COMP1664 Network Technology: Riverbed Modeler & Network Performance

This project focuses on designing and using Riverbed Modeler to investigate factors affecting network performance for a medium-sized company, XYZ hospital. The project is divided into three parts: designing and modeling the network, evaluating its performance, and investigating the network's behavior to understand its performance and configuration. The network design incorporates a tree topology with client-server architecture, Ethernet, routers, and duplex-1000Base links. Network traffic modeling includes IP-based cloud technology for internet access and utilizes FTP, HTTP, and database applications for various departments like HR, IT, and medical. The performance investigation explores throughput and data reception with varying user numbers and access points, revealing that fewer users lead to more successful data transfers. The project concludes by highlighting the advancements in computer networks and emphasizing the importance of outlining the network, modeling it with relevant tools, and discussing the results for effective network performance investigation.

Introduction
 To design and use riverbed modeler to investigate
the factors which affect network performance
 Part A: designing a network for a medium sized
company and modeling it.
 Part B: evaluating the performance of the network
 Part C: investigating the performance of the
network so as to understand its performance and
network configuration.

Part A: Designing and modeling it
Overview of XYZ hospital
XYZ hospital is an organization which
specializes in treating cancer patients
 The company has over 100 employees
divided into various departments which are
the IT department, Finance department, HR
department, and the medical department

 The organization is located in a three-floor
building where the finance and the two secretaries
are located in the ground floor, medical team
department in the second floor, HR department is
located in the third floor
 Everyone is required to connect to the organization
campus LAN for internet access and to access the
shared resources
Network design needs: XYZ

Network topology
A topology in networking is the
configuration of peripherals, cables, and
computers.
This has utilized tree topology
 Tree type of topology is a type of network
topology whereby elements or devices are
arranged like branches in a tree (Krawetz,
2014)

Network technologies utilized
 The technologies which have been utilized are:
 client-server,
 Ethernet
 Ethernet workstation
 routers
 Ethernet-servers.
 A link type, in this case, is duplex- 1000 Base

Part B: Network Traffic Modeling
 no security which was imposed on the XYZ network
when designing this scenario
 IP based cloud technology will act as the internet which
connects the organization to the wide area network.
 Two network routers are used to connect across the
network simulation.
 Three different applications utilized in this scenario
which are FTP, HTTP, and database applications for
each department.

User profiles
The HR department is mandated in
managing employees’ data
The IT department mandated to
maintain the organization network
The medical department mandated to
keep patient records

Justification of User profiles
The various departments have transfer
files, use email on daily basis and use
XYZ database. This means that the
following application are required
 FTP application
 Email application
 Database application

Justification of User profiles
The various departments have transfer
files, use email on daily basis and use
XYZ database. This means that the
following application are required
 FTP application
 Email application
 Database application (Rendell, 2013)

Configuring the Http application
 To configure HTTP application in riverbed one ought to
select built-in models and pre-set configurations; for this
scenario, heavy browsing was selected.
