| Outline of Final Research Achievements |
In future translucent elastic optical networks, a programmable multi-carrier generator (PMG) and virtualized elastic regenerator (VER) replacement algorithm will be key technologies. We proposed PMG based on common optical frequency references that achieve both the precise sub-carrier spacing and the flexible center frequency assignment, and demonstrate a proof of concept experiment. In addition, we proposed VER-placement and routing and spectrum assignment algorithms, and numerically evaluated the effectiveness of the algorithms by applying them to protected and un-protected networks.
