Autonomic system network routing convergence performance testing method

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...

Problems solved by technology

The BMWG (Benchmarking Methodology) working group of the IETF has developed indicators and methods for the routing protocol convergence performance test of a single device (RFC 4061, draft-ietf-bmwg-igp-dataplane-conv-meth-13), but these standards are only for A single device does not provide a corresponding test method for the routing convergence performance in the actual AS network

Judging from the current research status at home and abroad, there is still a lack of research on the overall test scheme for network routing convergence performance.
