Abstract
A method of and system for determining a path through which to route a connection in a photonic network in which optically viable photonic paths of one or more physical links are determined and considered as 'virtual' links in a 'virtual' topology. Routing is then performed using the “virtual” topology rather than the physical topology to compute “virtual” paths of one or more “virtual” links.
