Abstract
Routing is difficult in enterprise networks because a packet might have to traverse many intermediary nodes to reach the final destination. The selection of an appropriate routing protocol for a large network is difficult task. The focus of this work is to select and identify the best routing technique for a computer network. In this study, the performance of OSPF and EIGRP routing protocols with respect to CPU utilization is analyzed using OPNET simulator. The results depict EIGRP acquires redundant information which effect CPU utilization.
Highlights
In this present era, computer networks are growing rapidly day by day
Routing protocols are comprised into two diverse categories: Interior gateway protocols (IGPs) and Exterior gateway protocols (EGPs)
The IGPs such as OSPF and EIGRP work in an autonomous system routing whereas the EGPs work for routing among multiple autonomous systems
Summary
Computer networks are growing rapidly day by day. Communication technologies provide user convenient services such as file sharing/transferring, printer sharing, video streaming and video/voice conferencing. Internet plays an important role in todays communication networks which are based on technology that provides the technical infrastructure. In this technical infrastructure routing protocols are used to find an efficient route to transmit packets across the internet. In WAN, IP packets are being forwarded by the routers For this purpose the routing devices use the routing protocols which determine and select the best path to forward the packets [1]. Communication among different routing protocols depends on routing algorithms which base on the nodes to determine the route to forward the packet over networks [2]. Our effort in this research is to investigate the IGPs so the purpose of this investigation is to examine the OSPF and EIGRP regarding traffic-load and CPU utilization by nodes
