Data Center Network architectures (DCN) are evolving for increased scalability, performance, and low network complexity. In this paper, the authors propose HyScale, a switch-centric DCN architecture using hybrid optical networks. HyScale employs Optical Burst Switching and Optical Circuit Switching technologies for transmitting low and high volumes of data respectively in a data center. The proposed architecture is highly scalable, recursively defined, fault-tolerant, and has low network complexity. It also has a multitude of desirable graph-theoretic properties like high bisection width, and low diameter.
