摘要:This paper reported another recovery model to enhance system survivability. The model focuses on how to preserve the system and resume its critical service while incident occurs by reconfiguring the damaged critical service resources based on available resources without affecting the stability and functioning of the system. There are three critical requisite conditions in this recovery model: the number of pre-empted non-critical service resources, the response time of resource allocation, and the cost of reconfiguration, which are used in some scenarios to find and re-allocate the available resource for the reconfiguration. To validate the viability of the approach, one instance case is provided. The adoption of fault-tolerance and survivability using redundancy re-allocation in this recovery model is discussed from a new perspective
