GMPLS Technology
GMPLS supports five types of interfaces:
- PSC - Packet Switching Capable: IP/MPLS
- L2SC - Layer-2 Switching Capable: ATM, FR, Ethernet
- TDM - Time-Division Multiplexing: Sonet, SDH, G.709 ODU
- LSC - Wavelength Switching: Lambda, G.709 OCh
- FSC - Fiber Switching
GMPLS extends MPLS/MPLS-TE control plane
- LSP establishment spanning PSC or L2SC interfaces is defined in MPLS/MPLS-TE control planes
- GMPLS extends these control planes to support this five classes of interfaces (i.e. layers)
As MPLS-TE, GMPLS provides
- separation b/w transmission, control and management plane
- network management using SNMP (dedicated MIB)
