Abstract (in Japanese) (See Japanese page) 
(in English) Servers in a data center cooperate with each other to handle a large data, and the traffic pattern between servers changes significantly within a second. To keep the performance of the data center, sufficiently large bandwidth should be provided between any server pairs even in such frequent and significant traffic changes. Because of too frequent traffic changes, the central control cannot be applied to handle such traffic changes.
In this paper, we propose a method to provide a sufficiently large bandwidth without central control. In this method, we preconfigure the multiple logical topologies which are the subset of the physical network. Then, each node selects the logical topologies used to send the traffic based on the traffic information monitored directly by it. In this paper, we also propose a method to configure the logical topologies for our routing method. In this paper, we demonstrate that our method can provide a larger bandwidth than ECMP.
