Introduction   IANA maintains "OTN Signal Type" subregistry of the "Generalized   Multi-Protocol Label Switching (GMPLS) Signaling Parameters" registry   for OTN signal types (as defined in [RFC4328] and updated by   [RFC7139]).  This subregistry is defined to use only the Standards   Action registration policy as defined by [RFC5226].  This document   updates [RFC7139] to allow the "OTN Signal Type" subregistry to also   use the Specification Required policy as defined in [RFC5226].Ali, et al.                  Standards Track                    [Page 2]RFC 7892           OTN Signal Type Registration Policy          May 20162.  Security Considerations   This document does not introduce any new security considerations to   the existing GMPLS signaling protocols.  Refer to [RFC7139] for   further details of the specific security measures.  Additionally,   [RFC5920] provides an overview of security vulnerabilities and   protection mechanisms for the GMPLS control plane.3.  IANA Considerations   IANA maintains the "OTN Signal Type" subregistry of the "Generalized   Multi-Protocol Label Switching (GMPLS) Signaling Parameters"   registry.  The registry currently is defined to use the Standards   Action registration policy as defined by [RFC5226].   Per this document, IANA has updated the registration policies for the   "OTN Signal Type" subregistry to be "Standards Action" for Standards   Track documents and "Specification Required" for other documents.4.
