Link bandwidth test method and router

Abstract

The invention discloses a link bandwidth test method. The method comprises the following steps that: when the link bandwidth between a source router and a target router needs to be tested, the source router transmits a link detecting message to the target router and obtains link information between the source router and the target router, wherein the link information comprises a corresponding interface IP address of all routers through which the link detecting message passes; respectively transmitting a bandwidth test message to all the routers and target routers according to the link information; and after receiving the bandwidth responding to all the routers and the target router, calculating the bandwidth of the whole link. The invention also provides a router based on the same conception. The invention overcomes the defects of higher arrangement cost and more network resource occupation of the traditional link bandwidth test.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a link bandwidth testing method and a router. Background technique [0002] With the development of various data services in the network, more and more attention is paid to the end-to-end service quality, such as VOIP, IPTV, VOD and other services are very sensitive to end-to-end available bandwidth, delay, jitter and packet loss, these performance Parameters seriously affect the development and operation and maintenance of this type of business. For these services, the guarantee of sufficient end-to-end available bandwidth is a prerequisite for conducting services. For operators, end-to-end bandwidth measurement is of great significance for analyzing network bottlenecks, optimizing the network, and maintaining services. [0003] see figure 1 , figure 1 It is a schematic diagram of a typical application for the development of data services. figure 1 Router 101 and rout...

Problems solved by technology

This method is to conduct traffic estimation by continuously sending test data, which occupies a large amount of network resources and will affect the normal business performance of the network.

[0007] The third method is TOPP (Trains of Packet Pairs). This method is similar to the SLoPS method and needs to send a large number of detection packets, which occupies a large amount of the network. In the actual network test, it needs to pay a large price and has certain dangers.

[0008] It can be seen from the above that the current method of testing link bandwidth has the disadvantages of high deployment cost and large network resources
