[Csci551-talk] Re: [Cs551] question-logging

[Michael Stephens]

I am sorry, I do not mean to be monopolizing the discussion board, but
now I am really confused.

Affan's message says to log the message when it is actually sent, not
when it is queued.

Xi's email seems to imply that the message should be logged when it is
queued (i.e. when the client "thinks" it is sent).

Which one is it?  (Or have I misinterpreted one or both postings?)

Thank you everyone for your continuing help...Michael

When to start timeout
Sorry for the delayed response but it was a good question and needed
some thought. 
The correct approach has got to be to start timer as soon as you buffer
the packet. But the log time should be when it is actually sent. I know
this can create pathological scenarios, but this is most realistic and
we can test your implementation through simpler scenarios :)

Thanks.

Again and again, bandwidth limitation is seperate component to simulate 
underlying network (Internet) behavior. So the rest of your program 
don't know when the packets are received. The conclusion is log a 
message as soon as you send it.
