Abstract (in Japanese) (See Japanese page) 
(in English) For topologies of interconnection networks, folded Clos ones are common in data centers but strange topologies was and still are used in super computers. As it is easily provable that, for uniform all-to-all communication, butterfly topology is best and for biased all-to-all communication, Clos topology is best, the proofs are presented. Comparison to other topologies are also presented.
