PERFORMANCE ANALYSIS OF ROUTING PROTOCOLS IN A SIMULATED ENTERPRISE NETWORK
Abstract
This study presents a simulation-based performance analysis of OSPF,
EIGRP, and RIPv2 routing protocols with emphasis on network overhead
in a simulated enterprise network. Using Cisco Packet Tracer, each
protocol was implemented on an identical network topology and evaluated
under steady-state and link failure conditions. Network overhead was
measured based on control traffic, bandwidth consumption, and protocol
behavior during topology changes. The results show that EIGRP generates
the least network overhead due to its partial and event-driven updates,
making it the most bandwidth-efficient protocol. OSPF exhibits moderate
overhead with good scalability, while RIPv2 produces the highest
overhead because of its periodic full routing updates. The study concludes
that EIGRP is best suited for bandwidth-constrained enterprise networks,
OSPF is appropriate for large structured networks, and RIPv2 is suitable
only for small networks.
