Delay-Tolerant Networks (DTN) Bundle Protocol IANA Registries
draft-irtf-dtnrg-iana-bp-registries-02.txt
Abstract
The DTNRG research group has defined many protocols such as Bundle
Protocol and Licklider. The specifications of these protocols
contain fields that are subject to a registry. For the purpose of
its research work, the group created adhoc registries. As the
specifications are stable and have multiple interoperable
implementations, the group would like to handoff the registries to
IANA for official custody. This document describes the actions
needed to be executed by IANA.

Internet-Draft DTN IANA Registries February 2011
1. Introduction
The DTNRG research group has defined many protocols[RFC4838] such as
Bundle Protocol[RFC5050] and Licklider[RFC5326]. The specifications
of these protocols contain fields that are subject to a registry.
For the purpose of its research work, the group created adhoc
registries [1]. As the specifications are stable and have multiple
interoperable implementations, the group would like to handoff the
registries to IANA for official custody. This document describes the
actions needed to be executed by IANA.
2. Treatment of Flag Fields Encoded using SDNVs
The DTN protocols use several extensible bit flag fields that are
encoded as Self-Delimiting Numeric Values (SDNVs) as defined in
Section 4.1 of [RFC5050]. For these fields, the registry specifies
the allocation and usage of bit positions within the unencoded field.
The SDNV encoding treats the ensemble of bits in the unencoded value
as a numeric value to be encoded on transmission and decoded on
reception as described in [RFC5050].
Processing of SDNV-encoded flags is discussed in
[I-D.irtf-dtnrg-sdnv].
Section 4.1 of [RFC5050] specifies that implementations are not
required to handle SDNVs with more than 64 bits in their unencoded
value. Accordingly SDNV encoded flag fields should be limited to 64
bit positions.
IANA Registry policies and wording used in this document are
described in [RFC5226].
3. Bundle Protocol
The Bundle Protocol(BP)[RFC5050] has fields requiring a registry
managed by IANA.
3.1. Bundle Block Types
The Bundle Protocol has a Bundle Block Type code field (section
4.5.2) [RFC5050]. An IANA registry shall be setup as follows.
The registration policy for this registry is:
0-191: Specification Required
Blanchet Expires August 29, 2011 [Page 3]
