Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] The virtual trunk test method of the present invention not only has to overcome the defect that the loopback test method can only test the trunk behavior in the same subnet involving only one port on the trunk system, but also overcomes the need for multiple testers, testers and The defect of complex environment. Considering the versatility of the through-test method, the present invention improves on the basis of the through-test method.

[0034] In an IP network, a router is the most typical relay system. The router is located in the middle of the IP data packet transmission path and is responsible for relaying the received data packet to the next hop node specified by the routing table. Adjacent routers exchange information through routing protocols to form routing tables. The following takes the router as an example to describe th...

Abstract

The invention provides a virtual trunk measuring device for network protocol, comprising a measuring device which comprises a centre control module and at least one virtual measuring module. The virtual measuring module is arranged for creating a packet content which will be sent to a measured trunk system, sending the packet to the measured trunk system, receiving and checking the packet from themeasured trunk system, wherein addresses of link layer of the packets which are created and processed by different virtual measuring modules are different. The centre control module is arranged for coordinating and managing the measurement of virtual measuring modules, wherein a port of the measuring device is connected to a port of the measured trunk system. The invention can simplify the measuring environment and avoid the coordinating synchronization among a plurality of measuring devices. The measuring result is more reliable and accurate.

Description

technical field [0001] The invention relates to a network protocol consistency test, in particular to a network protocol virtual relay test method. Background technique [0002] Protocol conformance testing refers to testing an implementation of a protocol based on the description of a protocol to determine whether the implementation of a protocol is consistent with the corresponding protocol standard. The protocol conformance test can verify the correctness of network equipment protocol implementation, and ensure that network equipment produced by different manufacturers in the network can operate correctly and interoperate smoothly, thus ensuring the normal operation of the network. [0003] According to the different systems under test, the protocol conformance test can be divided into the test of the peer system and the test of the relay system. The end system refers to the network equipment located at both ends of the network data packet transmission path, and the rela...
