Abstract
A network designing method is provided that decides the slot allocation in a bi-directional ring system through which paths are routed, at minimum total costs for ring systems and for cross connect (XC) connecting them. Routes for a ring candidate and a node base path candidate are created based on connection information regarding nodes and spans and based on demand pairs and hubs (step A ). Thus, an integer programming problem is created and solved (step A ). The solved results are used to decide the number of ring candidates to be installed in bi- and uni-directional ring systems, nodes to which ADMs are installed in each ring system, node base path capacities, and slot numbers allocated to channels routing a bi-directional ring system (step A ).
