- Abstract
- Provided is a multi-layer restoration method using a LCAS (Link Capacity Adjustment Scheme) in a synchronous network having a mesh structure. The method includes: performing a hardware restoration method if a network failure is detected; performing a pre-planned restoration method if the network failure is not repaired by performing the hardware restoration method; determining whether channels that pass along a line where the network failure occurs use the LCAS if the network failure is not repaired by performing the pre-planned restoration method; and applying the LCAS to the channels if the channels are determined to use the LCAS, and performing a dynamic restoration method if the channels are not determined to use the LCAS. The multiplayer restoration method minimizes data loss due to an increase in restoration time and overcomes service disconnection caused by failure to obtain a spare channel.
