Hi Ma,
We use the term "window" loosely here, to stand for "all the packets
sent in a round trip time". That paragraph is describing a
hypothetical system that we did not in fact implement so it is not
worth worrying about the definitions.

Dear Friends,
While reading the paper "Designing DCCP: Congestion Control Without
Reliability", I was confused by CCID2.
In page 7, section 4.2, paragraph 4, line 6~7.
It says: "If the sender did not hear from the receiver that all of
the packets in a window of data were received,
..... "
What does the term "packets of a window of data" means?
Does it means the sequence of packets that are sent out every time
" int(cwnd_) - pipe_ > 0"?
Say if current cwnd_ == 4.35, and pipe_ == 3, "packets of a window
of data" is acctually 1 packet. Am I right?
So, in order to tell whether two lost packet is in the same window
or not, the sender has to keep some
"packet seqno <-> window seqno" mappping in mind after sending out
the packets?
Please kindly let me know the error if above statement is problemetic.
Thank you very much!
