Title : BGP Extended Community for QoS Marking
Author(s) : T. Knoll
Filename : draft-knoll-idr-qos-attribute-04.txt
Pages : 18
Date : 2009-07-09
This document specifies a simple signalling mechanism for inter-
domain QoS marking using several instances of a new BGP Extended
Community. Class based packet marking and forwarding is currently
performed independently within ASes. The new QoS marking community
makes the targeted Per Hop Behaviour within the IP prefix advertising
AS and the currently applied marking at the interconnection point
known to all access and transit ASes. This enables individual
(re-)marking and possibly forwarding treatment adaptation to the
original QoS class setup of the respective originating AS. The
extended community provides the means to signal QoS markings on
different layers, which are linked together in QoS Class Sets. It
provides inter-domain and cross-layer insight into the QoS class
mapping of the source AS with minimal signalling traffic.
