Shaped Bandwidth Plots

In the following sub-sections results are displayed in the form of UDT and multiple TCP bandwidth plots as a function of the sum of the shaped TCP bandwidth taken over the Iperf thread flows. The bandwidth values are presented with average values that are calculated in the areas with only UDT, only TCP, and with combined UDT & TCP traffic types. These flows are generated in the same way as described before in the "Description" subsection. In each plot the following plot traces are presented, entitled:

UDT (Only)
Contains the UDT bandwidth results in the area with only this type of traffic.
UDT (& Iperf)
Contains the UDT bandwidth results in the area where the UDT & TCP traffic types are combined.
Sum Iperf (Only)
Contains the sum over the TCP Iperf flows in the area with only this type of traffic.
Sum Iperf (& UDT)
Contains the sum over the TCP Iperf flows in the area with combined UDT &TCP traffic types.

In the plots of the average bandwidth values from the UDT and / or TCP traffic types listed above are presented as a function of the shaped Iperf bandwidth using one threaded parallel flow per node pair. The figures are displaying the results of tests from 1 × 1 to 11 × 11 node pairs as usual grouped into two VLAN's where each node is sending a TCP flow to all other participating nodes in the opposite VLAN.
