This diagram depicts the typical devices in a Dunkin’ store, and how the network is set up. The public network is separated from the business side. Firewalls are placed to keep the business network secure from public and untrusted traffic, and the public network secure from other outside traffic.
The Main Site Diagram depicts how the headquarters of Dunkin’ is set up. There are many different departments, which put strain on the network to keep up with the large number of devices. There is even a DMZ so that the business can access the internet without having to worry about the local network being compromised to untrusted network traffic.
This is the site-to-site diagram of the different Dunkin’ sites. They are represented by cell towers, since there wasn’t an icon for a LAN site that could be used. Information such as the addresses and IP addresses are stated.
