Abstract
Multi-layer transport network consisting of several layers provides a protection mechanism for recovery actions for survival of the transport network. The upper layer path occupies the resource of the rest of the normal link including the lower layer fault link in order to return to the path. We propose a resource management for multi-layer transport networks, to a scheme for registering a normal link resource assigned to a path in which a fault occurs, as a reusable resource. The normal link will use the low-priority traffic transmission resource and it can be to improve the resource utilization of multi-layer transport network. We also present the multi-layer resource management and path control system for the proposed scheme.
