Description of the assessment

You are provided with a hypothetical networking scenario. Whilst the scenario is hypothetical and not based on any existing supplier, customer or network design, the concepts covered are real and encountered by network designers on an almost daily basis.

The aim of this assessment is for you show your understanding of fundamental network concepts to design a basic IPv4 based network that will satisfy the scenario.

To achieve this aim, you will need to complete the following objectives:

1) Understand and explain the function of fundamental network devices including firewalls, routers, switches and wireless access points

2) Understand the use case, advantage and disadvantages of various types of communication media

3) Create a logical network diagram showing the interconnection and interaction between network devices and terminal equipment  

4) Modify a physical building layout diagram to indicate the location of equipment and interconnection systems

5) Understand IP addressing, address division and address allocation methods

6) Understand the basic advantages and disadvantages of network scaling

Assessment Content

Background / scenario:

You are employed by a Networking Consultancy who design and implement networks for multiple clients. Your department of the consultancy provides general design and layout services.

Physical installation of equipment cabinets, equipment, cabling and containment will be completed by an external contracting company who will install exactly to your instructions.

The configuration of the networking equipment will be conducted by a separate external contractor who provides Technical Configuration Services. They will configure the equipment that you specify and that has been installed by the contract installation company under your instructions.

You need to complete the missing information in a report that supports the lead network engineers who are designing a local area network for the given scenario (please find more details in the case study section which you should read entirely). The Network Engineering Team have completed the majority of the work but require assistance with some of the detail and explanation.

Note for absolute clarity: The scenario and organisations are totally fictitious and have no relationship to any organisation either past or present with the same or similar name. Do not waste time or effort attempting to identify any real organisation.

For the introduction to the assignment, use only the information that has been provided in this specification.

Case study - Local Area Network Design:

Compliance with Requirement

This document has been prepared on behalf of the client, Kedleston University. This is a new building without a previous network installed. The client has conducted an extensive internal review and has defined their requirements. These requirements are fixed and not negotiable however the client will consider any informed advice offered by the designers for incorporation into a revised specification. The fabric of the building layout cannot be changed.

Introduction

The LAN will form a central part of the Information Technology strategy. It is expected to be fully operational for at least the next five years.  Any and all networking components must be available as new spares during the lifetime of the network.

The proposed solution should cover all points mentioned in this document and will consist of diagrams and tables with short descriptions of key points.

General requirements and IT usage

Each member of staff in the school will be allocated a desktop machine running Windows 11. This will be a standard system provided by a contract supplier. You are not required to provide hardware or software specifications for the machines, you are only required to provide a network connection for each device.

Lecturers will also be provided with laptops or other mobile devices that will be able to connect to the network anytime and anywhere within the campus. Students will be allowed to use the wireless network to access publicly available content using their own laptop or other devices.  

The school currently consists of staff offices and 6 computing laboratories, the layouts of which are shown in this document, the layouts are not to scale. Each member of staff and each student position will require a hardwired network connection point to attach a desktop workstation. The PC and patch cables will be provided by the University IT team once the network installation is complete.

A number of network attached dedicated hardware servers will also be provided and installed by the University IT team after the network installation. These will provide directory services, DHCP, DNS, Email, intranet, print services and database services. Once again, you are not required to provide hardware or software specifications for the machines, you are only required to provide a network connection for each device. The network design must include a location and connection method for the servers.

The network should provide flexible connectivity options throughout the site for a wide range of end systems including printers, host computers and fileservers. It should also be capable of supporting streaming content as well as voice and video communications over the LAN. The design must consider potential future requirements of increased user numbers, higher traffic loads and developing technology.

The LAN should be resilient, secure and cost effective.

LAN Segregation Requirements

The staff will be sharing the same physical network infrastructure. The network will provide access to external email and the general Internet for every attached workstation.

Each department / functional area will be a functional LAN broadcast environment, logically separated using IP subnets. The design must clearly show how the LANs will be able to interact with each other. Where inter-LAN communication restrictions are required, these will be implemented by University IT staff after the network handover.

For the sake of clarity, logical separation means that each of the departments / functional areas has its own IP subnet.

As part of this project, you will be required to create a table of IPv4 network address information based on a range provided by the client and included in the template.

General Staff

General staff are mainly lecturers and teaching assistants. The number of staff in each office is illustrated in the site layout. Each lecturer will have their own workstation with logical access to necessary servers including file storage and print servers. The General Staff network is logically separated from all other networks.  

Administrative staff

The admin team provides support to the lecturers and students. They also have a workstation with logical access to necessary services including file and print. The Administrative Staff network is logically separated from all other.  

Student Laboratories

The number of desk positions for the six student labs is known however the final layout is not yet defined. The requirement for the labs is to provide adequate connectivity and explain how a number of different layouts could be accommodated without causing trip hazards or other Health and Safety concerns.

The labs are split into five subject areas for Networks, Computer Science, Computer Games, Digital Forensics and Cyber Security. Each subject area network is logically isolated from all other networks but has access to the file and print services.

Technicians

Each technician has a desktop PC. The technicians network is logically isolated from all other networks but will need to have logical access to all networks for maintenance and support.

The technicians will need physical access to networking equipment as and when required. The technician’s area has a large storeroom which, although currently unoccupied, has multiple power connections available and an installed key card locking system.

Guest Network

A guest network is required for visiting clients to access the network from their mobile devices. Visitors will have secure and monitored connectivity to the Internet but will be denied access to the majority of the internal networks. This restriction will be implemented by the University staff.

Physical layout of the site

The diagrams below show the physical arrangement of the rooms over two floors. The diagrams are not drawn to scale but do suffice to illustrate the layout. It will be reasonable to assume that no room will be larger than 15m x 15m x 4m. The height of 4m includes a 1m ceiling void above the false ceiling height. The diagrams are shown in Figure 1 and Figure 2 at a reduced size and replicated full size in the template file.

The number in brackets indicates the number of people that will occupy the room.

Logical addressing – the IP address table

The number of physical connections in any network does not directly relate to the number of logical addresses required in that network. You are given a list of required numbers of IP addresses for each network, you should design an allocation table that uses the minimum number of addresses that will satisfy the requirements.

Figure 1: Ground floor layout

Figure 2: First floor layout

On completion, the final installation will be professional in appearance and allow for future changes including expansion with minimal service disruption and at minimal cost.

Your Deliverable – A report detailing your proposed solution

You have been provided with a template report structure. The template contains clarification of the requirements in each section.

This assignment is not a test of what you remembered from the lectures, it is a test of your ability to utilise the information that you possess in order to expand your knowledge and capability.

Researching information and validating understanding is not a failure in your abilities, far from it. Researching proves your interest and intent to succeed academically and commercially.

Your finished proposal must satisfy the requirements and be professional in appearance.  

Your report explains your work, this is the item that is marked, if you do not explain clearly then any work completed will be in vain. The report should explain what you are doing, why, provide the technical detail of the solution, summarise the solution and justify the content.
