INSY 3303 Lab 04 Manual
Lab 1: Improving performance by LAN Hardware Upgrade
Objective
In this lab, OPNET’s IT Guru Academic Edition advanced modeling software will be used to study performance improvements in LAN obtained by upgrading switch hardware. We will also look at a wireless LAN topology and characterize it by looking at Media Access Delay values.
You will learn the benefits of upgrading switch hardware in a congested LAN environment. Lab Project
Friendly Care Hospital is one of the biggest hospitals in DC. It owns a 5-story building, and houses many departments that span multiple floors. Its Radiology department is spread across the first and second floor connected by a dedicated
LAN. The department has recently deployed a new “Radiology Images” application as part of their initiative to digitize patient records. However, the department staff sometimes faces long application delays during busy hours.
You, as their network engineer, are tasked with the job find the cause and recommend a solution. Also, Friendly Care is looking to design a wireless hospital for the future and wishes to study a proposed network design, using a completely different topology and traffic profile.
Overview
In this lab, there are 3 scenarios. The first two scenarios study the “Radiology
Images” application performance on a 100 Mbps switched Ethernet network, and a 1 Gbps switched Ethernet network after a switch hardware upgrade. The third scenario focuses on evaluating a Wireless LAN, including low-level Media
Access Delay (MAC) statistics, and high-level performance statistics like application response times.
