CourseworkDeadline Date:Monday 04/12/2022This coursework should take an average
student who is up to date with tutorial workapproximately 50 hours Feedback and grades
are normally made available within 15 working days of the coursework deadlineLearning
Outcomes:A. Demonstrate knowledge of network communication, OSI and TCP/IP model.B.
Demonstrate a critical understanding of the top network model with related key protocols,
services, and applications.C. Evaluate common network problems (malfunction, poor
performance), and adopt a systematic approach to troubleshooting and resolving the
problem.D. Be competent in the use of tools designed to analyse and simulate network
functionality.Plagiarism is presenting somebody else’s work as your own. It includes
copying information directly from the Web or books without referencing the material;
submitting joint coursework as an individual effort; copying another student’s coursework;
stealing coursework from another student and submitting it as your work. Suspected
plagiarism will be investigated and, if found to have occurred, will be dealt withaccording to
the university’s procedures. Please see yourstudent handbook for further details of what
is/isn’t plagiarism.All material copied or amended from any source (e.g., internet, books)
must be referenced correctly accordingto the reference style you are using.Your work will
be submitted for plagiarism checking. Anyattempt to bypass our plagiarism detection
systems will be treated as a severe Assessment Offence.The coursework detailed
specification:This is an individual assessment. Your investigation shouldnot be shared
among other students.The objective of the coursework is to simulate a client-server model
communication over an IP network and to investigatean application and network
performance in multiple providedscenarios.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 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,

2. 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 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-WANThere 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. [GROUPTASK] 10%2. Design,
implement and simulate your model in the NETSIM simulator guided by the given network
architecture overview. The design requires detailed documentation on the application and
performance settings in the NETSIM simulator for each user and these settings
justifications. Following the implementation, you are required to simulate yourscenario.
[INDIVIDUAL TASK] 20%3. The documentation must contain subnetting schemes for each
LAN/WAN/MAN. Note: You should configure NetSim to use these subnets. You must
provide the following: Network Address, Broadcast Address, Usable Addresses, and IP
Address assignments to hosts. You must use at least two classes from the PrivateAddress
Space. [INDIVIDUAL TASK] 20%4. Investigate the behaviour of the network performance in
a variety of cases. The analysis must be done regarding your expectations. Discuss the
scenario and hypothesize on the possible outcomes of provided use cases followed by the

3. analysis of the results that werereceived from the simulation. [INDIVIDUAL TASK]20%5.
You must review the following [INDIVIDUAL TASK]20%:i. Utilization of the backbone link.ii.
Cloud Storage (OneDrive) average file download timeiii. Web Server page response time.iv.
The behaviour of MS Teams/Zoom applicationsv. Ethernet delay on the network
(bottlenecks)vi. Simulate the following use case: The new NOC will 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 in the given
scenario.vii. Evaluate the network performance in a use-case, where you would introduce at
least one of the improvements that you have identified.6. Provide a critical reflection on the
tasks you carried out.[INDIVIDUAL TASK] 5%7. The document must include your
concluding comments.[INDIVIDUAL TASK] 5%Note:Perform the analysis of the results
starting from the first minute. This should be done, to reduce the noise from the data caused
by the initialization of network devices such as routers and switches which may have an
impact onyour investigation.The group assessment should be completed in pairs and
mustinclude the following: –1. You must provide the names of all participants who
contributed to the group work.2. Your submission must include exact copies of the
groupwork.Deliverables (No more than 3000 words):A good structure report must include
the following:• A literature review on the technologies used in a provided network
architecture and the benefits ofusing cloud services. Refer to Task 1.• Description of the
designed and implemented scenarios, including the justifications for the design and choice
ofperformance parameters. Refer to Task 2.• Documentation on the investigation of
required features and use cases, including graphs and analysis of the results of the
simulation. Refer to Tasks 3, 4, and 5 and the subcategories.• Based on the results;
recommend your choice of consideration to improve the network model.• A critical
reflection that is both evaluative and reflective.Refer to Task 6.• Concluding comments.
