RFC 3048                  RMT Building Blocks               January 2001


   that will be administered by IANA.  Initially, this registry will be
   empty, since the building blocks described in sections 4.1 to 4.3 are
   presented for example and design purposes.  The requested IANA
   building block registry will be populated from specifications as they
   are approved for RFC publication (using the "Specification Required"
   policy as described in RFC 2434 [RFC2434]).  A registration will
   consist of a building block name, a version number, a brief text
   description, a specification RFC number, and a responsible person, to
   which IANA will assign the type number.

7.  Conclusions

   In this document, we briefly described a number of building blocks
   that may be used for the generation of reliable multicast protocols
   to be used in the application space of one-to-many reliable bulk-data
   transfer.  The list of building blocks presented was derived from
   considering the functions that a protocol in this space must perform
   and how these functions should be grouped.  This list is not intended
   to be all-inclusive but instead to act as guide as to which building
   blocks are considered during the standardization process within the
   Reliable Multicast Transport WG.

8.  Acknowledgements

   This document represents an overview of a number of building blocks
   for one to many bulk data transfer that may be ready for
   standardization within the RMT working group.  The ideas presented
   are not those of the authors, rather they are a summarization of many
   years of research into multicast transport combined with the varied
   presentations and discussions in the IRTF Reliable Multicast Research
   Group.  Although they are too numerous to list here, we thank
   everyone who has participated in these discussions for their
   contributions.
