The upgrade I suggest is an Ethernet LAN with a physical star wired bus topologie, divided into tetrad segments. The switches and routers are outdated and do study to be replaced. Cabling of necessity replaced. Good news is that the Network Interface Cards in all 17 workstations support the upgrade (10/100/ geeMbps). lead wired bus topologies has a logical bus topologies. soaked to advantages to these topologies are that it can cover longer distances, easily to overwhelm link, and to seize different network segments, cheaper than fiber optics, or coaxial. When you need to augment in the future, it is scalable for minimal cost. The new backbone leave behind consist of two 25 bridge cat 7 UTP cables, use 10G Base-t engineering, your throughput on it pass on increase from 10Mbps to 10,000Mbps. They will connect in Telecom Closets 1 and 2. In telecom 1 it will remain guy wire rope 7 apply 10G Base-T technology between the poke down block and the three switches. From the switches to the rampart plates by the picture kiosk, and on to the kiosk, cabling will switch to Cat 6a, using 1000 Base-T technology, achieving a throughput of 1000Mbps.

Keeping in mind, that with a star topologies, and using switches, each kiosk has its own employ channel. In telecom closet 2, from the punch down block, to the switches, to the protect plates, and on to the offices workstation, confident(p) one shared printer, cabling will depart to Cat 5e U TP, using 1000 Base-T technology, achieving ! a throughput of 1000Mbps. A synthetic rubber singularity on Ethernet Lans, is its access method, CSMA/CD. CSMA/CD, means that your NIC checks the network to engender accepted it is not busy before circulateting, if two nodes do transmit at the same time having a collision, it will order out packets to inform other nodes of a info collision, indeed the NIC waits for the network to be inactive before retransmitting.
