Ethernet
Design Example
As an example, we can examine a network design that is being planned for a group of Computer-Aided Design (CAD) engineers in a large architectural firm. These CAD designers want to replace their existing shared Ethernet LAN with a network that provides greater throughput between their end stations. The Network Designer, who is already familiar with Ethernet networking, does not wish to change the technology that the group uses, and has decided that a simple and cost-effective way to provide more bandwidth to each end station is through per-port switched Ethernet connections.
The CAD department consists of 16 CAD designers, 2 CAD image file servers, and 3 plotters, all in a single facility. The stations have existing 10BASE-T links to the wiring closet. The CAD department is currently linked to the rest of the company through an Ethernet connection to a bridge in the Materials Research department. The Network Designer, hoping to simplify the network, wants to connect the CAD group directly to the corporate backbone, an FDDI ring.
