The coursework detailed specification:
This is an individual assessment. Your investigation should not be shared among other students.
The objective of the coursework is to simulate a client-server model communication over an IP network and to investigate an application and network performance in multiple provided scenarios.
This assessment requires to use NetSim simulator.
The network architecture overview:
The company’s headquarters are in Greenwich (UK). They have recently opened regional offices in New York (USA), and Dubai (Dubai). The main service provided by the New York and Dubai offices will be gathered and distributed monthly and annual reports describing sales managed by the headquarters in Greenwich, UK. The company has decided to perform a simulation in case they will expand with an additional call centre.
Greenwich HQ LAN:The network is undefined and needs to be designed by the student with justifications, this implies justification of several nodes, users, and applications.
New York office LAN:It consists of 35 users connected to a core switch, Local printer, and email. They are connected to the Internet via a backbone link. Some application.

This assessment requires to use NetSim simulator.
The network architecture overview:
The company’s headquarters are in Greenwich (UK). They have
recently opened regional offices in New York (USA), and Dubai
(Dubai). The main service provided by the New York and Dubai
offices will be gathered and distributed monthly and annual
reports describing sales managed by the headquarters in
Greenwich, UK. The company has decided to perform a

centre.
Greenwich HQ LAN:The network is undefined and needs to be
designed by the student with justifications, this implies
justification of several nodes, users, and applications.
New York office LAN:It consists of 35 users connected to a
core switch, Local printer, and email. They are connected to the
Internet via a backbone link. Some applications run by users
including printers and databases are local and others like web
browsing and MS OneDrive are supported including remote
desktops, in Greenwich, UK. Additionally, 8 users work from
home using MS Teams & Zoom with all supported services.
Dubai Office LAN:It consists of 25 users connected to a core
switch, Local printer, and email. They are connected to the
6. Internet via a backbone link. Some applications run by users
including printers and databases are local and others like web
browsing and MS OneDrive are supported remotely, in
Greenwich, UK. Additionally, 8 users work from home using
MS teams & Zoom for voice and video calls.
Network Operations Centre (NOC): It would consist of 15 users
connected to a core switch, Local printer, and email. They are
connected to the Internet via a backbone link. Some
applications run by users including printers and databases are
local and others like web browsing and MS OneDrive are
supported remotely, in Greenwich, UK. All users run MS Teams
& Zoom conferencing applications with Dubai Office.
The tasks:
The objective is to perform group literature research,
individually build a NetSim simulation model based on the
network architecture given and evaluate the behaviour of
network parameters gained by simulating the use cases. The
design, implementation and simulation discussion imply the
inclusion of graphs and justification of made decisions or the
results achieved through the simulation.

Project Description:
You manage a housecleaning service. As manager, you schedule
the cleaners with clients, provide cleaning supplies, and insure
the cleaners. You pay the cleaners for their time and mileage
reimbursement. You set up a monthly workbook with one
worksheet per week to enter the dates, mileage to each house,
and start and stop times. You then calculate the hours worked.
You are ready to calculate weekly totals and the monthly totals.
