Abstract	As PC clusters increase in popularity and quantity, message-passing between nodes has been an important issue for high failure rate in the network. File access in a cluster file system often contains several sub-operations, each includes one or more network transmissions. Any network failures will cause the file system service unavailable. In this paper, we describe a highly reliable message-passing mechanism (HRNET), which tolerates both software and hardware network failures. HR-NET provides fine-grained, connection-level fail over across communication path redundancy. With it the file system can keep passing messages until it either recovers from network failures or it is failed over to a backup. Load balance for messages is also achieved to relieve network traffic. For transmission timeout, HR-NET proposes the message priority scheduling which dynamically manages messages in an appropriate order to tolerate request-response failures between clients and servers. As HR-NET is completely independent, there are neither any changes to standard protocol stacks nor modifications at upper file system. Performance results show that HR-NET takes full advantage of network bandwidth with average 6.17% throughput loss and provides a fast recovery. Experiments with cluster file system dispose that the overall performance degradation is below 8% due to failover of HR-NET while the reliability is highly enhanced.
