Management Plane to Control Plane Handover Operation Management Plane Control Plane MP to CP handover signaling Data Plane Client A Client B Data plane circuit connecting clients A and B is in place and it is under control of NMS MP transfers circuit related information to CP entity at circuit’s Ingress TNE Ingress TNE formats such info into a standard GRSVP-TE setup messaging, including all details allowing for a precise description of the LSP to be created at CP level (ERO and US/DS label). GRSVP-TE signalling targeted at MP to CP handover is a standard PATH/RESV/RESV CONFIRM LSP setup flow, where a flag in ADMINISTRATIVE STATUS is set TNEs involved in A-B circuit process the handover signaling, creating LSP records within CP, but not taking any action over data plane, where the actual connections stay untouched Ingress TNE Egress TNE Detailed (timeslot level) circuit description data |
