Embodiment Construction

[0043] For an IP network containing a single autonomous system, the present invention mainly considers two main types of routing convergence performance: OSPF convergence performance and iBGP convergence performance. For these two types of convergence performance, convergence time is used as its performance index. It should be noted that the method proposed by the present invention is generally used before the network is officially put into use, and the background traffic in the network is very small.

[0044] (1) OSPF network convergence performance test method:

[0045] The so-called OSPF convergence time refers to the time it takes for all routers to learn about the change and update their respective routing tables when the network topology changes in an autonomous system. According to the above definition, in order to test this index, the time required for each router in the autonomous system network to change from the network topology to update its routing table should be mea...

Abstract

The invention relates to a method for testing convergence property of autonomous system network route, belonging to the technical field of network test. The invention is characterized in that the method respectively tests the convergence property to an open shortest path first (OSPF) network and an internal border gateway protocol (iBGP) network. A testing scene is firstly constructed, two router nodes in the network are selected, and a flow generator and a flow acquirer are respectively equipped on these two router nodes; and in the iBGP router convergence property testing, the flow acquirer is used as a router simulator at the same time. With the introduction of network link, node failure event or BGP simulation route oscillation, at the same time, the planar transmission performance indices of network data are measured, and convergence time of route control plane can be estimated according to the message number transmitted and received from the flow generator and flow acquirer. The inventive method has low requirements to testing equipments and is easy to implement.

Description

Technical field [0001] The invention belongs to the field of Internet technology, and particularly relates to the field of network testing technology. Background technique [0002] Network testing technology plays an important role in every stage of network construction. Before network construction, according to the requirements of network design for network equipment, optional equipment can be selected and tested to select suitable equipment. After selecting and purchasing appropriate network equipment, and completing the network construction, the overall performance of the network needs to be tested and evaluated. After the network is put into operation, if the network needs to carry new services and applications, testing methods should generally be used to evaluate the performance of the network for new applications. Testing technology is also widely used in network operation and maintenance. [0003] The routing protocol is an important part of the network architecture. The I...
