Abstract
In one or more embodiments, one or more systems of a physical optical network that may implement and/or manage a virtual optical network (VON) that interconnects multiple data centers. Virtual nodes based the multiple data centers to be interconnected may be determined, and each of the virtual nodes may be mapped to at least two physical nodes of the physical optical network. Virtual links for pairs of the virtual nodes may be determined, and each virtual link may be mapped to at least one optical network connection of the physical optical network. At least one of a physical node impairment and an optical network connection impairment that is associated with a first physical node implementing a first virtual node may be detected, and the first virtual node may be implemented via a second physical node.
