Traditional replication protocols don't take those issues into consideration such as adaptation to legacy system as well as affection to the system performance after introducing replication. Based on discussion about these protocols

a new replication protocol is addressed in this paper. Its design adopts logical token ring architecture with dynamically increasing/decreasing replicas. This paper discusses the system model and the request processing procedure of the protocol. With precondition to meet availability requirement

it not only enables adaptability to various distributed systems but also guarantees high performance of these systems. The comparison between this protocol and other typical replication protocols shows that it is feasible.
