Abstract:
This document defines optional Diameter attributes that can be used
to help manage networks that use Explicit Congestion Notification
(ECN) or Diameter traffic filters. These new attributes allow for
improved data traffic identification, support of ECN and minimize
Diameter filter administration.
RFC 5777 defines a Filter-Rule Attribute Value Pair (AVP) that
accommodates extensions for classification, conditions and actions.
It however, 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.
Further, a Filter-Rule can describe multiple flows but not the exact
number of flows. Flow count and other associated data (e.g. packets)
are not captured by Accounting applications, leaving administrators
without useful information regarding the effectiveness or
appropriateness of the filter definition.
The optional attributes defined in this document are forward and
backwards compatible with RFC 5777.
