Abstract:
In a computer network, the transmission of data 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 would testing.
More detailed description of these three routing protocols would be
included later. Would aim to analyze the performance of the three
protocols such as their router convergence, convergence duration and sent
traffic. In our project, would going to use OPNET to simulate RIP, OSPF
and EIGRP in order to compare their attributes and performance.
According to the convergence would find out which protocols are suitable
for different sizes and types of network
