	Title		: A Strawman Architecture for Diffserv Control Plane Elements

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.
