Each VON request may include one or more virtual nodes and one or more virtual links. The virtual nodes may have one or more candidate nodes corresponding to a physical optical network. The method may also include identifying mapping patterns for VON requests by iteratively assigning each virtual node to one of their candidate nodes for each combination of candidate nodes and assigning each virtual link to corresponding physical links. The method may also include formulating a first set of constraint equations based on mapping patterns for the VON requests and formulating a second set of constraint equations based on physical optical network constraints. The first and second set of constraint equations may be solved by satisfiability modulo theories to obtain a mapping 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 an optical network may include receiving one or more virtual optical network (VON) requests.
