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, 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-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. [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 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.
