Strategic Approach to the Selection of Appropriate Replication Technique to Model a Fault-Tolerant Internet Connectivity

摘要

The network is a highly dynamic environment where even subtle changes can now have a major, unforeseen impact on application performance and availability causing Internet failures. A system with faults/failures may continue to provide its services (i.e., not fail). Such a system is said to be fault tolerant. This is our focus in this research, to provide Internet services to clients without any interruption even at the presence of faults, through the deployment and redeployment of replicated proxy servers using Markov Reward Model. To achieve this, this study considered different replication techniques that can be used for Internet connectivity and finally suggested the best technique for use.
