Hardware Accelerated Impairment-Aware Control Plane for Future Optical Networks

In this letter, a hardware accelerated GMPLS based and impairment-aware control plane suitable for optical networks with concurrent lightpath requests support is proposed and evaluated. It outperforms the software version by 80 times in the order of sub-seconds. The high acceleration rate, simultaneous requests support, scalability and low computation time variance are the key features of this tool.
