  DESCRIPTION
    "Copyright (C) The IETF Trust (2007).  This version of
     this MIB module is part of RFC 4801; see the RFC itself for
     full legal notices.

     This MIB module defines TEXTUAL-CONVENTIONs for concepts used in
     Generalized Multiprotocol Label Switching (GMPLS) networks."

GmplsFreeformLabelTC ::= TEXTUAL-CONVENTION
  STATUS      current
  DESCRIPTION
    "This TEXTUAL-CONVENTION can be used as the syntax of an object
     that contains any GMPLS Label.  Objects with this syntax can be
     used to represent labels that have label types that are not
     defined in any RFCs.  The freeform GMPLS Label may also be used
     by systems that do not wish to represent labels that have
     label types defined in RFCs using type-specific syntaxes."

GmplsLabelTypeTC ::= TEXTUAL-CONVENTION
  STATUS      current
  DESCRIPTION
    "Determines the interpretation that should be applied to an
     object that encodes a label.  The possible types are:

     gmplsMplsLabel(1)           - The label is an MPLS Packet, Cell,
                                   or Frame Label and is encoded as
                                   described for the TEXTUAL-
                                   CONVENTION MplsLabel defined in
                                   RFC 3811.

     gmplsPortWavelengthLabel(2) - The label is a Port or Wavelength
                                   Label as defined in RFC 3471.

     gmplsFreeformLabel(3)       - The label is any form of label
                                   encoded as an OCTET STRING using
                                   the TEXTUAL-CONVENTION
                                   GmplsFreeformLabel.

     gmplsSonetLabel(4)          - The label is a Synchronous Optical
                                   Network (SONET) Label as
                                   defined in RFC 4606.

     gmplsSdhLabel(5)            - The label is a Synchronous Digital
                                   Hierarchy (SDH) Label as defined
                                   in RFC 4606.

     gmplsWavebandLabel(6)       - The label is a Waveband Label as
                                   defined in RFC 3471."

GmplsSegmentDirectionTC ::= TEXTUAL-CONVENTION
  STATUS      current
  DESCRIPTION
    "The direction of data flow on an Label Switched Path (LSP)
     segment with respect to the head of the LSP.

     Where an LSP is signaled using a conventional signaling
     protocol, the 'head' of the LSP is the source of the signaling
     (also known as the ingress) and the 'tail' is the destination
     (also known as the egress).  For unidirectional LSPs, this
     usually matches the direction of flow of data.

     For manually configured unidirectional LSPs, the direction of
     the LSP segment matches the direction of flow of data.  For
     manually configured bidirectional LSPs, an arbitrary decision
     must be made about which LER is the 'head'."
  SYNTAX  INTEGER {
    forward(1),   -- data flows from head-end of LSP toward tail-end
    reverse(2)    -- data flows from tail-end of LSP toward head-end
  }
