Differentiated Services (DiffServ)
From the IETF's Differentiated Services (DiffServ) Work Group's site:
The differentiated services approach to providing quality
of service in networks employs a small, well-defined set of building
blocks from which a variety of aggregate behaviors may be built. A
small bit-pattern in each packet, in the IPv4 TOS octet or the IPv6
Traffic Class octet, is used to mark a packet to receive a particular
forwarding treatment, or per-hop behavior, at each network node.
Examples of DiffServ-based services include the Premium IP
and "Less-than Best Effort" (LBE)
services available on GEANT/GN2 and some NRENs.
