Previous work by Chang et al. showed that the symmetric 3-stage Clos network is SNB if and only if it is WSNB under any of the five strategies: save the unused (STU), packing (P), minimum index (MI), cyclic dynamic (CD), and cyclic static (CS). The work also proved that the multi-log���������������� network is SNB if and only if it is WSNB under the STU, P, CD, and CS strategies. In this paper, the P and STU strategies are extended to six new strategies that give the same number of middle crossbar as SNB. Some special properties of the log_d N network are also described.
