Network analog simulation system for large-scale integrated data network based on NS-3

The invention discloses a network analog simulation system for a large-scale integrated data network based on NS-3. The network analog simulation system is characterized by comprising three subsystems: a visualization system (1), an analog simulation system (2) and a network operation analysis system (3). A framework used by the network analog simulation system compensates and perfects the defect of an existing NS-3 function module; 22 function modules systematically built based on an NS-3 platform and a parallel module provide an omnibearing function support for the simulation of the integrated data network. According to the network analog simulation system, technologies of route analysis, flow analysis, data network element analysis and the like can be integrated based on overall operating status data of the integrated data network; through the realization of the framework, a simulation platform for rapid fault location and diagnosis and network performance analysis can be provided at high efficiency and high precision.
