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.
