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:

• Microsoft Windows operating systems
• Microsoft Office
• Mortgage finance applications
• Google Chrome browser

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.

 drawings can be created using any of the following methods:

• LibreOffice Draw Application
• 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.

Diagrams can be hand drawn or explained. Whatever works.
