These trace files represent the time-varying capacity of U.S. cellular
|
|
networks as experienced by a mobile user. They were recorded using the
|
|
"Saturator" tool described in the research paper:
|
|
|
|
K. Winstein, A. Sivaraman, and H. Balakrishnan, "Stochastic Forecasts
|
|
Achieve High Throughput and Low Delay over Cellular Networks", USENIX
|
|
NSDI 2013, https://www.usenix.org/conference/nsdi13/technical-sessions/presentation/winstein

Each line gives a timestamp in milliseconds (from the beginning of the
|
|
trace) and represents an opportunity for one 1500-byte packet to be
|
|
drained from the bottleneck queue and cross the link. If more than one
|
|
MTU-sized packet can be transmitted in a particular millisecond, the
|
|
same timestamp is repeated on multiple lines.
|
|
|
|
A fixed-rate link may also be represented a trace file. For example, a
|
|
link that can pass one MTU-sized packet per millisecond (12 Mbps) can
|
|
be represented by a file that contains just "1". By default, mm-link
|
|
will repeat the trace file when it reaches the end, so this trace
|
|
would represent one packet per millisecond.
