The mapping solution may include one mapping pattern for each VON request and each mapping pattern may include an ordered list of physical nodes. The method may also include formulating inequality constraint equations based on physical links that are shared by multiple virtual links. The method may also include formulating range constraint equations for each virtual link based on a physical link for each virtual link with a lowest number of optical transmission slots such that each virtual link occupy a same optical transmission slot across all physical links that are traversed by the virtual link. The inequality and range constraint equations may be solved with satisfiability modulo theories to obtain a slot assignment solution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Provisioning virtual optical networks","description":"A method of provisioning a network may include receiving a mapping solution for one or more virtual optical network (VON) requests including virtual nodes and virtual links.
