Group Assignment - Computer Lab Network Proposal - DRAFT
Content
Introduction
Male’ Business School is a young but fast growing education institute in Maldives providing range of Diploma and Higher Diploma level courses. Since its establishment MBS has given a high priority to improve student resources and experience by innovative IT solutions. Male’ Business School requires installing a Fast Ethernet network between 20 computers of Lab-2. Since Certificate Level 4 and Advance Degree in IT students use the same lab to conduct their sessions, a network is very important between them to share resources and to obtain reference material over the Internet. It has been assigned to the students of ADIT to deploy the network as part of the Assignment for the Networking Concepts module. This document will provide the specifications, including network diagrams, requirement, deployment and testing and a maintenance plan for the proposed network.
Logical Network Diagram
The existing Internet connection will be shared amongst all the PCs. An uplink from the main switch in the office will be connected to the Lab-2 Switch. A logical star topology will be used to connect each PC to the switch. A connection to the NComputing server will be connected from Lab-2 Switch to provide internet connectivity to the library as well. IP addresses will be leased via DHCP from the wireless router, and will be in the Class C range of 192.168.1.0/24. The default gateway and the DNS for all computers will be the IP address of the wireless router (set via DHCP), which will use Network Address Translation (NAT) to forward the requests to the Internet.
Physical Network Diagram
The switch will be placed at the center of the lab as shown in the diagram where the amount cable required will be minimal. Computers will be connected in a physical star topology where a cable from each PC will be connected to the switch. An uplink from office switch will be connected the lab switch via a Cat-6 Cable. A network joint must also be placed to extend the uplink cable up to the lab switch as existing uplink cable is too short. A separate cable need to be laid from the Lab-2 switch to the adjacent room, to give internet connection to the library computers. Additional two cables will be laid to allow for future growth without extra costs or work.
Requirement
Qty 1 50 10 1 1 2 2 1 1 1 Description Rate (MRF) Cat-6 UTP Cable Box (300ft of cable per side) 2,500.00 RJ-45 Cat-6 Ethernet Jacks 5.00 Casing (1” 6ft) 25.00 Silicon Tube 50.00 100Mbps Ethernet Switch 2,500.00 Tools Required Crimping Tool Side Cutter Silicon Gun Network Cable Tester Drill w/ Bit Estimated Total Cost Price (MRF) 2,500.00 250.00 250.00 50.00 2,500.00 5,550.00
Estimated time for the completion of the project is 5 man-hours.
Testing
Cable connectivity will be tested using network cable tester, whether both ends are connected as straight cables. All cables that fail to blink the LEDs for the pairs in sequential order will be need to be examined visually for suspected errors, and re-crimped and re-tested for connectivity via the cable tester. Uplink connectivity can be tested by the issue of DHCP IP addresses via the router. Once an IP is leased (connectivity icon is normal) the computer can be tested for Internet connectivity by browsing the Internet via a web browser. Since the Uplink has a network joint and part of it is old cable, it is recommended to test the bandwidth between Office switch and the Lab-2 switch. A large file will be downloading from a WAMP server connected to the office switch. A throughput of 80% will be considered acceptable.
Maintenance
All the computers must be configured to download the updates during an off-peak time (weekend), and must be checked weekly for viruses and configuration issues. Since all computers are now connected to the Internet, it must be check for download/P2P torrent software running in the background as this might use up the available bandwidth of the Internet.
