A Revised Internet-Draft is available from the on-line Internet-Drafts 
directories. This draft is a work item of the Integrated Services Working 
Group of the IETF.

This memo describes the network element behavior required to deliver 
Controlled Delay service in the Internet.  Controlled delay service 
provides three levels of delay control; network elements, when overloaded, 
are required to control delay by denying service requests.  However, there 
are no quantitative assurances about the absolute level of delay provided. 
The controlled delay service is designed for service-adaptive and 
delay-adaptive applications; i.e., applications that are prepared to 
dynamically adapt to changing packet transmission delays and to dynamically
change the level of packet delivery delay control they request from the 
network when their current level of service is not adequate.  The 
controlled delay service imposes relatively minimal requirements on network
components that implement it, and is intended to be usable in situations 
ranging from small centrally managed private IP networks to the global 
Internet.  This specification follows the service specification template 
described in [1].

Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-ietf-intserv-control-del-svc-02.txt".
							
NOTE: The mail server at ds.internic.net 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.
							
For questions, please mail to [e-mail].
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
