Deliverables: Technical Design and Implementation Report

Part I — Network Infrastructure Strategy (LOI)

Objective: Demonstrate understanding and justification of a simple, real-world network design.

You should:

1. Explain the networking needs Of MediNet Systems – including data sharing, email services, and secure internet access.
2. Discuss key concepts such as:

• Networking, Transmission type, and synchronous vs. asynchronous
• Different network topologies: star, bus, mesh, hybrid – identify which topology best fits the MediNet scenario (any two)
• Network architecture: client-server vs. peer-to-peer models, and why client-server architecture is preferred for organizations.

3. Propose an infrastructure strategy for MediNet (no implementation is required here):

• Suitable hardware (router, switches, servers, PCs).
• Logical design (LAN at each site and secure inter-site connection).
• Scalability and reliability (redundant connections, simple routing).

4. Justify your choices to design your network- how well you have met organizational needs (e.g., speed, cost, security, manageability).

Part 2 – Application of Networking Principles and Protocols (L02)

Objective: Apply key networking protocols to show understanding of data communication and network operation.

You should:

1. Describe and apply networking protocols relevant to your proposed design:

• Networking protocols (TCP/IP) – briefly explain layers and how they enable communication.
• Service protocols: DNS, DHCP, SMTP, IMAP, POP, SSH, TELNET. Explain any three.
• Communication protocols: FTP, SFTP, WWW, HTTP. Explain any three.
• Security protocols: OSPF, IPSec – how they ensure secure and efficient routing.

2. Explain routing principles:

• Difference between static and dynamic routing.
• Examples of routing protocols (OSPF, RIP, IGRP, EIGRP, BGP). Explain Any two.

3. Simulation:

• Based on Part I network design in, create a simulation in Cisco Packet Tracer showing interconnectivity between the two offices using a router, switch, and client devices.
• Demonstrate IP addressing, connectivity, and basic routing (e.g., RIP or OSPF). – Include screenshots and short explanations.

Deliverables: A practical implementation plan and a network setup in a simulated environment. Note: screenshots of the design/practical work should be included in the report with suitable discussion and supported with literature. The Cisco Packet Tracer file should be uploaded as a separate file on Canvas.

Part 3: Personal Reflection

Write a reflective summary addressing your planning and decision-making process; key challenges (e.g., compliance, critical system uptime, etc); and lessons learned particularly around secure design for healthcare systems (200-250 words).

SWE4202 Assignment 2

Learning Outcomes

L03: Formulate scripted solutions to automate operating system services.

L04: Implement practical solutions based on the client/server model to solve a given problem.

Assignment Instructions

Task 1: Operating System Automation with Python (30 Marks)

In this task, you will design and implement a simple Python automation script that performs basic operating system maintenance and monitoring.

The script should combine tasks related to file management and system performance tracking.

This task builds your ability to use Python scripting to automate common OS operations — a foundational skill for infrastructure and DevOps roles.

Scenario

Imagine you are part of a small IT team responsible for maintaining computers in a shared workspace.

You have been asked to create a script that can:

1. Create and organise folders for storing logs or backup files.
2. Copy or move system logs into a backup folder automatically.
3. Monitor system performance (CPU and RAM usage).
4. Save readings into a text log file for later review.
5. Provide a short summary on the console once the script finishes.

Requirements:

Your script should:

1. Use the modules os, shutil, psutil, and datetime.
2. Create a folder named SystemMaintenance (if it does not already exist).
3. Copy or move the file system_log.txt into that folder (if found).
4. Collect 5 samples of CPU and memory usage every 2 seconds.
5. Write each sample to a new file named maintenance_log.txt, including the date and time.

Deliverables:

You must submit:

1. Python Script File: system_automation.py (must run without errors in Thonny).
2. Evidence Screenshots: console output, maintenance_log.txt, and SystemMaintenance folder.
3. Short Written Explanation (z 850 words): step-by-step description, automation explanation, and reflection on what you learned.

Task 2: Reliable File Sharing for a Small Office (30 Marks)

This task focuses on understanding the client—server model and its importance in achieving reliability, availability, and data integrity.

You will research and propose a simple, real-world solution for a small office to share files safely and reliably.

The task will help you demonstrate your understanding of how centralised systems and cloud services can improve data access and security.

Scenario

A small office wants to make sure its employees can access and share documents safely without losing files when one computer goes down.

Currently, they use direct peer-to-peer sharing, which often results in file duplication, version errors, and data loss.

You have been asked to recommend a simple improvement using a client—server or cloud-based setup that enhances data integrity and availability.

Requirements:

You are required to research how a client—server setup could improve file sharing reliability. Your report should:

1. Explain how a central server can manage data for multiple client computers.
2. Discuss the benefits of data availability, reliability, and integrity in such systems.
3. Suggest one simple cloud-based solution (for example, Google Drive, OneDrive, or Dropbox) that fits this model.
4. Identify one basic security measure (for example, authentication or encryption) to protect the shared data.
5. Include a simple labelled diagram showing how the system would work.

Deliverables

You must submit:

1. Research Report: approximately 850 words.
2. One labelled diagram showing the client—server/cloud architecture.
3. References in Harvard style for any external sources used.

Task 3: 15-Minute Technical Demonstration (25 Marks)

In this section, you are required to demonstrate your work for the Operating System Automation with Python of task 1 and the Reliable File Sharing for a Small office of task 2, demonstrating your understanding of the project, and its technical foundation.

The demonstration is expected to be clear, accurate and logically structured meeting the requirements of task I; the python code is functional and well written with comments meeting the requirement for task 2; and there is evidence ofstrong theoretical grounding from the explanation and responses to questions.

Deliverable: 15 minutes class demonstration of the work done in Task 1 and 2 above.

Declaration: At the end of the assessment you should also include a declaration of any software tools including Generative Al (GAI) applications that you used in developing and completing the assessment.
