INDP Final Project
Kudler Fine Foods is an upscale food store that is located in the San Diego metropolitan area. There are three locations, La Jolla, Del Mar, and Encinitas, that make up this company. With each store there is approximately 8,000 sq. ft. of space that is located in fashionable shopping centers. Each of the stores are stocked with fresh produce, meat and seafood, and bakery and pastries. In order to better serve their customers Kudler Fine Foods is looking to tie all three of the stores into one wide area network (WAN). They are also looking to include a wireless local area network (WLAN), and add Voice over Internet Phone (VOIP) to the multi-store network. KFF wants to define just which store will house the central servers and to design the network to be expandable beyond the existing stores. Network Characteristics

Each store has a 100 Base T Ethernet connection on a bus topology that connects all equipment to the Internet. Each store also has two routers that are behind firewalls, one that has a dedicated OC 1 SONET connection and the other router is a 25Mbps connection to the Internet. Del Mar and Encinitas stores have a POS server and an HP Blade Server 3000 system that runs on both UNIX OS and LAN OS. The blade servers that are used in these stores are communications, email, storage, and web. Each of these stores also have an HP LaserJet multifunction printer for managerial use. The La Jolla store uses all of those blade servers and also uses a print/file server as well. Along with the blade server storage the La Jolla store also uses a network attached storage (NAS) that is attached with a fiber link. The software that the La Jolla store uses is UNIX OS, SAP Retail software, and NCR POS management software. The La Jolla store is using an APC Smart UPS that is 5000VA/208V. This device has an estimated run time of 14 hours and three minutes and is used to support the entire server room. Data Requirements

In determining the data requirements we first need to look at the type of topology that is in use currently. The current topology of each of Kudler Fine Foods stores is a bus topology. They use a 100 Base T Ethernet connection to be able to connect not only to the Internet but also to connect to the corporate store. The connection to the corporate store is a fiber link that is provided by the internet provider. This is a direct connect that goes to each of the stores to be able to better supply each store with information that is needed to be able to complete daily tasks. In order to ensure that each workstation has the proper speed there will be switches put in which will enable each workstation to have the same speed to be able to complete their work in a quick and efficient manner. This will also be good in incorporating the VOIP phones into the network. With each workstation having the highest speed they can possibly get will mean that each VOIP phone will have the same connection as the workstation. Communication Protocols

A communication protocol explains how blocks of data are sent from one point in the network to another. Without these protocols in place information that is sent from one store to the other runs the risk of not making it to the destination because packets of information could be lost in the transmission. The protocols that Kudler Fine Foods is using are TCP/IP protocols. The protocols that are in use for the WAN in Kudler Fine Foods are the Synchronous Optical Networking (SONET), and Integrated Services Digital Network (ISDN). The SONET connection will be used because of the high speed connection and the high bandwidth. With this protocol there will be enough speed for each of the stores that are established currently and enough to be able to expand the network if more stores are added. The wireless protocols that will be used will be the IEEE 802.11n...
