<abstract>
<t>
   This document defines an architecture for implementing scalable
   service differentiation in the Internet.  This architecture achieves
   scalability by aggregating traffic classification state which is
   conveyed by means of IP-layer packet marking using the DS field
   .  Packets are classified and marked to receive a particular
   per-hop forwarding behavior on nodes along their path.  Sophisticated
   classification, marking, policing, and shaping operations need only
   be implemented at network boundaries or hosts.  Network resources are
   allocated to traffic streams by service provisioning policies which
   govern how traffic is marked and conditioned upon entry to a
   differentiated services-capable network, and how that traffic is
   forwarded within that network.  A wide variety of services can be
   implemented on top of these building blocks.
