ABSTRACT:
The present invention provides a method and system for the restoration of an optical mesh network subsequent to the simultaneous failing of a large number of network connections due to a transmission failure. The system and method increase the restoration speed of a large number of failed network connections through connection aggregation. The system and method provide that connection aggregation is the logical bundling of a plurality of network connections across a network span. By enabling the bundling of these individual network connections transported over a particular span or spans, a network operator manages the bundle as if it were one network connection. The method and system provide that other network links support these bundled connections when the network segment that a managed bundle is traversing fails.
