<p>The present invention discloses a recovering method in a complex optical transport network. The method comprises the steps of: predetermining a standby route information for each network element in the optical transport network by a background system; transmitting said standby route information of each network element to the associated network elements by said background system; detecting the operation condition of the network in real time and updating said standby route information in real time by said background system; detecting associated change within the network in real time and performing operation related to the standby route based on the change by said network elements. The invention can carry out dynamic recovery of traffic in the complex optical transport network, and enable the network to have a multi-failures recovering ability.</p> |
