Abstract:
This memo describes a Normalization Marker (NM) at DiffServ (DS)
nodes to normalize the distribution of DS codepoint (DSCP) markings
for an Assured Forwarding (AF) Per-Hop Behavior (PHB) group. NM is
useful for traffic conditioning with Active Queue Management (AQM)
when the AF PHB group is deployed for multimedia service classes that
carry video packets with advanced codec technologies. Using NM can
offer an incentive that is however missing in today's ecosystem of
practical deployment, i.e., when congestion occurs in the AF PHB
group, the network should allow a video codec to benefit from its
effort of generating finer layers of intra-flow precedence (IFP) with
discardable packets in a more balanced distribution.
