Problems solved by technology

[0009] Current router latency testing methods have certain limitations:
[0010] A. When using professional test instruments for testing, since the test instrument equipment is very expensive, the use of large quantities will seriously increase the test cost
[0011] B. When using PC and software for testing, the test results are limited by the performance of the PC and the time-consuming software processing. The obtained forwarding delay test result T=Tr-Tt+PC time-consuming, the error of the test results mainly comes from the time-consuming PC, if The performance of the PC is poor, and the test results will seriously deviate from the true value

Embodiment Construction

[0037] Embodiments of the present invention provide a forwarding delay testing method and system, which are used to improve the accuracy of testing forwarding delay with common testing equipment. The present invention will be specifically described below in conjunction with the accompanying drawings.

[0038] Figure 4 A schematic diagram of Embodiment 1 of a forwarding delay testing method of the present invention is given, and the method includes the following steps:

[0039] Step S1, configuring on the device under test to bind the first IP address to the MAC address of the third port of the device under test;

[0040] The first IP address and the IP address of the second port of the device under test belong to the same subnet;

[0041] For example, the next-hop IP address received by the device under test can be bound to the MAC address of the Ethernet port 3 of the device under test, and the first IP address is the same as the IP address of the Ethernet port 2 of the de...

Abstract

The invention provides a method and a system for testing forward delay, which are used for improving the accuracy of the forward delay test of common testing equipment. Through the configuration of a binding relation between a next hop IP address received by tested equipment and the port of the tested equipment on the tested equipment, the method enables a sent test message to perform circular test in the tested equipment. Therefore, the obtained result of the forward delay test has reduced errors caused by self time consumption in the forward delay test of a common testing instrument, so the high test cost caused by the use of a professional testing instrument is saved.

Description

technical field [0001] The invention relates to a forwarding delay testing method and system, belonging to the technical field of data communication. Background technique [0002] Router forwarding delay refers to the time consumed by a router for a series of operations such as receiving packets, searching the routing table, and forwarding packets, such as figure 1 As shown, suppose the time when the router receives the message is Tt, and the time when the router sends out the message after a series of operations is Tr, then the forwarding delay T is Tr-Tt. The router's chip speed, system bus, software algorithm, etc. will all affect the forwarding delay of the router. [0003] In a current Internet Protocol (IP) network, a router is the most important forwarding device in the network, and its various performance indicators will directly affect the performance of the entire network. [0004] In current network applications, various real-time communication services such as ...
