Set B 50msec Packet InterArrival 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 50msec packet interarrival time for Set B.
In Figures 38 to 41, the mean time stamp is far enough from zero to show the symmetric pattern produced by the time stamp outliers.
Figure 38: Automatic 10Mbit/sec Figure 39: Explicit 10Mbit/sec Figure 40: Automatic 100Mbit/sec Figure 41: Explicit 100Mbit/sec
Tables 33 to 36 show that the mean values are still close to the theoretical values of 50083usec for 10Mbit/sec and 50008.3usec for 100Mbit/sec while the variance and standard deviation are very large.
Table 33: Automatic 10Mbit/sec (usec)
Mean Varience Standard Deviation 50083.72 200894.80 448.21
Table 34: Explicit 10Mbit/sec (usec)
Mean Varience Standard Deviation 50083.74 198314.20 445.32
Table 35: Automatic 100Mbit/sec (usec)
Mean Varience Standard Deviation 50008.82 209105.20 457.28
Table 36: Explicit 100Mbit/sec (usec)
Mean Varience Standard Deviation 50008.83 186779.70 432.18
