Wrap Protection

24

• Relies on a disjoint working and a disjoint protect path between two nodes

• Provides 1:1 protection (only one active LSP) in revertive mode

• Protection switching can be triggered by• Detected defect condition (LDI/AIS,

LKR)

• Administrative action (lockout)

• Far end request (lockout)

• Server layer defect indication (LOS)

• Revertive timer (wait-to-restore)

• No Change to Traffic Flow across the Network

• Compared to MPLS-TE FRR Link/Node Protection

• Sub 50msec Protection for any number of LSPs

• Single Detection and Rewrite Event !

• Everything signaled by the Control Plane, no operational Overhead

Bandwidth Accounting

• Global View/Function

• Make sure that PW Bandwidth is available in the Network

• Steer Traffic (LSPs) to/away from certain Links

• Design “controlled” Oversubscription
