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 theheadquarters in Greenwich, UK. The company has decided to perform a
simulation in case they will expand with anadditional 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, andapplications.
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 supportedservices.
Dubai Office LAN:
It consists of 25 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. 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 aresupported 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
theinclusion of graphs and justification of made decisions or the results achieved through the
simulation.
The tasks:
1. The objective is to perform

5. group
literature research.
Perform literature research on the technologies that are used in a modern network. CHOOSE 3
from thefollowing list of network technologies: -
i. 5G and WiFi 6 technologyii. Artificial Intelligence (AI) and Machine Learning(ML)iii.
Augmented reality and virtual realityiv. Cloud computingv. DevOpsvi. Digital transformationvii.
Intent-based networking (IBN)viii. Internet of Things (IoT)ix. Data Securityx. SD-WAN
There are multiple providers of such services, someexamples, are Amazon AWS, CrowdStrike
and CISCO (BUT NOT LIMITED TO). Critically discuss these technologies concerning the
scalability and transparency of communication, providing examples. Identify two or more
commercial risks arising due to the failure of such cloud services. The discussion should be
documented and should be approximately 700 words. The group should consist of two roles:
Risk
assessor:
The risk assessor evaluates the potential threats.
Upgrade engineer:
The upgrade engineer must review the technologies from a benefit point of view.

communicate with New York and Dubai offices. It is planned that 10 users will communicate
with the Dubai office and 5 users will communicate with the New York office. All offices
willcommunicate via MS Teams or Zoom. Investigate the behaviour of the MS Teams vs Zoom

Evidence of clear understanding, good analysis of the results and some critical and justified
evaluation in the conclusion. The analysis must include a graphical representation of the results
and any relevant network diagrams and identification of trends in the data. All sections are

Average
Evidence of an understanding of the networking fundamentals, some results attained and
presented. Correct but not incredibly detailed analysis, limited evaluation (but there must be
some), all sections attempted and provided.

be missing. The provided documentation must be correct. Conclusions must be included and
must be justifiable.
Poor
A poorly written report without structure. The essential elements are missing, insufficient data
samples. Little or no evidence of having devised or conducted research and experiments. Little
evidence of understanding, poor orincorrect analysis or the conclusion.
