparatus and system. The method comprises the following steps: obtaining a test message via a user network interface analog input message, wherein the test message is used for testing a current link by using a test protocol in a two-way active measurement test protocol TWAMP; sending the test message to a reflector; identifying a response message sent by the reflector in response to the test message, wherein the response message is matched with a pre-configured flow matching rule of the reflector; and obtaining a test result of the current link according to the response message. By adoption of the link test method, apparatus and system, the problem of relatively low test efficiency of testing the network link caused by the relatively large deployment difficulty of the standard TWAMP protocol is solved, and thus the effect of improving the efficiency of testing the TWAMP link is achieved.

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,...
