The purpose of a OSN crossconnection configuration optimization is to enhance the performance of a network, meaning in this context is that customization and optimal possibilities would be used for routing, traffic reduction and service speed enhancement. This is achieved by studying history where data flows begin and where they need to end, associating them with OSN and crossconnection routes that have minimal distance. There are optimal heuristic ways within the given restrictions such as link bandwidth, signal level, and SLAs. Better dynamic crossconnections and their reconfiguration improve the optical network performance.
