Concluded it is too big for this late in the semester. But will continue thinking about it as developing a framework for this future work would make a nice addition to the project's report. |

| PK - experimented with blocking and non-blocking socket member. With non-blocking I crashed my computer every time when I hammered the adapter but did not do this with blocking set. Flag must do something :). Later this day: First fully functioning version of new client / server. | PK - experimented with blocking and non-blocking socket member.

| PK - a few more hours in. I added three more transmission "models" to the client: load,burst and random. I have replaced the processor based clock and am now using DateTime.Now.Ticks to make the code portable to Linux. This means same-machine/same-subnet RTTs are 0. I added the adapter cumulative loss/ooo counts. I added timestamps in acks. Have conclusive evidence that the blocking socket flag does nothing in UDP. Forced to put in Thread.SpinWait every N bulk transmissions so that we don't spill so many segments on the floor, even before they've hit the wire. | PK - a few more hours in.
