| Popis: | Typical optical transport networks dimensioning is performed disregarding the client to line ports interconnection restrictions imposed by the node architecture deployed. After the grooming and routing optimization, equipment is mapped in order to implement the obtained solution. However, as some node architectures can impose restrictions in the client to line ports interconnection, some grooming configurations may be unfeasible to map. This is particularly relevant in multi-period scenarios where traffic changes between periods and capacity is already installed at specific modules. In this work, we present an integer linear programming (ILP)-based framework that minimizes the additional number of line interfaces required to overcome unfeasible mappings. The node architectures considered are non-blocking electrical cross connect (EXC), partial non- blocking EXCs, EXCs with extendable backplanes, and EXCs with interconnection via high bit rate client ports. Using the proposed framework we evaluate the impact of node architecture flexibility in the number of line interfaces required. |
