Electrical switching, when used to interconnect tens to hundreds of pods (each having a thousand of servers) in the core of a datacenter, incurs a high cost and power consumption and is expected to be replaced with optical switching soon. In this paper, the authors consider hypercube-based interconnection using optical switches in the core and study novel routing and wavelength assignment schemes for a new paradigm called Labeled Optical Burst Switching with Home Circuits (LOBS-HC). In particular, they propose a simple scheme called complementary HC assignment (CHA) for a 2-dimensional cube and ring, and extend the study to a n-cube (n > 2) and Generalized HyperCube (GHC) by applying the concept of Spanning Balanced Trees (SBTs).
