	Title		: Using Self-Delimiting Numeric Values in Protocols

Self-Delimiting Numeric Values (SDNVs) have recently been introduced
   as fields used in proposed Delay-Tolerant Networking protocols.  The
   basic goal of an SDNV is to hold a non-negative integer value of
   arbitrary magnitude, without consuming much more space than
   necessary.  The primary motivation is to conserve the bits sent
   across low-capacity or energy-intensive links typical of NASA deep-
   space missions, with a secondary goal of allowing the protocol to
   automatically adjust to unforseen usage scenarios.  This can be
   desirable in that it allows protocol designers to avoid making
   difficult and potentially erroneous engineering decisions that may
   have to be hacked around in the future.  This document describes
   formats and algorithms for SDNV encoding and decoding, and discusses
   implementation and usage of SDNVs.

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.

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