Write up Current State of Network Architecture and connections The current network architecture of Huffman Trucking s network is very outdated Currently there are four geographical locations and two individual networks at each location one office network and one plant network These networks are all configured differently with different equipment and very little consistency in architecture between each network All the office networks connect to the Internet but since California holds the web server there is no firewall Both Missouri and Ohio plants have connections through a fractional T1 but California has a standard AOL model connection dial up The wiring infrastructure is consistent across the networks but is rated at Cat3 There is also no clear voice network California runs off a standard PBX whereas Missouri and Ohio both have Avaya digital switches The computers in the company range from Windows 31 boxes to Windows XP What needs to be changed and why One of the most important characteristics of a good IT infrastructure is consistency Most of the computers need to be the same the servers need to be the same throughout the network and the voice equipment needs to be consistent The first thing that needs to change is all computers need to be running Windows XP with the exception of the Macs The technology of Windows 31 and Windows 98 is to antiquated for today s technology Having all Windows boxes with XP will help ensure easy manageability data surety and when problems do arise XP can be supported and repaired The next change arises from the physical infrastructure of the networks Cat 3 is old and slow the equipment made for it isn t manufactured anymore therefore finding support for any of this equipment will be hard to find and expensive Connections between locations and to the internet need to be consistent Using AOL and modems at one location while having a T1 at others doesn t give a very efficient operations ow The networks all seem to operate independently so if one site goes down nothing is lost unless you are at that site but what about communications and load balancing between the sites during normal working hours Proposed Architecture and Topology for the network Team D is proposing a total reorganization of Huffman Trucking s Network Architecture based on the reasons stated above This new network will have scalability integrity and easier manageability It will also have to the ability to load balance between sites if one or multiple sites go down The topology itself will be a star topology This will help with troubleshooting the locations of problems while at the same time not crashing the network The network itself will be a Windows Domain network Servers At each geographical location there will be a cluster of 3 servers with 6 servers at the main headquarters The Satellite clusters will have 3 main functions One server will act as a secondary Domain Name ServerDNS the second server will be a local file storage and printing server The third server will act as a fall overbackup for the other two The main server cluster located at Headquarters will have one Server as the primary DNS the second server will be a Citrix server for sales the board accounting and any other employees that need to be able to work from home but VPN is insufficient to the task The third will be the main applications and data server This server will hold the files and folders used by all departments in the company The satellite server used for local storage will have information pertaining to the files and folders used by the satellite locations but the main data server will be the central repository where backups and source files and folders are stored This will allow personnel from all over the company to acess needed files and folders irrespective of geography The fourth will be a mail server using Exchange 2003 Standard This will allow up to 67 Gig worth of total email space across the company If the size reaches more than the 67 Gig limit Huffman will have to upgrade to enterprise The fifth server will be a back up server connected to a tape drive Backups will be able to be done in full incremental and decremental schemes The sixth and final server will be a load balancing server for the clusters This will allow traffic to continue between sites if one or two sites go down Internet and infrastructure The infrastructure Will need to be taken out and all Wire runs rerun With Cat 6 gigabit The network itself Will not immediately need gigabit speeds it Will run at 100 mbps but in the future the need will arise for Cat 6 doing this now Will ensure that the cost of future upgrading is some What diffused Internet for the company Will consist of a main internet portal at the headquarters through Which all satellites Will have a managed VPN line into headquarters
