Problems solved by technology

[0017] The disadvantages of using multiple bench testers to test the implementation under test are: Multiple down testers are physically separated, so observations of the same test event differ in time
Multiple sub-testers exist in different systems, and there must be a good synchronization and control coordination process between them, which complicates the testing process

Embodiment Construction

[0033] In actual protocol testing, the implementation under test judges which tester the test packet comes from based on the address. For example, when testing the protocol of the link layer, the implementation of the link layer protocol under test judges which tester the test packet is sent from according to the address of the link layer; when testing the protocol of the network layer, it is The implementation of the network layer protocol under test judges which tester the test packet is sent from based on the address of the network layer; Which tester it was sent from. In the actual protocol test, the present invention proposes to use one physical tester and different network addresses of peer-to-peer layers to realize the test structure of multiple lower testers.

[0034] Figure 4 It is a virtual test structure implemented by a single down-tester to implement a conformance test on the n-layer protocol under test. Among them, VT1, VT2, and VT3 are multiple virtual teste...

Abstract

A virtual test method in a consistency test of a communication protocol includes that the method is realized by judging according to the address the source of test packets; different tested protocolsare used to realize network address of the peer to realize multi-virtual tester, a logic testing structure is set up with multi-virtual download testers and use only one download tester to realize the software (or system) test to tested protocol on the bases of guaranteeing the effectiveness and accuracy, avoiding complicated coordination among testers.

Description

technical field [0001] The invention relates to a computer and telecommunication communication protocol consistency test, in particular to a virtual test system and method in the communication protocol consistency test. Background technique [0002] Protocol conformance test is a kind of "functional test". It tests 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. It only determines the function of the protocol implementation by observing the external behavior of the protocol implementation according to the description of the protocol, and does not involve the internal structure of the protocol implementation. [0003] In order to illustrate the protocol conformance testing method, the following basic concepts are given. [0004] 1. Entity: OSI refers to the active elements in each layer as entities, which can be either hardware entities (such a...
