Distributed semi-physical network simulation system and controlling method of semi-physical port thereof

The invention discloses a distributed semi-physical network simulation system and a controlling method of semi-physical port thereof, comprising a network physical system and a network simulation system, wherein the network physical system comprises a plurality of network nodes and communication connecting equipment thereof based on military communication network; the network simulation system comprises a plurality of simulative PC machines operated with network simulative software, each simulative PC machine in the network simulative system has a semi-physical port; under the condition that the semi-physical port finishes the functions of information analysis, transmission and time management between the network simulation systems and between the network simulation system and the networkphysical system without changing any arrangement of simulative and physical system, the different simulative applications such as simulation and physical are connected with each other, each simulativePC machine has the semi-physical port, and the expandability of the system is strong.
