Table of Contents

1. Introduction

An earlier specification [RFC7116] defined an IANA registry for administrative record type code points [IANA-BP] for use with the Bundle Protocol (BP) Version 6 (BPv6) [RFC5050]. When Bundle Protocol Version 7 (BPv7) was published in [RFC9171], it identified the IANA registry for administrative record types but did not update the table to be explicit about which entries applied to which Bundle Protocol version(s). The BPv7 specification also did not discriminate between code point reservations and unassigned ranges for administrative record types.¶

This document updates BPv7 to explicitly use the IANA "Bundle Administrative Record Types" registry as described in Section 2. This document makes a reservation of the zero value for consistency with BPv6. This document also makes a reservation of high-valued code points for Private Use and Experimental Use in accordance with [RFC8126] to avoid collisions with assigned code points.¶

2. Administrative Record Types Registry

This document updates the requirements in Section 6.1 of [RFC9171] to specify use of an existing IANA registry and updates that registry as described in Section 4.1.¶

The code point allocated in Annex D of [CCSDS-BP] was never added to the IANA registry. To avoid a collision, this document adds that allocation to the registry.¶

Instead of using the list of types in Section 6.1 of [RFC9171], a BPv7 administrative element SHALL determine which administrative record type code values can be used by the "7" noted in the Bundle Protocol Version column of the IANA "Bundle Administrative Record Types" registry [IANA-BP].¶

If an administrative element receives a not-well-formed application data unit (ADU) or an administrative record type code that is not able to be processed by the element, the record SHALL be ignored by the element. The processing of a received administrative record ADU does not affect the fact that the bundle itself was delivered to the administrative element or any related bundle protocol agent processing of (e.g., status reports on) the enveloping bundle.¶

3. Security Considerations

This document does not define any requirements or structures that introduce new security considerations.¶

The existing security considerations of [RFC9171] still apply when using the IANA "Bundle Administrative Record Types" registry.¶

4. IANA Considerations

This specification modifies a BPv6 registry by extending it for BPv7.¶
