Data description: The original data and description of the file formats from Felix is available [ here  ].

Each trace is really in two files. A large file provides, for each packet, the packet time, flow number and number of bytes. A small file describes each flow, providing details like the flow number, source&destination IP addresses and ports, and some other information.

Breakdown: A breakdown summary of the data (e.g. number of packets & flows, number of packets per protocol type) is available [ here ].
 

Semi-experiment 1 - Flow start times moved to Poisson time points.
1) Calculate the sample mean of the interarrival times for flow starts.
2) Create a new sequence of interarrival times as the jump times of  a Poisson process. The mean interarrival time for the jumps of the Poisson process is set to be the sample mean of the true interarrival times.
3) Shift the beginning of the nth arriving flow to the nth calculated Poisson time point.

All packet files have the  same 3 column format: 1 line for each packet with packet time, flow number, bytes in packet.
(For simplicity I have subtracted 988,000,000.000000 from all packet times in the original trace to keep them more manageable. )
