Introduction

Kudler Fine Foods is in need of a network overhaul, they want to design a WAN to integrate three different locations together and make the internal network in each store a Wireless Local Area Network. Also, they have requested Voice Over Internet Protocol at each multi-store node on the network. There are various protocols which will make all this happen: Transfer Control Protocol and Internet Protocol are the base of data transfers. TCP is the protocol in which internet, email and file transfers are built. A couple of other protocols designed to process packets throughout this new network are X.25 and Frame Relay. Frame relay was based on the X.25 protocol and reduces the amount of overhead associated with data transmission, allowing for quicker packet switching methods. This network will use a T1 line to reach the required bandwidth to support the configuration for which Kudler desires. If the network traffic is heavily congested it will be controlled allowing for more streamlined communications between the nodes on the network. Frame relay’s overhead reduction is due to the use of a specific fast packet switching technology, flow control and error correction are what determines the efficiency of the faster packet switch. In the OSI model, which divides the network communication into seven layers, where each layer describes the various protocols and function. Frame Relay excludes any third layer protocol because the operation gets performed on the second layer. The initial setup will be that of a ring topology.

The system will need to be updated in a manner that will allow for near seamless future updates as well as being brought up to current technology standards. The goal of this project will be to design a Wide Area Network (WAN) which will tie all three Kudler Fine Food locations together. There will be an internal network...
