A new Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Diameter Maintenance and Extensions Working Group of the IETF.
Title : Diameter Congestion and Filter Attributes
Author(s) : B. Hirschman, et al
Filename : draft-ietf-dime-congestion-flow-attributes
Pages : 9
Date : 2014-10-29
This document defines optional ECN and filter related attributes that
can be used for improved traffic identification, support of ECN and
minimized filter administration within Diameter.
RFC 5777 defines a Filter-Rule AVP that accommodates extensions for
classification, conditions and actions. It does not support traffic
identification for packets using Explicit Congestion Notification as
defined in RFC 3168 and does not provide specific actions when the
flow(s) described by the Filter-Rule are congested.
A Filter-Rule can describe multiple flows but not the exact number of
flows. Flow count and other associated data (e.g. packets) is not
captured in Accounting applications, leaving administrators without
useful information regarding the effectiveness or understanding of
the filter definition.
These optional attributes are forward and backwards compatible with
RFC 5777.
