<P>PROBLEM TO BE SOLVED: To provide a network simulation system in which a test corresponding to a communication protocol on an application level can be carried out. <P>SOLUTION: The network simulation system comprises: a virtual network 2 structured on a physical computer and in which a plurality of virtual computers A, B, ..., N are interconnected logically; an information sharing memory region 3 in which the information is shared among the plurality of virtual computers; and a memory copy function 4 for copying the internal state information of the plurality of virtual computers in the information sharing memory region 3 in real time. According to an application program a2, a packet transmission program b3 for test of the virtual computer B sends communication packets sequentially according to the procedure of a previously created internal state/communication packet correspondence table b4, with reference to the internal state information a1', and simulates the virtual network 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
