Title: Network load of X terminals at CDF

As an aid to planning future usage of X terminals, the authors measured the network bandwidth used by X terminals on a single Ethernet in a typical application environment at Fermilab. The objectives were twofold. The first objective was to identify the impact of adding one more X terminal onto the CDF Ethernet . The second objective was to determine the maximum number of X terminals allowable on the CDF network. The findings reveal that an X terminal in this environment used, on average, 431 + /{minus}45 bytes/second. This is quite small compared to the utilizable bandwidth of the thinwire Ethernet network (375 Kilobytes/second, equivalent to 30% of total bandwidth). This amounts to an averaged load of .034% on the network per X terminal. This paper addresses the network load solely. It does not address the loads imposed by X terminals on the memory and CPU of the host systems.
