Title:
RECOVERING METHOD IN A COMPLEX OPTICAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2006/058458
Kind Code:
A1
Abstract:
The present invention relates to a recovering method in a complex optical network. The method comprises the steps of: pre-determining a standby route information for each net element in the optical network by a background system; transmitting said standby route information of each net element to the associated net elements by said background system; detecting the operation condition of the network in real time by said back ground system; updating said standby route information in real time; detecting the change within the network in real time by said net elements; and performing the operation related to the standby route based on the change. The invention can carry out dynamic recovering of traffic in the complex optical network, and enable the network to have a multi-failures recovering ability.
