Layer 2 circuit—A
method of transporting Layer 2 frames between provider edge (PE) routers
across an MPLS backbone using LDP signaling.
circuit cross-connect (CCC)—A Juniper Networks method of exchanging frames between one
router interface running a Layer 2 protocol and another router interface
using the same Layer 2 protocol. For more information about CCC, see
either the JUNOS Network Interfaces Configuration Guide or the JUNOS MPLS Applications
Configuration Guide.
control word—A
32-bit field used in Layer 2 circuits to transport sequence information,
Layer 2 media control information, and padding.
