Abstract:
Routing protocol is taking a vital role in the modern communication networks. A routing
protocol is a protocol which is responsible to determine how routers communicate with each
other and forward the packets through the optimal path to travel from a source node to a
destination node. Among the routing protocols, Enhanced Interior Gateway Routing Protocol
(EIGRP) and Open Shortest Path First (OSPF) are the pre-eminent routing protocols. EIGRP is
a Cisco proprietary distance-vector protocol based on Diffusing Update Algorithm (DUAL).
On the other hand, OSPF is a link-state interior gateway protocol based on Dijkstra algorithm
(Shortest Path First Algorithm). In the context of routing protocol performance, each of them
has different architecture, adaptability, route processing delays and convergence capabilities.
This thesis presents a simulation based comparative performance analysis between OSPF and
EIGRP for real time applications by using OPNET. In order to evaluate
st, 2nd and
3rd network model is configured respectively with OSPF, EIGRP and combination of EIGRP
and OSPF. Our evaluation of proposed routing protocols is performed based on the quantitative
metrics such as Convergence Time, Jitter, End-to-End delay, Throughput and Packet Loss
through the simulated network models. The evaluation results show that EIGRP routing
protocol provides a better performance than OSPF routing protocol and EIGRP_OSPF performs
better than other two routing protocols for real time applications.
