| Outline of Final Research Achievements |
This research has developed an adaptive link rate switching method to reduce power consumption of a network that is constructed by SDN (Software Defined Network) switches and belongs to an organization such as a university to connect between organization's departments and also between a department and an external network. A communication experiment showed that the total power consumption applied by some 24-hour traffic pattern assumed as a campus network's one is reduced by 12.39% compared to the normal network without any adaptive link rate switching methods.

| Academic Significance and Societal Importance of the Research Achievements |
ネットワーク機器の省電力化とネットワーク性能の向上はトレードオフの関係にあり，通信機器の消費電力を削減すると，通信速度の低下や遅延の増加といったネットワーク性能の低下を招くことになる．本研究で開発した方式によって，組織内ネットワークの消費電力を削減するものであり，マルチパスを利用して，消費電力を過剰に増やすことなく，最大通信速度を段階的に増減する手段を提供することから，その学術的意義や社会的意義は大きい．
