Definition of the Differentiated Services Field (DS Field) in the IPv4 and IPv6 Headers
TL;DR: Differentiated services enhancements to the Internet protocol are intended to enable scalable service discrimination in the Internet without the need for per-flow state and signaling at every hop.
An Expedited Forwarding PHB
TL;DR: This document describes a PHB called Expedited Forwarding, noting that it can be produced by more than one mechanism and giving an example of its use to produce at least one service, a Virtual Leased Line.
Definition of Differentiated Services Per Domain Behaviors and Rules for their Specification
Kathleen Nichols,Brian Carpenter +1 more
TL;DR: The differentiated services framework enables quality-of-service provisioning within a network domain by applying rules at the edges to create traffic aggregates and coupling each of these with a specific forwarding path treatment in the domain through use of a codepoint in the IP header as discussed by the authors.

Differentiated services in the Internet
Brian Carpenter,Kathleen Nichols +1 more
TL;DR: This paper takes the position that it is possible to maintain reasonable QoS levels without recourse to any of the class of constrained routing approaches (including MPLS), though Diffserv can be used with these approaches if desired.
Journal ArticleDOI
Controlling Queue Delay: A modern AQM is just one piece of the solution to bufferbloat.
Kathleen Nichols,Van Jacobson +1 more
TL;DR: The "persistently full buffer problem" is still with us and made increasingly critical by two trends: cheap memory and a "more is better" mentality have led to the inflation and proliferation of buffers as discussed by the authors.
