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.

Part B: Network Traffic Modeling

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.

Configuring the email application
 To configure email application high load was used

Part C: Network Performance
investigation
 The goal of this part is to find out throughput and
data receive with a different number of users and
number of access points.
 This scenario tested for 3 different organizations
subnets which are 50 users with 1 APs, 50 users
with one AP and 50 users with 2 Aps
 Along figure shows network overview of the
scenario

Cont..
 To explore the relationship between each network
performance and the number of users we picked the
first and third scenario; the one which has only one
access point and using the same application. The first
had 50 users in a subnet using 1 AP and 50 users using
2 APs.
 application utilized in here was video conference which
preset to high load. The simulation time was five
minutes and simulating running time was 10 minutes.

Cont..
 Diagram Delay comparison
 Figure alongside shows Throughput comparison
for different users

Cont..
As one can view from delay comparison
and throughput figures the less the number
of users then the more data transfers are
successful to the next layer. If one was to
map this data into excel the following
would be the output
Hence the graph alongside can be
generated

Conclusion
The computer network has undergone a lot of advancements
since its inception.
In this project network delay or data, delay points out to only
one indicator which is the number of users.
This paper has also discussed the steps which one can use when
investigating the network performance of an organization which
is a three major process as discussed in this paper which are:
 First entails outlining the network of the organization
 Second is modeling it through the relevant tools available
 Third discussing the results.
