| "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 |
| } |
