6. Evaluate a range of information comparing alternative methods and techniques used in Network Design.

7. Be able to troubleshoot and maintain integrated, complex networks.

This assignment will assess the following learning outcomes:

1. Demonstrate a broad understanding of the knowledge base of this module, and its terminology and discourse

2. Evaluate network devices to be used for a particular area in the network in relation to requirement

3. Design and implement a fully functional network infrastructure based on requirement given in the assignment brief

4. Demonstrate autonomous learning context and draw on prior experiences reflecting and evaluating on new leaning outcome.

Scenario

You are working as a network engineer in an IT company. You have been assigned to design, implement a network infrastructure for a small company donow.co.uk. The company consist of 4 departments (finance, engineers, sales and IT).

The network consists of three Servers: web-dns, email- IoT, and common File Server as described in the table below. All servers are shared between all users. The distribution of workstations, shown in table 1, describes the requirement of each department. The company has decided to allow members of staff to use the wireless network on their own wireless device such as smartphone to access the internet.

Department Devices Requirements

Finance 8 Computers cannot access any other department Sales 31 Computers & Printer cannot access any other department Engineers 21 Computers & printer cannot access any other department IT 3 computers cannot access any other departmentWireless Devices Should be sufficient for

1-web-dns server

1 email-IoT server

1 common File Servers

Accessible by all computers

IoT devices To monitor temperature / thermostat cooling, and server room door.

Table 1: workstation and server distribution and requirements

The IT director emphasised on scalability and availability, hence you are being required to provide a complete network infrastructure design and implementation. The company will be using private network IP address 192.168.44.0/24 within wired LAN, and 10.20.44.0/24 for the wireless network.

Task

Analyse the requirements given in above scenario evaluating suitable network models and components to design a network infrastructure featuring scalability, availability and security. Based on your analysis and evaluation, you are to:

Scenario

· Apply the required configuration for the selected components.

· Discuss, evaluate and apply Network monitoring tools/components, and

· Produce network test and documentation suitable for network maintenance.

All relevant network configuration, network diagram and device configuration tables, network simulation file must be included and attached as appendix.

· Complete network diagram for the given scenario, including description and analysis.

· Appropriate subnet showing all required elements, based on given network addresses, are fulfilled.

· Create VLAN for each department based on given requirements, including sample configuration.

· Justification of the use of network design model and components including any technologies/protocols used such as VTP, STP, DHCP etc..

· Provide complete security precaution and configuration where applicable including Accesscontrol list to isolate each department internally.

· Complete testing documentation of all relevant devices such as web, email, DNS servers, (note: use of screenshots without description is not acceptable as answers)

You need to state the word count at the end of their assignment. 10% over the stated word count is permitted without penalty.

If students go beyond this, then there is a penalty of 5 marks for every additional 10% beyond the word count with a maximum of a 15 mark penalty reduction.

There is no specific penalty for submitting a piece which is below the word count, but please note that shorter submissions are likely to attract poorer grades, particularly where they lack the necessary depth of analysis.

How do you calculate the word count?

The word count includes the Abstract or Executive Summary and all in-text citations. The word count does not include the Bibliography and Appendices. Please note that Appendices should only include supplementary information, not information critical to your work.

Introduction to the context and/or background to the topic, indicating the purpose of the report

The introduction includes some definitions of complex terminology or acronyms and indicates ideas in view of the conclusion of the report.

Demonstrate effective approach to study and research including explanation and discussion of subject concepts, exploring functional and non-functional requirements of the given assignment

Use relevant information paraphrased / interpreted from academic sources, summarise and make sense of information

Applying knowledge and analysis

Discussion, examination and analysis of different network components, exploring the relationship between different components

Reasoning of device/components selection based on prior-knowledge, backed by evidence of research from sound sources

Discussion and analysis of different network models Evaluation and judgement

Task

Evaluation of different components and network model

The judgment in selecting components shows understanding of issues based on evaluating and comparing different network components supported by literature

Evaluation of different technologies and/or protocols such as VLANs, Trunking, Access control, DHCP etc.

A description of network diagram, summarising the network design, including implementation and configuration of all network components and protocol with evidence (sample network configuration scripts).

The plan accommodates the necessary devices and accounts for the unforeseeable conditions.

Evidence related to the work is carried out in designing. Implementation is apparent and demonstrates autonomy and independence.

A well-defined document that reflects testing of given requirements, protocol, and selected components used.

Demonstrate and present network testing using appropriate technical language evidently related to the work carried

Assignment Preparation Guidelines

· All components of the assignment (text, diagrams. code etc.) must be submitted in ….one-word file (hand-written text or hand drawn diagrams are not acceptable), any other accompanied materials such as simulation file, code, etc. should be attached in appendices.

· Standard and commonly used fonts such as Arial or Calibri should be used, font size must be within the range of 10 to 15 points including the headings, body text and any texts within diagrams,

· Spacing should not be less than 1.5

· Pay attention to the Assessment criteria / Marking scheme, the work is to be concise and technical. Try to analyse, compare and evaluate rather than simply describe.

· All figures, screenshots, graphs and tables must be numbered and labelled.

· The assignment should be logically structured, the core of the report may start by defining the problem / requirements, followed by the proposed solution including a detailed discussion, analysis and evaluation, leading to implementation and testing stage, finally a conclusion and/or personal reflection on learning.

· Screenshots without description / discussion does not constitute understanding and maybe assumed irrelevant.

· Please access your Turnitin Test Page via Dashboard or My modules to learn more about Turnitin and to make a test submission and to check your similarity score before uploading your final version

· You will have opportunity to submit as many times to your module pages as you want up until the deadline.

· Make sure to make backup of your work to avoid distress for loss or damage of your original work, use multiple storage media (memory stick, cloud and personal computer).

· Please note file size limitation might apply. You work must be under 100MB. Assignment support:

· During the delivery of the module, you will have several opportunities to get formative feedback on your assessment during tutorials.

· Although you will be guided throughout the module by your lecturer, you can get extra support for your assignment, just make an appointment with the ACE team for any language, research and study skills issues and/or talk, email the Computing ACE expert for any advice on how to approach your assignment. REMEMBER: they are not here to give you the answers!

· Students will have access to formative feedback on each task set in workshops, thereby helping them to refine their approach to the summative tasks that have been set.

· However, please note that this feedback is limited to recommendations on improving your work. Lecturers will not confirm any grades or marks.

· The feedback can be one-to-one or in-group sessions.

· Finally, you will receive summative feedback within 20 working days of your final submission. Please note that the summative feedback and the grades remain provisional until approval from the exam board.
