To meet these concerns a network upgrade will occur in two phases. 100baseFX cabling will be run from the Ethernet switch to a switch in each network closet. Errors will not propagate throughout a subnet. The dedicated wiring will reduce the chance of user induced problems. A software package called VLAN will manage subnet switching and distribution thereby saving labor costs.
Dedicated wiring enables port control for security purposes.
In the event of a security breach, administrators can disable ports without affecting other equipment. Improved ATM backbone. Since software routines not have to find the beginning and ending of each cell, transmission time decreases. ATM's Quality of Service guarantees also help eliminate jitter often associated with video or voice applications running over an Ethernet network. As of this time the rewiring of the building is approximately half completed.
