 AB - Prepare presentation for meeting with Suman.
+PK - Actually early 04/25. Started from scratch last night. Finished a new server - even added graphing GUI. Architected class hierarchy and implemented round robin scheduler (since it does not require any actual capture or analysis) as a means of exercising the class hierarchy. I like it so far. Very pleased. This screen grab shows the server receiving from a SuperTcpClient with 2 (simulated) adapters with the round robin scheduler. The graph is the last 60 seconds. The dip is the current second.

+==== 04/25 ====
+PK - Decided to take a chance to write super-TCP. Came up with plan. Spent 24 hours straight on it. Concluded it is too big for this late in the semester.
+==== 04/27 ====
+PK - AB - several hour meeting came up with concrete plan for finishing this project.
+PK - started over again.
+==== 04/28 ====
+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 - AB - meet for an hour for code review, status.
+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.
