Study on the network system survivable status´s assessment and forecast model

In this paper, taking the survivability of trusted network as the background, the key issues of network survivability are analyzed. Taking account of the uncertainty, randomness of network system, by introducing cloud model and deterministic finite automation, the status of network system is described and detected in this paper. Based on cloud model, this paper proposes the network system status´s assessment and forecast model. Moreover, the analysis and confirmation of associated theory are given. Finally, the feasibility and rationality of this model is further confirmed by the aid of simulation experiments. At the same time, this model, which is proposed in this paper, also enlightens a new way for study on the survivability of current complex network system.
