Outline of Final Research Achievements

We proposed a salience-based controller placement method for distributed SDN. We revealed that our proposal determines the controller placement which shortens average hop-counts between switches and their nearby controllers, according to salience, that is, one of characteristic measures of links in graphs, in a short time.
And also, we proposed controller addition/migration method based on salience to correspond to increment/decrement of nodes. This method can be also applied for designing network slices on NFV (network function virtualization) infrastructure. As a result of simulation, we revealed our proposal keeps costs for slice reconstruction low, that is, the numbers of added/migrated controllers are kept low nevertheless the number of VNF (virtualized network function) servers are changed when the slice users increase/decrease.

Academic Significance and Societal Importance of the Research Achievements

今後のICT基盤を支える重要な要素技術である、SDNによる柔軟なトラヒック制御やNFVによる仮想資源を動的割当の実現には、監視と制御を行うコントローラが重要な役割を担う。コントローラにかかる負荷の集中を避けるには、複数のコントローラを分散配置することが有効だが、従来の整数計画法(施設配置問題)によるアプローチでは多大な計算時間が必要となる。そこで本研究計画では、顕著性という複雑系科学の知見を利用し、最適化問題に依らない新たなアプローチで、計算時間を抑えつつ分散型コントローラの配置を決定できることを示した。この知見は情報ネットワークに限らず、様々な施設配置問題に関連する課題への応用が期待できる。
