Title : A Strawman Architecture for Diffserv Control Plane Elements
Author(s) : K. Nichols, et al.

Diffserv (RFC 2474, 2475, and 3086) made explicit that
IP QoS can be separated into the differentiated
treatment given to packets in the forwarding path and
the task of configuring these forwarding path
components to allocate QoS according to policy and
availability. The IETF Diffserv WG described the
forwarding path architecture in detail and specified
some specific forwarding path elements. This draft
attempts a similar approach of specifying the elements
of a diffserv control plane, gives a general
architecture and example solution that fits into this
architecture, and lays out some issues. An example of a
diffserv control plane architecture is presented,
derived from the control plane described in RFC2638,
and an example implementation of that approach is
briefly described. The authors hope to stimulate a
discussion of the architectural model and its elements
and to elicit more example solutions that may fit,
change, or extend the model.
A control plane must be configurable, secure, and
monitorable. The authors believe the operations and
management issues of a diffserv control plane must be
made explicit and the approach to solving them properly
constrained. Resolving operational and management
issues is key to moving to availability of IP QoS.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
