For an evaluation of the traffic we performed several mea-
surements capturing the Ethernet traffic at the Office Com-
munication server. The capturing of the traffic was performed
using the popular Wireshark tool [7], which reports complete
Ethernet frame sizes, including the Ethernet overhead per
captured frame of 14 bytes. We initially dropped frames that
do not adhere to standard (with sizes greater than 1514 bytes,
as the network did not allow Jumbo frames) and aggregated the
remaining captured frames on a per-second basis to determine
the bandwidth. Specifically, we aggregate the size of all Ether-
net frames within a specific second from the beginning of the
measurement and denote the resulting bandwidth as Xt [bps].
We denote the average bandwidth as X [bps] and Xmax [bps]
as the maximum bandwidth observed. Subsequently, we denote
the Peak-to-Mean ratio (as one measure for the variability of
the underlying traffic) of the bandwidth defined as P tMX .
2We calculate the variance SX and standard deviation SX of
the observed bandwidth usages to calculate the coefficient of
variation, commonly used to measure the variability of an
underlying variable, and denote it as CoVX .
