Method and system for restoring and recovering traffic in multi-layer communication networks after two or more failures and virtual controller device

The method in order to recover said traffic from a second failure uses at least one virtual controller device for establishing, for a selected pair of upper layer nodes of a network, an alternative path through a lower layer of said network for conducting traffic, and for deleting selected paths thr...

More Information
Summary:The method in order to recover said traffic from a second failure uses at least one virtual controller device for establishing, for a selected pair of upper layer nodes of a network, an alternative path through a lower layer of said network for conducting traffic, and for deleting selected paths through the lower layer, said at least one virtual controller device obtaining transport network information provided by a transport layer computation entity computing the feasibility of a new link between said pair of layer nodes using said transport network. The system implements the method of the invention.
