            Using Self-Delimiting Numeric Values in Protocols


   Self-Delimiting Numeric Values (SDNVs) have recently been introduced    as a field type in proposed Delay-Tolerant Networking protocols.    SDNVs encode an arbitrary-length non-negative integer or arbitrary-    length bitstring with minimum overhead.  They are intended to provide    protocol flexibility without sacrificing economy and to assist in    future-proofing protocols under development.  This document describes    formats and algorithms for SDNV encoding and decoding, along with    notes on implementation and usage.  This document is a product of the    Delay-Tolerant Networking Research Group and has been reviewed by    that group.  No objections to its publication as an RFC were raised.
