GMPLS Interfaces
The GMPLS architecture extends MPLS to include five different types of interfaces used on label switch routers:
Packet-switch capable (PSC) interfaces— Interfaces that can recognize packet boundaries and forward data based on packet headers. This is typical of interfaces on routers and L3 Ethernet switches.
Layer 2–switch capable (L2SC) interfaces— Interfaces that can recognize L2 cell or frame boundaries and forward data based on L2 headers. This is typical of interfaces on ATM switches, Frame Relay switches, and L2 Ethernet switches.
Time-division multiplexing (TDM) interfaces— Interfaces that can recognize time slots and forward data based on the data's time slot in a repeating cycle. This is typical of interfaces on digital ...
