MULTI-LAYER NETWORK PROTECTION METHOD AND APPARATUS

摘要

Disclosed are a fault recovery method in a multi-layer network and an apparatus thereof. According to an embodiment of the present invention, the fault recovery method comprises the steps of: acquiring setting information of a lower layer backup path through a signaling message which is used to set a label-based path; setting the lower layer backup path on the basis of the obtained setting information of the lower layer backup path; and performing protection switching via the lower layer backup path set when a fault is detected in the lower layer.
