      protocol and above, protocols that apply to the whole Internet;
      and (2) network-specific protocols, generally specifications of
      how to do IP on particular types of networks.

   5.1.2.  Draft Standard Protocol

      The IAB is actively considering this protocol as a possible
      Standard Protocol.  Substantial and widespread testing and comment
      is desired.  Comments and test results should be submitted to the
      IAB.  There is a possibility that changes will be made in a Draft
      Standard Protocol before it becomes a Standard Protocol.

   5.1.3.  Proposed Protocol

      These are protocol proposals that may be considered by the IAB for
      standardization in the future.  Implementation and testing by
      several groups is desirable.  Revisions of the protocol
      specification are likely.

   5.1.4.  Experimental Protocol

      A system should not implement an experimental protocol unless it
      is participating in the experiment and has coordinated its use of
      the protocol with the developer of the protocol.

      Typically, experimental protocols are those that are developed as
      part of a specific ongoing research project not related to an
      operational service offering.  While they may be proposed as a
      service protocol at a later stage, and thus become proposed,
      draft, and then standard protocols, the designation of a protocol
      as experimental is meant to suggest that the protocol, although
      perhaps mature, is not intended for operational use.

   5.1.5.  Historic Protocol

      These are protocols that are unlikely to ever become standards in
      the Internet either because they have been superseded by later
      developments or due to lack of interest.  These are protocols that
      are at an evolutionary dead end.

5.2.  Definitions of Protocol Status

   5.2.1.  Required Protocol

      All systems must implement the required protocols.

   5.2.2.  Recommended Protocol

      All systems should implement the recommended protocols.

   5.2.3.  Elective Protocol

      A system may or may not implement an elective protocol. The
      general notion is that if you are going to do something like this,
      you must do exactly this.

   5.2.4.  Not Recommended Protocol

      These protocols are not recommended for general use.  This may be
      because of their limited functionality, specialized nature, or

Note:  It is expected that a system will support one or more physical
networks and for each physical network supported the appropriate
protocols from the above list must be supported.  That is, it is
elective to support any particular type of physical network, and for the
physical networks actually supported it is required that they be
supported exactly according to the protocols in the above list.

The Internet Activities Board has designated two different network
management protocols with the same status of "Draft Standard" and
"Recommended".  The two protocols are the Common Management Information
Services and Protocol over TCP/IP (CMOT) [RFC-1095] and the Simple
Network Management Protocol (SNMP) [RFC-1098].  The IAB intends each of
these two protocols to receive the attention of implementers and
experimenters.  The IAB seeks reports of experience with these two
protocols from system builders and users.  By this action, the IAB
recommends that all IP and TCP implementations be network manageable
(e.g., implement the Internet MIB [RFC-1066], and that implementations
that are network manageable are expected to adopt and implement at least
one of these two Internet Draft Standards.  The motivation for this
position is discussed in RFCs 1052 and 1109.
