Abstract -
The performance assessment of a networkcan becentered on fixed parameters like throughput and delay and others. The technology performancesdeal withauser’s number or nodes in addition toconfirmed generation parameters. Thepurposes of this workis toestimate and explore the performances ofthroughput concentrated on traffic received,downloaded objects and pages as well as delay& loadbased on most basic technologies: Ethernet besides FDDI. By simulating two scenarios, first one contain 10 nodes with the other of 20 nodes. The effect of numerous network configurations on created scenarios were examined with a network simulator OPNET. The concluded diagrams ofthe Ethernet throughput be greater than at FDDIdue to their abilities for filtering errorsand to avoid collisions,while FDDI load anddelay which experienced atthese networkscan be consideredless than Ethernetifan equalnodes number could be utilized.At last, the effect of the downloaded objects and pages for Ethernet network with10 & 20 nodes are explained and proves as greater than that for 10 &20 nodes for FDDI networks.
