Thank you for your liaison "Update on FSA signalling draft
Recommendation Q.Flowstatesig," posted June, 2011. In response to
your request for comments on the Q.flowstatesig draft recommendation,
we have conducted an open IETF review of the draft recommendation,
which lasted from June 8, 2011 to July 5, 2011.
The open IETF review and other internal reviews evaluated the text of
"Signalling protocols and procedures relating to Flow State Aware QoS
control in a bounded sub-network of a NGN" as published in your
liaison of June, 2011 and available at
The conclusion of those reviews is that it is not likely that the
deployment of the specified protocols and procedures would have a
negative impact on the operation of the Internet where those protocols
and procedures are not deployed.
