Hi all,

we have now updated the draft to address the outstanding comments. The 
main changes from last version are:

   o  Changed the algorithm to allow RTOR when there is unsent data 
available, but the cwnd does not allow transmission.
   o  Changed the algorithm to not trigger if "RTO - T_earliest" <= 0, 
to avoid that ACKs to previous retransmissions trigger premature 
timeouts.
   o  Made minor adjustments throughout the document to adjust for the 
algorithmic changes.
   o  Improved the wording throughout the document.


for experimental results and a Linux implementation, please visit:

Cheers,
Per
