Modeling and Analyzing Intrusion-tolerant and Performance Characteristics of Replicated Systems

摘要：

Replication is the key technique to providing high availability, fault tolerance, and desirable performance in a distributed intrusion-tolerant system ， but replicating all the services often leads to the descending of capability. To reduce the cost of resource, this paper presents a partial replication version of intrusion tolerance model. In the model, partial replication is adopted to reduce the cost of resource, instead of replicating all of the services. To overcome the problem of inconsistent serialization orders caused by partial replication, a sufficient condition to guarantee the overall correctness is also given-which requires the union of all local serialization graphs to be acyclic.
