The disclosed apparatuses and methods are directed to embedding of virtual links in an optical network. The method comprises: receiving an adaptation request for a virtual link within a virtual network embedded on an optical substrate network; generating a plurality of candidate embeddings based on a topology of the substrate network and a current embedding of the virtual link, each candidate embedding satisfying the adaptation request; determining a total cost of each candidate embedding based on a disruption cost of the candidate embedding; and selecting, as a new embedding, a candidate embedding from the plurality of candidate embeddings in accordance with the determined total cost of the selected candidate embedding.

System and method for elastic optical networks

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.
