are the same size as iperf's . This will be addressed in a better way
in the future.

Fixed initialization bug in the bandwidth-measurement argument code. Fixed a bug where throughputTick was getting called too often. Added more data for DELAY_DETAIL logging. Removed Nagle's algorithm from the control traffic on the stub side. Added a new bandwidth option. Now there are three. Changed the naming scheme to be more specific (it was too generic before).

according to the input option: -m <method>. Currently when <method> =
"base" the goodput measurement using the whole packet size will be used;
when no -m is given, the optimized method drawn from TCP vegas will be
used by default.

Fixed a time-calculation bug in the monitor. Added bandwidth and base-rtt calculations based on TCP-vegas. Miscellaneous cleanups.

Fixed a transient error discovered by Junxing. Rather, I've fixed a bug that could account for it and the error hasn't resurfaced after many runs. The transient symptom was when pcap only captured the first three packets and failed from then on.

All measurement times are now based on packet timestamps rather than gettimeofday(), throughput measurement is much more consistent now, though a more thorough evaluation is still required.

Delay is averaged over a quantum. This is probably not the right thing to do, but it is better than the alternative (latest measurement). I am still discussion with Sneha about what to do here.

Added standalone support for multiple streams. Added a logging infrastructure. Added a trivial application for testing purposes (dumb-client and dumb-server). Added the capability for running the standalone stub with a tcpdump replay. Added support for changing buffer sizes. Added shell files for experiment management, reset.sh which is to reset the dummynet settings between runs and run-iperf.sh which encapsulates a set of options to iperf.

Fixed several minor bugs in Rob's scripts. Added the capability for multiple streams along the same path to the monitor/stub loop. Replaced the linear searches with logarithmic searches. Cleaned up various associated parts of the code.

TODO: Finish connection recycling capability
TODO: Remove commented out older code after more debugging

reporting does not start until the first quanta in which  traffic is
recieved, and exits when the number of bytes in a quanta goes back
down to zero.

Also change quanta to 500ms, as suggested by Jon.

mode, or the db entry gets marked as invalid.

Fixed an overflow bug in the pcap code. Added a timer to make throughput more accurate (this still needs tweaking and isn't quite right).

Expanded monitor to be more generic (not bound to a particular IP address ,etc.). Added throughput measurement to the stub (note that the throughput measurements are not sent to the monitor, only printed to the screen). Added the first primitive traffic modeling to the stub. Changed the stub defines to agree with the monitor (monitor port == 4200).
