Communication is nothing but transfer of information from source point to destination point over a medium and coming to Communication Routing it is a process in which to find how shortest and fastest communication is achieved between the two ends for the Optimization of the Network. In this paper I would like to discuss about how optimization is achieved in communication network through the application of information like accuracy, throughput, latency and mobility support and different protocols followed by networks for the optimized route. And I will also explain about advantages of network coding in improving the throughput over routing. Explained how different network algorithms are used for solving optimization problems in communication routing for example like genetic algorithm used in routing optimization of optical fiber communication networks. And discussed about Optimizing the layered communication Protocols.
