    • FEASIBILITY STUDYSituation in which the Project Exists:This proposal is for a data communication network toserve for Saigon Restaurant. The company has been trying to expand their network across theirthree offices. The company has been approved funding sufficient to pay for the development ofthis proposal. The proposal is still pending on the acceptance of Saigon’s Department ofTechnology to grant us funding for implementation.Network Scope:The proposed network is designed to serve Saigon Restaurant and two of itsbranches. The headquarters, located in St. Paul, MN, contains four departments to be served bythis network. Each branch contains two departments to be served. The North branch, locatedinDuluth, MN isabout 134 miles from headquarters. The East branch, located in Madison, WI isabout 222 miles from headquarters. This network is for administrative purposes and isspecifically designed to be independent of student computing facilities.Objectives of the Network:The network is designed to achieve several specific business andoperational objectives:Secure Service: The main objective of this network is to provide secure administrativecomputing service to Saigon Restaurant and two branches. It is designed to be functionally andphysically isolated from access by people not employed by Saigon to minimize the risk ofunauthorized use.Integration and Update: There are many LANs in Saigon Restaurant’s system, but much of theequipment is out of date. Many which are incompatible with each other and are not connected inan enterprise-wide network. This proposal will integrate a WAN that will update these LANs tosupport productive collaboration across the system.Information Processing: The network will enable users to retrieve, process, and store variousinformation across the network; graphics, audio, and video from any computer connected to thenetwork.Collaboration: The network will be able to provide the collaboration between each location. Thiswill enable users to share information and ideas easily across the network so they can work moreefficiently.Scalability:This design will allow future branches to easily be added without having to redo theinstalled network.Network Design Proposal Page | 2 Yang
    • Intended Users:The main users for the network at headquarters are: two managers, threemembers of the Human Resources Department, four members of the Finance/AccountingDepartment, and three members of the Information Technology Department. At the branch level,the main users will be one manager, two members of the Finance/Accounting Department, andone member of the Information Technology Department. Employees below these departments(shift workers) will be secondary users of the network when they receive information, but theywill not directly use the network.Design Assumptions:This design assumes the following: There is a firewall at the headquarters and each branch to protect all incoming and outgoing projects. All employees will have some sort of PC, VoIP, and printer/fax connected to the network. Internet service is provided by Comcast for the headquarters and the North branch. Charter Communications will be providing for the East branch.Network Design Proposal Page | 3 Yang
    • NETWORK NEEDS ANALYSISData Types:The types of data that will be used across the network are web pages, invoices, andmanagement reports. The majority of the data being transferred will be in text and graphics.Data Sources:Data will be created and used at all end stations of the network The data will beproduced by software applications in Windows Server 2008. Microsoft Office 2010 andQuickBooks Pro 2011 will be used across the organizationfor inputting, creating, and editingdocuments.Number of Users and Priority Levels:At headquarters, the users will be the managers andmembers of the three departments. At the branch level, the users will be the managers andmembers of the two departments. The maximum estimated number of users on the network atany given time is65: 32 users at headquarters, 14 users in the North branch, 14 users in the Eastbranch, and 5 for unanticipated users that could be there to help.Three priority levels will be supported are: management and the three other departments (toppriority), user (medium priority), and external users (low priority). Management and the threeother departments will have access to important data on the server. The medium and low prioritycorrespondents will not have the privilege to retrieve information off the server.Transmission Speed Requirements:The network will require speeds to sustain everydaycomputing and when they continue to expand their business. The average data transfer speed ona 100 Mbps Ethernet is usually around 92 Mbps throughout each LAN. The average downloadspeeds for VoIP is 3.11 Mbps and upload speeds of 3.13 Mbps. This should provide enoughbandwidth for transferring documents and utilizing VoIP across the network.Load Variation Estimates:Most of the hourly average and peak loads occurred duringSeptember through January. The data showed that the average hourly usage was from 7:00 a.m.to 4:30 p.m. The peak usage hours per day was between 10:00 a.m. and noon. Nights andweekend usages were averaging at a minimal, excluding when the computers were being backedup on the network to remote locations.Storage Requirements:The required storage needs to be large enough to store all data. Thisincludes documents from management and invoices. Based on interviews and observations, eachuser will need an average of 500 MB of server space, in addition to secondary storage. Takingprice issues into account, each PC will have a minimum storage of 8 GB. Each LAN server willhave a minimum storage capacity of 16 GB. The network operating system will occupy 500 MBon each LAN server. The main data server at headquarters will have a 32 GB capacity.Network Design Proposal Page | 4 Yang
    • Reliability Requirements:In keeping with user expectations and industry standards, both theLANs and the WAN are expected to operate at 99% uptime and an undiscovered error rate of1%.Security Requirements:A firewall will be used so unauthorized users will be restricted. Part ofthe security will be User accounts and passwords that will give limited access. Managers andusers will have different access capabilities all in which will be given their own username andpassword.Existing Network:There is no existing network.Network Design Proposal Page | 5 Yang
