Problems solved by technology

The loopback method only needs one tester, but requires loopback to be implemented on the internal or external link of the system under test, and its test capability is too simple, so it is not practical enough; the pass-th

Example Embodiment

[0058] Embodiment of the invention

[0059] The present invention will be described below with reference to the drawings.

[0060] Such as image 3 As shown, the bottom-layer convergence test method uses one tester to simulate multiple virtual testers, and all virtual testers are connected to the system under test through the same link, avoiding coordination problems between multiple physical testers. The concentrator can be a hub, which functions to converge the underlying interface of the relay system under test, so that the tester can communicate with multiple lower interfaces of the tested implementation, and stimulate / respond to the tested implementation through multiple underlying interfaces Test, can test various relay functions realized by the relay system under test. The bottom-layer convergence test method can also be used to test the end system. At this time, the aggregator works in transparent mode, which is equivalent to that the lower interface of the end system under...

Abstract

A convergent test method for communication protocol base includes accumulating tested relay system base interfaces with an accumulator, simulating realization of many virtual testers with one tester;all virtual testers are connected with the tested system by a same link route; the tester communicates with many low interfaces of tested realization via the accumulator and performs excitation/response test to the tested realization via multiple base interfaces. The invention realizes cross test to the relay system on a tester, without any special requirement, to realize consistency test with only one tester.

Description

technical field [0001] The invention relates to a computer and telecommunication communication protocol consistency test, in particular to a bottom layer aggregation test method and system 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, and entities can be [0005...
