I read the source and I am not very sure about the
QTSSFlowControlModule and RTPBandWidthChecker.
Below my opinion:
QTSSFlowControlModule deal with both UDP and RUDP
protocol. It just tell the loss percent of RTP
pachets(from RTCP packets), and if it is above the
mark, it counts the times and sets the quality of the
playing.Though which, it can thin or thick the given
client's bandwidth.
Well, RTPBandWidthCheck just deals with RUDP
protocol.It saves the client-window size, and keeps
the congestion window's size. It keeps the bytes
already sent and wait for the acks( something
implement TCP protocol) and resize the
window-size(something like sliding window in TCP,
right?).
Give me some advice.

Steven
