Abstract: Abstract Recently a class of scalable multi-star optical networks is proposed. Inthis network class nodes are grouped into clusters. Each cluster employs aseparate pair of broadcast and select couplers. The clusters areinterconnected via fiber links according to a regular topology. This approachefficiently combines time and/or wavelength division with direct spacedivision. One important issue for this network class is the conflict-freechannel set assignment that maximizes spatial re-use of channels. This paperstudies the conflict-free channel set assignment for the hypercube clusterinterconnection topology. The approach in this paper is novel and isconjectured to be optimal.
