摘要

Objects are replicated in order to increase reliability and availability of an object-based system. If a method t is invoked on multiple replicas and each instance of t on the replicas invokes another method u on an object y, the method u is performed multiple times on the object of y although u should be performed just once. Then, the object gets inconsistent. This is redundant invocation. In addition, if each instance of the method t issues a request u to its quorum, more number of the replicas are manipulated than the quorum number of the method u. This is quorum expansion. We discuss a protocol to invoke methods on multiple replicas in a nested manner where the redundant invocation and quorum expansion are resolved. We evaluate the protocol compared with the primary-secondary replication.
