Title : BGP Extended Community Attribute for QoS Marking

This document specifies a simple signalling mechanism for inter-
domain QoS marking using a BGP Extended Community QoS Attribute.
Class based packet forwarding for delay and loss critical services is
currently performed in an individual AS internal manner. The new QoS
marking attribute makes the QoS class setup within the IP prefix
advertising AS known to all access and transit ASes. This enables
individual (re-)marking and forwarding treatment adaptation to the
original QoS class setup of the respective IP prefix. The attribute
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.Requirements Language
