GENI-Tmix experiments on ProtoGENI
nodes
In this set of experiments we illustrate how Tmix can be used to generate realistic network traffic. We
used a fraction of the network traffic captured on the production link
connecting a large university campus to its ISPs.
Traffic
captured on a Campus Production Link
471 Mbps (average throughput) in
one direction,
and 202 Mbps in the opposite direction;
4.7 million connections
carrying 290 GB of application data
We used the Tmix traffic
generation system to emulate about 1/30 of the above traffic on two ProtoGENI nodes. This input traffic used for the
experiments in ProtoGENI consisted of 156,131 TCP
connections over an hour-long experiment.
We ran several such experiments. Three sample
experiments are shown here (Tmix
emulation only) and here (Tmix
emulation with 1 Iperf flow and Tmix
emulation with 10 Iperf flow). Those links
contain details and the results of those experiments.
