Study on the Network Service Status's Detection and Recovery Strategy Based on Cloud Model

摘要

In this paper, taking the survivability of trusted network as the background, the key issues of network survivability are researched. Taking into account the uncertainty, randomness of network services, by introducing cloud model, the status of network service is described in this paper. Based on cloud model, this paper proposes the strategy of status detection for network service, the evaluation of network survivability and recovery strategy, and the associated theory analysis and confirmation are given. At the same time, this model proposed in this paper also enlightens a new way for study on the survivability of current complex network system.
