Performance evaluation of a wired network with & without Load Balancer and Firewall

This paper presents the WAN performance in low load campus network with & without Load Balancer. In this network model, generic LANs models are used and impact of increased FTP load on the network performance are investigated. In this paper, a simulated environment is created where many applications are in use at a time and their mutual effects thereof. This network model is based on OPNET IT GURU Academic Edition. This OPNET is used to develop a new model suitable for Campus/University environment. This model is tested against various types of applications (FTP, ATM, Remote Login, and Print) in 5 LANs and found that among a set of parameters with and without Load balancer, Firewall and IP cloud. This OPNET simulation showed the impact of load balancing on WAN for different types of applications.
