Comparative Analysis of Dyanamic Routing Protocol using Packet Tracer 6.0.2 with Dyanamic BW

In a computer network, the transmission of data from source to destination is based on the routing protocol which selects the best routes between any two nodes. Different types of routing protocols are applied to specific network environment. Three typical types of routing protocol are chosen as the simulation samples RIP, OSPF and EIGRP. RIP (Routing Information Protocol) is one of the oldest routing protocols still in service. Hop count is the metric that RIP uses and the hop limit, limits the network size that RIP can support. OSPF (Open Shortest Path First) is the most widely used IGP (Interior Gateway Protocol) large enterprise networks. OSPF is based on the Shortest Path First (SPF) algorithm which is used to calculate the shortest path to each node. EIGRP Enhanced Interior Gateway Routing Protocol) is Cisco's proprietary routing protocol based on Diffusing Update Algorithm. EIGRP has the fastest router convergence among the three protocols. In this research paper we are going to study the effect of BW, Delay, communication mode and configuration scenario and also analyze the performance of IGP based RIP, OSPF and EIGRP routing protocol using CISCO proprietary simulator tool CISCO packet tracer-6.0.2 with dynamic BW.
