MPLS AToM Virtual CircuitConnection Verification ( VCCV)
Draft-ietf-pwe3-vccv-xx.txtIETF StandardsIETF Standards
Layer 2 transport over MPLS
FRoMPLS, ATMoMPLS, EoMPLSApplicationsApplications
AToM VCCV allows sending control packets in band of an AToMpseudowire. Two components:
Signaled component to communicate VCCV capabilities as part
of VC label
Switching component to cause the AToM VC payload to be treated as acontrol packet
Type 1: uses Protocol ID of AToM Control word
Type 2: use MPLS router alert label
SolutionSolution
Ability to provide end-to-end fault detection and diagnostics for anemulated pseudowire service
One tunnel can serve many pseudowires.
MPLS LSP ping is sufficient to monitor the PSN tunnel (PE-PEconnectivity), but not VCs inside of tunnel
