Re: [aqm] Document Action: 'The FlowQueue-CoDel Packet Scheduler and Active Queue Management Algorithm' to Experimental RFC (draft-ietf-aqm-fq-codel-06.txt)

[Megan Ferguson <[e-mail]>]

Mirja,

Thank you for sending these updates along.  We have noted these changes in the database and they will be 
reviewable once the document reaches AUTH48.  

Please let us know if we can be of further assistance.
