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.

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. 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
• 192-255: Private or experimental use. No assignment by IANA.

The Value range is: unsigned 8 bit integer.

Bundle Block Type Codes Registry

The value "0" was not defined in any document or in the adhoc registry. As per concensus by the DNTRG research group, it is reserved per this document.

3.2. Primary Bundle Protocol Version

The Bundle Protocol has a version field (section 4.5.1) [RFC5050]. An IANA registry shall be setup as follows.

The registration policy for this registry is: RFC Required

The Value range is: unsigned 8 bit integer.

Primary Bundle Protocol Version Registry

The value "0-5" was not defined in any document or in the adhoc registry. As per concensus by the DNTRG research group, it is reserved per this document.

3.3. Bundle Processing Control Flags

The Bundle Protocol has a Bundle Processing Control flags field (section 4.2) [RFC5050] encoded as an SDNV(see section [sdnv]). An IANA registry shall be setup as follows.

The registration policy for this registry is: Specification Required

The Value range is: Variable length. Maximum number of flag bit positions: 64

Bundle Processing Control Flags Registry

3.4. Block Processing Control Flags

The Bundle Protocol has a Block Processing Control flags field (section 4.3) [RFC5050]. An IANA registry shall be setup as follows.

The registration policy for this registry is: Specification Required

The Value range is: Variable length. Maximum number of flag bit positions: 64

Block Processing Control Flags Registry

3.5. Bundle Status Report Flags

The Bundle Protocol has a Status Report Status Flag field(section 6.1.1) [RFC5050]. An IANA registry shall be setup as follows.

The registration policy for this registry is: RFC Required

The Value range is: 8 bits.

Bundle Status Report Flags Registry

The value "00000000" was not defined in any document or in the adhoc registry. As per concensus by the DNTRG research group, it is reserved per this document.

3.6. Bundle Status Report Reason Codes

The Bundle Protocol has a Bundle Status Report Reason Codes field(section 6.1.1) [RFC5050]. An IANA registry shall be setup as follows.

The registration policy for this registry is: Specification Required

The Value range is: unsigned 8 bit integer.

Bundle Status Report Reason Codes Registry

The value "255" was not defined in any document or in the adhoc registry. As per concensus by the DNTRG research group, it is reserved per this document.

3.7. Bundle Custody Signal Reason Codes

The Bundle Protocol has a Bundle Custody Signal Reason Codes field(section 6.1.2) [RFC5050]. An IANA registry shall be setup as follows.

The registration policy for this registry is: Specification Required

The Value range is: unsigned 7 bit integer.

Bundle Custody Signal Reason Codes Registry

The value "127" was not defined in any document or in the adhoc registry. As per concensus by the DNTRG research group, it is reserved per this document.

4. Security Considerations

This document requests the creation of registries managed by IANA. There is no security issues involved. Refer to Security Considerations of the referenced protocols.

5. IANA Considerations

IANA is requested to create the registries as described in the previous sections.
