Ethernet Load (Server Load):
Ethernet Load can be called also server load. It is presented as a number which values start from 0.00. This procedure represent the number of processes that queuing for getting permission to access the processor(s), which are measured in certain period of time.If a large number of processes occur at the same time the response time is consequently much higher (Lemnaru, 2010).
Increasing of a network can have an impact on the server load and Ethernet delay, but this is not the case in some circumstances. The expansion of the network also affects the server load and Ethernet delay. In the Initial simulation (first-floor), carried for this report, consisted 30 workstations which were used over a time period of 30 minutes. Afterwards other 2 groups of workstations, each consisted of 15 workstations, was added. On Figure 5 the first floor scenario (red line), the expansion scenario (blue line) and second floor (green line) are presented.
The expansion scenario is higher than first floor scenario. This tendency was expected, as an result of an increase of workstations in the expansion which caused a delay in the Ethernet load. The first floor, second floor and expansion scenario start rising from the same point (0 bits/sec). However, expansion and second floor scenarios reach higher level than first floor scenario, because they have a longer load delay than the first floor. Nevertheless, after reaching the highest pick amplitudes of all 3 scenarios tend to level off towards the end, to denote a stable network.

Figure 5 Server or Ethernet Loads(bits/sec)
According to the result that appeared in Figure 5; in the first floor scenario the amount of the load that caused by thirty hosts is approximately 6,000bits/sec. The expansion scenario with fifteen hosts added server load is to nearly 8,850bits/sec. For the second floor reaches the
