RFC2474 - Definition of the Differentiated Services Field (DS Field) in the IPv4 and IPv6 Headers: This document defines the IP header field, called the DS (for differentiated services) field. [STANDARDS-TRACK]
RFC2475 - An Architecture for Differentiated Services: This document defines an architecture for implementing scalable service differentiation in the Internet. This memo provides information for the Internet community.
RFC2597 - Assured Forwarding PHB Group: This document defines a general use Differentiated Services (DS) Per-Hop-Behavior (PHB) Group called Assured Forwarding (AF). [STANDARDS-TRACK]
RFC2598 - An Expedited Forwarding PHB: The definition of PHBs (per-hop forwarding behaviors) is a critical part of the work of the Diffserv Working Group. This document describes a PHB called Expedited Forwarding. [STANDARDS-TRACK]
RFC2836 - Per Hop Behavior Identification Codes: This document defines a binary encoding to uniquely identify PHBs (Per Hop Behaviors) and/or sets of PHBs in protocol messages. [STANDARDS-TRACK]
RFC2983 - Differentiated Services and Tunnels: This document considers the interaction of Differentiated Services (diffserv) with IP tunnels of various forms. This memo provides information for the Internet community.
RFC3086 - Definition of Differentiated Services Per Domain Behaviors and Rules for their Specification: This document defines and discusses Per-Domain Behaviors in detail and lays out the format and required content for contributions to the Diffserv WG on PDBs and the procedure that will be applied for individual PDB specifications to advance as WG products. This format is specified to expedite working group review of PDB submissions. This memo provides information for the Internet community.
RFC3140 - Per Hop Behavior Identification Codes: This document defines a 16 bit encoding mechanism for the identification of differentiated services Per Hop Behaviors in protocol messages. It replaces RFC 2836. [STANDARDS-TRACK]
RFC3246 - An Expedited Forwarding PHB (Per-Hop Behavior): This document defines a PHB (per-hop behavior) called Expedited Forwarding (EF). The PHB is a basic building block in the Differentiated Services architecture. EF is intended to provide a building block for low delay, low jitter and low loss services by ensuring that the EF aggregate is served at a certain configured rate. This document obsoletes RFC 2598. [STANDARDS-TRACK]
RFC3247 - Supplemental Information for the New Definition of the EF PHB (Expedited Forwarding Per-Hop Behavior): This document was written during the process of clarification of RFC2598 "An Expedited Forwarding PHB" that led to the publication of revised specification of EF "An Expedited Forwarding PHB". Its primary motivation is providing additional explanation to the revised EF definition and its properties. The document also provides additional implementation examples and gives some guidance for computation of the numerical parameters of the new definition for several well known schedulers and router architectures. This memo provides information for the Internet community.
RFC3248 - A Delay Bound alternative revision of RFC 2598: For historical interest, this document captures the EF Design Team's proposed solution, preferred by the original authors of RFC 2598 but not adopted by the working group in December 2000. The original definition of EF was based on comparison of forwarding on an unloaded network. This experimental Delay Bound (DB) PHB requires a bound on the delay of packets due to other traffic in the network. At the Pittsburgh IETF meeting in August 2000, the Differentiated Services working group faced serious questions regarding RFC 2598 - the group's standards track definition of the Expedited Forwarding (EF) Per Hop Behavior (PHB). An 'EF Design Team' volunteered to develop a re-expression of RFC 2598, bearing in mind the issues raised in the DiffServ group. At the San Diego IETF meeting in December 2000 the DiffServ working group decided to pursue an alternative re-expression of the EF PHB. This memo provides information for the Internet community.
RFC3260 - New Terminology and Clarifications for Diffserv: This memo captures Diffserv working group agreements concerning new and improved terminology, and provides minor technical clarifications. It is intended to update RFC 2474, RFC 2475 and RFC 2597. When RFCs 2474 and 2597 advance on the standards track, and RFC 2475 is updated, it is intended that the revisions in this memo will be incorporated, and that this memo will be obsoleted by the new RFCs. This memo provides information for the Internet community.
RFC3289 - Management Information Base for the Differentiated Services Architecture: This memo describes an SMIv2 (Structure of Management Information version 2) MIB for a device implementing the Differentiated Services Architecture. It may be used both for monitoring and configuration of a router or switch capable of Differentiated Services functionality. [STANDARDS-TRACK]
RFC3290 - An Informal Management Model for Diffserv Routers: This document proposes an informal management model of Differentiated Services (Diffserv) routers for use in their management and configuration. This model defines functional datapath elements (e.g., classifiers, meters, actions, marking, absolute dropping, counting, multiplexing), algorithmic droppers, queues and schedulers. It describes possible configuration parameters for these elements and how they might be interconnected to realize the range of traffic conditioning and per-hop behavior (PHB) functionalities described in the Diffserv Architecture. This memo provides information for the Internet community.
RFC3317 - Differentiated Services Quality of Service Policy Information Base
