Data center driven by optical circuit switching network, or optical data center, is emerging as an alternative to traditional data center where the electrical packet switching network is already overwhelmed by bulk data transfer. Optical data center promises high bandwidth capability, but it is set against circuit reconfiguration delays, which makes circuit management non-trivial. Optical circuit scheduling must effectively manage traffic over various architectures, traffic patterns and data center sizes. Unfortunately, the state-of-the-art circuit scheduling algorithms are not providing satisfactory solutions. They either suffer from poor scalability and bad scheduling choices under certain traffic patterns, or simply lacks the ability of adapting to different architectures. We propose Decomp, a circuit scheduling algorithm for optical data center. In contrast to the previous algorithms, Decomp remains robust under various architectures, traffic patterns and scales. It promotes sharing of the optical resources among traffic, achieving responsive performance while preserving network utilization at low computational cost. Compared with existing algorithms, Decomp is a more adaptive, robust, and scalable circuit management solution for the next-generation optical data center networks.
