Abstract
The disclosed s, structures, and methods are directed to a method and a system for embedding a virtual network onto the substrate optical network comprising embedding the plurality of virtual nodes onto the plurality of substrate nodes in accordance with the plurality of location constraints, computing end-to-end latency associated with a plurality of substrate paths connecting a source substrate node and a destination substrate node, wherein the plurality of substrate paths contain the plurality of substrate links and the plurality of substrate nodes, and embedding a virtual link connecting a source virtual node and a destination virtual node onto the one of the plurality of substrate paths connecting the source substrate node and the destination substrate node, wherein the end-to-end latency associated with the one of the plurality of substrate paths is less than or equal to a maximum allowable latency for the virtual link.
