In this paper, we discuss an approach taken to enhance the performance of e-learning system that would be deployed in an unstable network and identify impact factors of such environment. We adopt a database replication technique which plays significance role in this rapidly growing use of ICT to enhance the quality as well as availability, sustainability and reliability of an unstable network by increasing the number of redundant cluster. Cluster is a group of nodes which consists the number of schools. Our approached system is based on the multi-aster highly available replication mechanism for distributed e-learning system.
