High service reliability for cluster server systems

In a cluster server system, service-types replication has been used to improve its reliability. However, different replication techniques have different reliability levels. In this paper, a new technique, called neighbor replica distribution technique (NRDT) using request distributed agent (RDA) is proposed to manage service-types replication in a cluster server under a local area network system. This technique provides high reliability by imposing a neighbor logical structure on service-types copies: service-type from one node will be replicated to its neighboring nodes. Our performance analysis shows that our technique is better than the previous technique since it produces a higher reliability.
