General RBUDP & TCP Conclusions
From the combined RBUDP and TCP
bandwidth results, presented in the
"Bandwidth Interval
Plots" and
"Data Size Plots"
sections, the following conclusions can be drawn:
-
Besides the statement from the developers that
RBUDP is not TCP friendly, there
still has been considerable adjustment from the
RBUDP flow to the TCP flows,
especially when the # TCP flows and / or the shaping bandwidth is
increasing.
-
Probably due to the almost zero round-trip time there are no differences
between the situations where the
RBUDP flow is delayed (left
plots) and where the multiple TCP flows are delayed (right plots).
-
When five parallel flows between node pairs have been used instead of one,
but with the constraint that the sum of the shaping bandwidth over the
parallel flows is the same in both situations, the adjustment of the
RBUDP flow to the TCP flows is
much larger in the situation with five parallel flows.
-
When the RBUDP data size has
been enlarged the adjustment from the
RBUDP flow to the TCP flows is
decreasing.
