In the age of internet all people want a high speed data communication. For worldwide communication need a large network. The speed of any network is basically dependent on the data transfer rate and the delay. If the delay is small in any network the data transfer rate is increases. In this project we will try how to minimize the delay in the transmission path using different type of routing protocols. We consider a large network for my project purpose. The network consists by the routers, switches, and PCs. Configure the network using software named Packet tracer v5 and Boson v7. Before explore our project work we must need to know about IP subnet. Without subnet we can't configure any routers, hosts, or switches. Because can't set the source address and destination address.
