Abstract :
The ability of local area networks (LANs) to handle the large amount of data transfer among distributed workstations is frequently questioned. A LAN study is reported which investigated both the Ethernet LAN and the Distributed HP-UX data communication protocol implemented on it. An approach involving experimentation and analytical and simulation modeling was followed. The models were vigorously validated against each other and the measurements. The performance study of the DUX/LAN system concentrated on investigating the causes of the message transit time and its variability. According to this study, the message communication time is dominated by transmission delays and not LAN contention, and the LAN performs well in the 30-50% channel utilization range
