Hi TCPM,

We were experimenting with TCP code in a VM setting.
We reduced the minimum RTO, because average RTT should be much lower than 1 second.
We got lots of spurious retransmissions in a heavily loaded host.
As a result, we developed an alternative to the exponential weighted moving average
algorithm to determine the RTO. It operates well without any minimum RTO setting.

Please take a look and comment.

A new version of I-D, draft-heitzhe-tcpm-vm-rto-00.txt has been successfully submitted by Jakob Heitz and posted to the IETF repository.

Name:		draft-heitzhe-tcpm-vm-rto

Title:		TCP Retransmission Timer for Virtual Machines

Abstract:
   A Round Trip Time (RTT) estimate that decays performs badly in a
   bursty environment. A round trip time estimator that does not decay
   for a period of time is proposed.

   It does not require a minimum value to be configured. It works
   equally well when the typical RTT is 100uS as when it is 10 seconds.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
