“…By this mechanism, each server will update its load state periodically to its server group while its load state is changed by equation ( I ) and (2). And, the most heavyloaded server will inform NFS client to change its target server to another candidate server, choose by the most heavy-loaded server.…”

The explosive growth of the Web contents has led to increasing attention on two major challenges: scalability and high availability of network file system. In this paper, we introduced the concept of intermediate file handle to improve the availability of NFS-based file system and proposed a new data consistency scheme to improve OUT design of reliable file system, which had been implemented as an example of the software replication approach. By using minor sequence in token getting, the total number of getting-token request gets reduced along data-requested size for each write operation. And, we also proposed a simple load-sharing mechanism for NFS client to switch to lightlyload server based on the number of NFS client's RPC requests for a period of time. Such an approach is easy to derive the load information, which each client generated. Finally, we analysed the proposed data consistency scheme. It shows truly that the scheme is able to reduce the overhead of write requests of our network tile system.

“…Commercial solutions include clustering [2,11], hardware support, such as usage of dual-ported disks [3], and others. Such solutions however are susceptible to "site-disaster", For example, the network link to the cluster may fail or simply be temporarily congested, rendering the whole cluster inaccessible and disrupting the service, while nodes in the cluster are functional.…”
