Abstract

Self-Delimiting Numeric Values (SDNVs) have recently been introducedas 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 provideprotocol flexibility without sacrificing economy and to assist infuture-proofing protocols under development. This document describesformats and algorithms for SDNV encoding and decoding, along withnotes on implementation and usage. This document is a product of theDelay-Tolerant Networking Research Group and has been reviewed bythat group. No objections to its publication as an RFC were raised. This document is not an Internet Standards Track specification; it ispublished for informational purposes.
