Abstract : Resource Allocation/ Assignment in optical communication is extremely essential to enable effective and secure communication in optical networks. There have been various strategies suggested by people around the world and research for which is aggressively on-going and thriving. In this paper, we will be discussing about the enhanced quantum key distribution (QKD), Time Sliding Window (TSW), Software Defined Network Controller (SDN) and its implementation in Routing, wavelength and time slot assignment (RWTA) networks. As we know that with the advancements in technology and with advent of quantum computers, the present cryptographic techniques are vulnerable to hacking and eavesdropping, which is a grave concern when it comes to implement this powerful technology in the finance and the defence industry. Therefore, there is an utmost need of secure mechanism for data transmission in optical networks. To explain further, here we address QKD implementation with enhanced AES algorithm and Software defined Networking (SDN) based QKD enabled architecture for efficient management of resources/data. With the implementation of such an architecture the issue of time conflict possibility in case of dynamic requests may arise, this issue has been addressed with time-sliding window mechanism as a possible solution.
