0.  Document Background

   {{{ RFC Editor: Please delete this section prior to publication. }}}

   This document is a split off from draft-iab-iana-framework-02.  This
   document contains principles that were scattered in various places in
   the IANA Framework, pulling them into one place.

   The IANA Framework has been under discussion since February 2011.

1.  Introduction

   The Internet Engineering Task Force (IETF) and its predecessors have
   traditionally separated the publication of protocol specifications in
   immutable Request for Comments (RFCs) and the registries containing
   protocol parameters.  The latter is maintained by a set of functions
   traditionally known collectively as the Internet Assigned Numbers
   Authority (IANA).  Dating back to the earliest days of the Internet,
   specification publication and the registry operations were tightly
   coupled: Jon Postel of the Information Sciences Institute (ISI) of
   the University of Southern California (USC) was responsible for both
   RFC publication and IANA registry operation.  This tight coupling had
   advantages, but it was never a requirement.  Indeed, today the RFC
   Editor and IANA registry operation are provided by different
   entities.

   Internet registries are critical to the operation of the Internet,
   since they provide a definitive record of the value and meaning of
   identifiers that protocols use when communicating with each other.
   Almost every Internet protocol makes use of registries in some form.
   At the time of writing, the IANA maintains more than two thousand
   protocol parameter registries.

   Internet registries hold protocol identifiers consisting of constants
   and other well-known values used by Internet protocols.  These values
   can be numbers, strings, addresses, and so on.  They are uniquely
   assigned for one particular purpose or use.  Identifiers can be
   maintained in a central list (such as a list of cryptographic
   algorithms) or they can be hierarchically allocated and assigned by
   separate entities at different points in the hierarchy (such as IP

   addresses and domain names).

   The registry system is built on trust and mutual cooperation.  The
   use of the registries is voluntary and is not enforced by mandates or
   certification policies.  While the use of registries is voluntary, it
   is noted that the success of the Internet creates enormous pressure
   to use Internet protocols and the registries associated with them.

   This document provides principles for the operation of IANA
   registries, ensuring that protocol identifiers have consistent
   meanings and interpretations across all implementations and
   deployments, and thus providing the necessary trust in the
   registries.

2.  Principles for the Operation of IANA Registries

   The following key principles underscore the successful functioning of
   the IANA registries, and they provide a foundation for trust in those
   registries:

   Ensure Uniqueness:  The same protocol identifier must not be used for
      more than one purpose.

   Stable:  Protocol identifier assignment must be lasting.

   Predictable:  The process for making assignments must not include
      unexpected steps.

   Public:  The protocol identifiers must be made available in a manner
      that makes them freely available to everyone in well-known
      locations.

   Open:  The process that sets the policy for protocol identifier
      assignment and registration must be open to all interested
      parties.

   Transparent:  The protocol registries and their associated policies
      should be developed in a transparent manner.

   Accountable:  Registry policy development and registry operations
      need to be accountable to the affected community.

3.  Discussion

   The principles discussed in Section 2 provide trust and confidence in
   the IANA registries.

Internet-Draft          IANA Registry Principles           December 2014


3.1.  Ensuring Uniqueness, Stability, and Predictability

   Protocol identifier assignment and registration must be unique,
   stable, and predictable.  Developers, vendors, customers, and users
   depend on the registries for unique protocol identifiers that are
   assigned in a stable and predictable manner.

   A protocol identifier may only be reassigned for a different purpose
   after due consideration of the impact of such a reassignment, and if
   possible, with the consent of the original assignee.

   Recognizing that some assignments involve judgment, usually by a
   designated expert [RFC5226], a predictable process does not mean that
   it will complete in a predetermined number of days.  Rather, it means
   that no unexpected steps are introduced in the process of making an
   assignment.

3.2.  Public

   Once assigned, the protocol identifiers must be made available in a
   manner that makes them freely available to everyone without
   restrictions.  The use of a consistent publication location builds
   confidence in the registry.  This does not mean that the publication
   location can never change, but it does mean that it must change
   infrequently and only after adequate prior notice.

3.3.  Open and Transparent

   The process that sets the policy for protocol identifier assignment
   and registration must be open to all interested parties and operate
   in a transparent manner.

   When a registries is established, a policy is set for the addition of
   new entries and the updating of existing entries.  While making
   additions and modifications, the registry operator may expose
   instances where policies lack of clarity.  When this occurs, the
   registry operator should provide helpful feedback to allow those
   policies to be improved.  In addition, the registry operator not
   being involved in establishing registry policy avoids the risks
   associated with (perceptions of) favoritism and unfairness.

   Recognizing that some assignments involve judgment, usually by a
   designated expert [RFC5226], the recommendations by such experts must
   be visible to the public and open to challenge.

3.4.  Accountable

   The process that sets the policy for protocol identifiers and the
   operation of the registries must be accountable to the parties that
   rely on the protocol identifiers.  Oversight is needed to ensure
   these are properly serving the affected community.

   In practice accountability mechanisms for the registry operator may
   be defined by contract, memoranda of understanding, or service level
   agreements (SLAs).  An oversight body uses these mechanisms to ensure
   that these registry operator is meeting the needs of the affected
   community, but the oversight body is held accountable to the affected
   community by vastly different mechanisms, for instance recall and
   appeal processes.

   For protocol parameters [RFC6220], the general oversight over the
   IANA function is performed by the IAB as a chartered responsibility
   from [RFC2850].  In addition the IETF Administrative Oversight
   Committee (IAOC), a body responsible for IETF administrative and
   financial matters [BCP101], maintains an SLA with the current
   registry operator, the Internet Corporation for Assigned names and
   Numbers (ICANN), thereby specifying the operational requirements with
   respect to the coordination, maintenance, and publication of the
   protocol parameter registries. Both the IAB and the IAOC are
   accountable to the larger Internet community and are being held
   accountable through the IETF Nomcom process [BCP10].

4.  Security Considerations

   Internet Registries are critical to elements of Internet security.
   The principles described in this document are necessary for the
   Internet community to place trust in the IANA registries.
