基于CORBA的容错对象复制算法

A FAULT-TOLERANT OBJECT REPLICATION ALGORITHM FOR CORBA

描述了一种基于 CORBA远程对象调用机制的容错对象复制算法 .它采用 prim ary- backup复制机制 ,客户方主动参与容错 ,能够重新调用请求并保证 at- m ost- once语义 ;实现了复制协议与可靠通信协议的分离 ;所采用的容错机制对用户完全透明 .而且通过在自主研制的分布计算平台 Star Bus上的实现 。

Described in this paper is a fault tolerant object replication algorithm based on CORBA. The algorithm uses primary backup replication, which enables clients re invoke requests and ensure its at most once semantics, and separates replication protocol and reliable communication protocol. Fault tolerance provided by the algorithm is fully user transparent. Finally the demonstration is given for this algorithm based on StarBus platform.
