Claim One:
1. A method for topology aggregation by a routing controller in an optical network, comprising the steps of: obtaining an adjacent matrix for each wavelength in used for communication within a real topology of nodes in a routing domain, communication between said nodes managed by the routing controller; obtaining a link-diversity path number between each pair of border nodes in the real topology from the adjacent matrices using a maximum flow algorithm; obtaining a connectivity matrix by utilizing said link-diversity path numbers and constructing a corresponding full-mesh topology; and performing topology compression on said full-mesh topology, said topology compression further comprising the steps of: determining structural parameters of a bi-directional shuffle-net topology; initializing said bi-directional shuffle-net topology by utilizing said structural parameters; and optimizing said bi-directional shuffle-net topology by utilizing said connectivity matrix.
