Problems solved by technology

[0003] However, the existing network simulation is to directly select the existing network functional unit model from the preset unit library. The instantiated network function and running protocol are fixed, and users cannot customize it. New networks, new devices, and new protocols It often requires customized development and design, and cannot quickly and effectively simulate new networks, new devices, and new protocols, and it is difficult to meet users' needs for new functions and protocol support

Abstract

The invention discloses a network function unit simulation modeling method, and the method comprises the steps: carrying out the abstraction description of a network function unit according to a user-defined modeling statement which is used for describing a network function composed of different types of components from multiple dimensions; dividing the abstracted and described network function units according to module functions to generate a source file which at least comprises an input and output module, a message analysis module, a message processing module, a state machine module and a message recombination module; preprocessing the source file to generate a one-dimensional array list; analyzing the one-dimensional array list to generate an analysis result, judging whether the grammarof the analysis structure is correct or not, and if the analysis result is correct, generating a syntax tree and storing an input file composed of the analysis result; and performing instantiation operation on the network function unit according to the syntax tree and the input file. The invention further discloses a network function unit simulation modeling system, and therefore abstract and formalized modeling can be conducted on the network function unit.
