Due to last two decades emergence of internet has increased rapidly and becomes the basic need in today life. Due to this emergence the factor of reliability, performance and security are common issues that we must consider. We are presenting here the reliability and performance of the internet by clustering the networking devices. The conception behind this is to make a bigger system by using a multiple smaller units. The main matter in this concept is to make a connection reliable and to increase the system functioning without using any extra connection. For this multiple networking components operates together for the same reason and this create a distributed system in networking atmosphere. The goal of this distributed system is to permit both load balancing and be unsuccessful between the nodes. In load balancing the overall throughput is increased by distributing network load among the member of the cluster. If any nodes crashed or failed then it is the responsibility of active node to find it and bear the network load from the crashed node without disturbing the data flow. A Model which motivates the creation of PRISM, a suit of distributed protocols and services designed to help networking devise which become more fault tolerant and preferment is described in chapter three which has emerged as a problem in sequel of survey conducted with employees of the computer hardware and software industry. Structural equational modeling is used to determine the required values and to finally prove the model.
