You are to create a high$-$level network design for a new mortgage finance company. Your design must facilitate a basic understanding of the network and its operation. A public MAN is used to connect the main office to the local branch office. A WAN is used to connect the main office to the remote branch office. The network is connected to the internet.

You must produce a single PDF document that contains the following sections:

Introduction

Requirements

Diagrams

Descriptions

Message Flow

Troubleshooting

Use Microsoft Word or PowerPoint $($or their equivalents$)$ to create the document. When you are ready to submit it$,$ save it as a PDF file and upload the PDF$.$

The content requirements for these sections are outlined below:

Introduction

This section should include:

Your name

A statement that this project is your own work

First paragraph from the above Scenario section

Requirements

The network includes the following locations:

$1$ main office in a metropolitan area

$1$ local branch office in the same metropolitan area

$1$ remote office too far away to connect to the metropolitan area$$s MAN

Each office contains an identical LAN:

$1$ manager workstation

$5$ customer service representative $($CSR$)$ workstations

$2$ shared printers

Ethernet protocol

Each office includes wireless communication:

$2$ wireless access points

The company uses the following software:

The network contains the following servers $($located at the main office$)$:

$1$ application server

$1$ web server

The network includes the following security components:

$1$ edge firewall $($to protect the company from the internet$)$

An intrusion prevention system $($IPS$)$

Norton anti$-$virus software

Assumptions

Your design will be at a higher$-$level than specific floor plans.

Someone else will map your design to specific floor plans.

You must decide the bandwidth and cabling types for the various network connections.

You must decide where routers and switches are used.

Diagrams

This section contains the following physical network diagrams:

$1$ high$-$level diagram showing the inter$-$building connections via the MAN and WAN

$1$ diagram showing the common LAN

$1$ diagram showing the distinctive office features

All hardware components mentioned in the requirements must be shown.

Do not show software components.

Your drawings can be created using any of the following methods:

LibreOffice Draw Application

Microsoft PowerPoint

Microsoft Visio

Another diagramming tool of your choice

Neatly hand$-$drawn, clearly visible, scanned images

Descriptions

Describe the components mentioned in the Requirements section.

Include both hardware and software components.

Order your components in alphabetical order.

Each description must clearly communicate:

The purpose of the component

The main functions of the component

Any special inter$-$relationships this component has with other components

Message Flow

Select a communications path between any two network endpoints.

Select a type of message that is part of that path's traffic.

Describe its general message flow across the layers of the TCP$/$IP protocol stack.

This should include the layers on both the sending and receiving sides.

Describe the function of each TCP$/$IP layer as it relates to your chosen message.

Include a diagram that relates the TCP$/$IP layers to their corresponding layer$($s$)$ in the OSI model.

Troubleshooting

Identify $2$ network troubleshooting scenarios. For each, discuss the strategies and tools you could use to research and resolve them.$$

You must take a screenshot of at least one of the tools discussed in this section.

Include the screenshot in this section.
