Outline of Final Research Achievements

In this research project, we developed new network control technologies for content oriented networks which was in a start phase of its research on architecture at the starting point of this research. Our research project was based on the new viewpoint that cooperation of application layer and networks, such as lower layer including network layer, is one of the most important technical issues for realizing the practical use of the content oriented network. More specifically, we developed new technologies in the following three aspects, cache control, congestion control methods, and adaptive rate control by leveraging cooperation of applications and networks. These three technological elements are very important for effective content distribution, which is the most crucial technical issue for the current Internet because traffic volume of content distribution is major part of the whole Internet traffic.

Academic Significance and Societal Importance of the Research Achievements

インターネットトラヒックのほとんどを占めるコンテンツ配信に対し、ネットワーク(NW)とエンドホストが連携することにより、単なるNW資源の有効利用にとどまらず、動画像品質などのユーザが享受する性能の大幅な改善が図れることを明らかにしており、学術的に大きな意義がある。本研究課題はコンテンツ指向NWの実用化に向けた重要な技術を開発し、コンテンツ流通なくては成り立たない現代社会に与える社会的意義は大きい。
