Subject: Clarifications regarding assn 3

(This message is being sent to all CPSC 360 students)

A student who is systematically taking the proper
detail oriented approach asks in regard to the following
sample output:

rps_connect  mgc  = 2b1a, seq = 0, ack = 0, len = 0, flg = 1, win = 16
sig=ca1b0b00
rps_connect  ack = 0 snd = 0 in = 0 out = 0 itms = 0 slts = 16 owin = 0


>> What does win mean?

This is a good question that I should have better clarified
in class.

The variable win is the number of free buffers in the receive
ring but for the connect protocol its irrelevant and a value of
0 is fine.

The second line is produced by "dump_sender_state()" a very
important function for tracking data transfer. The values
printed there are

  nxtack
  nxtsnd
  sndring.nextin
  sndring.nexout
  sndring.items
  sndring.slots
  offwin

But these are also NOT APPLICABLE to the present assignment
and so printing them is fine but not necessary.
