| 摘 要： | 针对机群文件系统的个子操作出现错误会影响数据的可用性,提出了一种高可靠的消息传输机制HR-NET.将机群文件系统的网络故障分为3类:发送错误;接收错误;请求应答错误.对于前2种错误,提出了基于冗余传输路径的网络容错机制,对消息收发故障进行恢复,同时引入消息优先级调度策略,动态地调整消息的处理次序,避免请求应答类型的错误.通过分离并单独处理网络故障,HR-NET为机群文件系统提供了高可靠的通信机制,简化了上层文件语义操作的实现.测试结果表明HR-NET高可靠性机制所带来的性能损失低于9%.

| Abstract: | File operation in a cluster file system contains several sub-operations;each has one or more network transmissions.If passing messages fails,the file system will be unavailable.A high-reliable message-passing mechanism,which is called HR-NET was presented.The faults of network was separated into three different sub-factors: send error,receive error and echo error.HR-NET offers different solutions for them: fault-tolerant mechanism is used to resume send/receive error by using redundant transmission paths an... |
