These are results from GENI-Tmix experiments run on two ProtoGENI nodes for one hour each with Iperf flows.

These experiments consisted of 1 Iperf flow (or 10 Iperf flows) starting at time t=0, and then the GENI-Tmix emulation was started at time t=10min. That emulation consisted of 156,131 TCP connections, each connection emulating the minimum Round Trip Time (RTT) that was measured in the original production link.

Time Series of Throughput in the two directions for the two hour long experiments

One Iperf flow starts at time t=0, the Tmix emulation starts at time t=10min; compare this to the Tmix-only emulation below

Tmix aggregate - Average throughput: 14Mbps and 6Mbps; compare this with the Tmix aggregate with no Iperf - Average throughput: 15Mbps and 7Mbps

Iperf flow - Average throughput: 84Mbps and 2Mbps

The time series of throughput in Mbps is shown in both directions for the single Iperf flow as well as the aggregated Tmix emulation.

Note how the single Iperf flow has affected the TCP connections in the Tmix emulation and vice versa.

Time Series of Throughput in the two directions shown for the 10 Iperf flows as well as the aggregated throughput for Tmix emulation

Tmix aggregate - Average throughput: 11Mbps and 4.5Mbps

Iperf flow - Average throughput: each of the 10 Iperf flows averaged ~ 8.8 Mbps in the above experiment

2Mbps for all 10 Iperf flows in dir-1to2

Note: The ten Iperf flows start at the same time t=0, the Tmix emulation starts at time t=10min

The time series of throughput in Mbps is shown in both directions for the 10 Iperf flows separately (identifying them by port) as well as the aggregated Tmix emulation.
