       Title     : The Use of SNTP as a Multicast Heartbeat

This document describes how the Simple Network Time Protocol (SNTP) can be 
used to provide a multicast heartbeat. Given the current state of the art 
in multicast diagnostics, use of a heartbeat may prove a useful diagnostic 
tool for operators as well as for applications developers.   Operators may 
use the heartbeat to alert themselves to losses of multicast connectivity 
in portions of the network.  Applications developers may use the heartbeat 
to determine whether to enable multicast features or to default to unicast 
operation.  While it is likely that better diagnostic methods will become 
available in the long term,  given the current state of the art, SNTP may 
be usefully employed as a multicast hearbeat.

Send a message to:  mailserv@ds.internic.net. In the body type: 
     "FILE /internet-drafts/draft-ietf-mboned-sntp-heart-01.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.



Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
