| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper discusses a method for leveling traffic load of communication links in a distributed management network with multiple controllers. Our study has modeled the distributed management network as a flow network and defined the ratio of flow to capacity in an edge as a load factor. In that network, an Unsplittable flow Edge Load factor Balancing (UELB) problem has been formulated for finding the flow path to minimize the max load factor. However, time complexity of the proposed approximation algorithm is $O(K^3 |E|^3 B)$ ($K$: number of commodity, $E$: number of edges, $B$: the number of data bits), and that time can not be practical. Therefore, this paper indicates the approximate solution to UELB problem, which is faster than the proposed solution. | |
