Effectiveness of Routing Protocols for Different Networking Scenarios
Advances in Science, Technology and Engineering Systems
Selection of a routing protocol is vital for modern arena of Internet communication as network traffic and network complexities are rapidly increasing. This paper evaluates the effectiveness of three routing protocols namely routing information protocol version 2 (RIPv2), open shortest path first (OSPF), enhanced interior gateway routing protocol (EIGRP), and hybrid protocols based on these three. These stand-alone and hybrid protocols are compared in terms of four metrics: throughput, jitter,
... hroughput, jitter, packet length and packet loss. Different kinds of networks are developed using Graphical Network Simulator-3 (GNS3) network software emulator. The network performance measurement of those four metrics is done with the help of Wireshark and Iperf tools. Besides, three network topologies termed as 'experimented ', 'retracted' and 'extended' networks are created using 7, 3, and 9 routers. Simulation results indicate that EIGRP protocol performs the best showing the highest average throughput (28 packet/sec), while RIP-OSPF hybrid protocol has the lowest average throughput (16 packet/sec). Moreover, EIGRP has the lowest value of packet loss of 2.66. The lowest jitter value is obtained for hybrid RIP-OSPF-EIGRP protocols. However, EIGRP has a moderately high jitter value. Furthermore, EIGRP has standard size of packet length. Hence, EIGRP can be a good selection as a routing protocol for different sized networks.
