With network simulation tools to simulate C2 (Command and control) network services, the simulated network will reflect the relationship between the internal units and dynamic behaviors of the real C2 network. However, the service operating mode exactly matches the organization structure of the C2 network, the service operating mode can't be extended to other C2 networks through the hard-code way. In this regard, this paper presents the M2E2M (Model to Event to Message) method. By drawing the ideas of colored, timed, object Petri nets, we propose the Petri nets based modeling method of C2 network services. By using CPN Tools to simulate the model, we generate communication events set and achieve the conversion from model to event. In the VRNET Developer simulation platform, we complete the simulation of the events set and achieve the conversion from event to message through the development of the CmdEngine and CmdApp module. Finally we complete the simulation of an early warning service of a C2 network. The simulation results match the network organization structure and the simulation method is proved to be effective.
