                 Generalized SCSI: A Generic Structure
          for Interface Switching Capability Descriptor (ISCD)
            Switching Capability Specific Information (SCSI)

Abstract

   This document defines a generic information structure for information
   carried in routing protocol Interface Switching Capability Descriptor
   (ISCD) Switching Capability Specific Information (SCSI) fields.  This
   "Generalized SCSI" can be used with routing protocols that define
   GMPLS ISCDs and any specific technology.  This document does not
   modify any existing technology-specific formats and is defined for
   use in conjunction with new GMPLS Switching Capability types.  The
   context for this document is Generalized MPLS, and the reader is
   expected to be familiar with the GMPLS architecture and associated
   protocol standards.

1.  Introduction

   The context for this document is Generalized MPLS, and the reader is
   expected to be familiar with the GMPLS architecture, associated
   terminology, and protocol standards: notably, but not limited to,
   [RFC3945], [RFC4202], [RFC4203] and [RFC5307].

   The Interface Switching Capability Descriptor (ISCD) [RFC4202] allows
   routing protocols such as OSPF and ISIS to carry technology-specific
   information in the Switching Capability-specific information field,
   see [RFC4203] and [RFC5307].  The format of an SCSI field is dictated
   by the specific technology being represented as indicated by the ISCD
   Switching Capability field.  Existing Switching Capabilities are
   managed by IANA in the "Switching Types" registry
   <http://www.iana.org/assignments/gmpls-sig-parameters> and the
   related "IANA-GMPLS-TC-MIB" definitions.

   [RFC7138] introduced a "sub-TLV" structure to its technology-specific
   SCSI field.  The sub-TLV-based approach allows for greater
   flexibility in the structure, ordering, and ability to support
   extensions of the SC-specific format.  This Sub-TLV approach is also
