Hi,

We updated the I-D's Abstract to clarify the problem, and our proposal for an incentive that may encourage video endpoints to generate more discardable packets in lower drop precedence within AF PHB groups in DiffServ. Thanks for your comments in advance.

Best regards,
CJ

Abstract:
   In DiffServ, preferential dropping of packets in AF PHB groups has
   long been considered beneficial, typically for video flows with
   discardable packets.  Unfortunately, the ecosystem of bandwidth
   contention at congestion is very likely to discourage those video
   endpoints from generating packets with lower precedence markings,
   i.e. they would lose more packets if doing so.  Thus, to offer an
   incentive for more collaborative and mutually beneficial behaviors of
   video endpoints in AF PHB groups, we propose a Normalization Marker
   (NM) for traffic conditioning at network edges.  Deployment of NM
   will encourage the video endpoints to generate finer layers of intra-
   flow precedence (IFP) with discardable packets in more balanced
   distributions.
