DESIGN AND SIMULATION OF A RELIABLE DISTRIBUTED SYSTEM BASED ON FAULT TREE ANALYSIS

ABSTRACT: Distributed Systems is the study of geographically separated processors, connected to one another with the help of intermediate devices such as routers and/or switches. Simulation provides an insight into the behavior of these distant apart systems. The internal details like designing, configuring and maintaining a reliable distributed system through protocols that include routing, switching, etc is well understood by this paper. The paper describes how the design of a distributed system be built on a Network Designer while using leased line, serial ports and Ethernet technologies. Further, these designs have been simulated on a Network Simulator with the use of routing protocols. For this scheme to be implemented successfully different equipment like routers, switches, Ethernet and serial connection, PCs, etc are used and techniques like IP addressing schemes and RIP are implemented. Further, the developed system is decomposed to form a Fault tree and its reliability is evaluated with the help of Fault tree Analysis
