Set B 1msec Packet Inter-Arrival Time
The following section discusses the difference between automatically allowing the interface to detect the line speed and explicitly setting the line speed of an interface for 1msec packet inter-arrival time for Set B.
As seen in Figures 34 to 37, the three-tier effect also occurs when the packet inter-arrival time is set to 1msec. Since negative time is impossible, the patterns do not appear symmetrical about the mean.

Tables 29 to 32 again show that for all configurations of the line speed (both auto-detect and static) the varience and standard deviation are very large.
Table 29: Automatic 10Mbit/sec (usec)
Mean Varience Standard Deviation 1083.21 54052.28 232.49
Table 30: explicit 10Mbit/sec (usec)
Mean Varience Standard Deviation 1083.21 54195.47 232.80
Table 31: Automatic 100Mbit/sec (usec)
Mean Varience Standard Deviation 1008.33 50107.46 223.85
Table 32: Explicit 100Mbit/sec (usec)
Mean Varience Standard Deviation 1008.33 49048.92 221.47
