The University has recently leased a building in Adelphi, Maryland to house offices, classrooms, library, and computer labs. The goal of this proposal is to design a network for these facilities. The Student computers are to be on a separate network from the staff computers. The facility will share one Internet connection (T-1 link from Verizon). With a T-1 link the network will be able to function with the speed of 1.544 mbps over 24 channels each running 64 kbps (Labsim). Security is always a big concern and has been taken into consideration. Additional considerations for each floor/classroom/lab/office include printing capabilities and the WiFi (Wireless Access) in the Student Lobby. The network design …show more content…
When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is 100 meters or 328 feet, so using the Cat 6 cabling will allow for some extra feet for going around walls and into ceilings to be able to reach the various rooms (Wikipedia, 2014). Also using STP Cat-6 or shielded twisted pair cabling features more stringent specifications for crosstalk and system noise usually created by EMI or electromagnetic interference (XMultiple). The Cat6 STP will also physically be wired as a star topology where each computer node is wired with its own Ethernet cable to the centralized switch.
Estimating the cable length needed has many variables; actual measurement of the rooms, available space in either the floors or ceilings, how the computers and devices will be placed in the room, etc. I have made an estimate allowing for extra cable in case of possible repair and other circumstances. The chart below are my estimates of the room sizes on the two floors.
