The invention relates to a software architecture method and a software platform for a protocol consistency test. The software architecture method comprises the following steps: constructing basic typedefinition and connection management; constructing basic function and related protocol package, and locating the basic function and related protocol package on the upper layer of the basic type definition and connection management; constructing service function and consistency evaluation package, and locating the service function and consistency evaluation package on the upper layer of the basicfunction and related protocol package; and constructing a consistency test case, and locating the consistency test case on the upper layer of the service function and consistency evaluation package. According to the software architecture method provided by the invention, the level and module division is clear, the feasibility is high, the extension and maintenance are convenient, and the softwarerequirements of the protocol consistency test can be well satisfied.
