During the WG meeting today we looked at the following set of questions
posed by implementors. Could people in the working group please look at
these questions and see if they are able to help with answers?
Questions relayed by gorry to the list:
a) Should reported X_recv be used as-is?
b) Should application run the values through "smoothing" function
before using new value?
e.g. using a standard EWMA filter?
c) Calculation of average loss interval in TFRC-SP: the most recent loss
interval is used in calculation only if it's "long" (e.g. >= 2 RTT
is this sufficient for senders not validating X_recv against reported
loss intervals and dropped packets?
d) CCID4 Feedback: options: Are the Loss Intervals / Dropped Packets:
fields too big for Lossless Length, Loss Length, and Data Length?
The lossy part of Loss Interval cannot be > RTT: 24-bit counters appear
to be over-dimensioned especially with CCID-4 (which sends at most 100pps).
e) Due to feedback once per RTT [RFC4828]: Lossless Length and Data
Length fields might also be shorter, e.g. 16 bit or even less?
