Abstract
Protection Bundles (PB) facilitate efficient protection switching in a network and can be applied at any network layer. A PB is preferably assigned to all working signals sharing the exact same protection facilities. The working facilities that a PB traverses define a Bundled Protection Fragment (BPF)(560, 564, 568). The end-points of the BPF exchange coordination protocol messages along the protection facilities when necessary. The protection facilities between the end-points of a BPF define each BPFs Common Protection Route (CPR)(562, 566, 570).
