Evolution of a Standard
MPLS: MultiProtocol Label Switching
- IP packet based
- Packet Traffic Engineering (MPLS-TE)
MPlS: MultiProtocol Lambda Switching
- MPLS control applied on optical channels (wavelengths/lambda’s) and IGP TE extensions
GMPLS: Generalized MPLS
- MPLS control applied on circuits (SDH/Sonet) and optical channel layer and IGP TE extensions
- New Protocol introduction: LMP
GMPLS: “separation” b/w Technology dependent and independent
- LMP extended to “passive devices” via LMP-WDM
- GMPLS covers G.707 SDH, G.709 OTN…
