 IANA Registries for the Remote Direct Data Placement (RDDP) Protocols

Abstract

   The original RFCs that specified the Remote Direct Data Placement
   (RDDP) protocol suite did not create IANA registries for RDDP error
   codes, operation codes, and function codes.  Extensions to the RDDP
   protocols now require these registries to be created.  This memo
   creates the RDDP registries, populates them with values defined in
   the original RDDP RFCs, and provides guidance to IANA for future
   assignment of code points within these registries.

1.  Introduction

   The original RFCs that specified the RDDP protocol suite [RFC5040]
   [RFC5041] [RFC5043] [RFC5044] did not create IANA registries.
   Extensions to the RDDP protocols [RFC6581] [RMP-EXT] now require
   creation and use of IANA registries.  This memo creates the RDDP-
   related IANA registries, specifies their initial contents based on
   the values defined in the original RDDP RFCs, and provides guidance
   to IANA for future assignments from these registries.  In addition,
   this memo allocates operation code and function code points for
   experimental use [RFC3692].

2.  Security Considerations

   Since this document is only concerned with creation and IANA
   management of RDDP registries, it raises no new security issues.

   However, a few words are necessary about the use of the experimental
   code points defined in Sections 3.4 and 3.5.  Potentially harmful
   side effects from the use of the experimental values need to be
   carefully evaluated before deploying any experiment across networks
   that the owner of the experiment does not entirely control.  Guidance
   given in [RFC3692] about the use of experimental values needs to be
   followed.

3.  IANA Considerations

   Allocation requests for the registries created by this memo may come
   with a suggested numerical value or values that should be assigned.
   Such suggestions are useful when early implementations have already
   chosen particular code points before the final RFC is published.  If
   the allocation request in general is accepted, such suggestions may
   be honored if the suggested value is still free to be assigned.
