<abstract>
<t>This document was originally submitted as an internet draft in November of 1997. As one of the documents predating the formation of the IETF's Differentiated Services Working Group, many of the ideas presented here, in concert with Dave Clark's subsequent presentation to the December 1997 meeting of the IETF Integrated Services Working Group, were key to the work which led to RFCs 2474 and 2475 and the section on allocation remains a timely  roposal.
For this reason, and to provide a reference, it is being submitted in its original form. The forwarding path portion of this document is intended as a record of where we were at in late 1997 and not as an indication of future direction.</t>
<t>The postscript version of this document includes Clark's slides as an appendix. The postscript version of this document also includes many figures that aid greatly in its readability.</t></abstract></front>
