Research Abstract

本研究では、ネットワークで結ばれた計算機群で構成される分散システムにおける耐故障を有するアルゴリズムの基礎的な研究を行なった。特にメッセージ消失やメモリ内容消失などの故障からの自動回復、ならびにネットワーク形状や参加ノードの動的な変化に自動追従する仕組みを中心に研究を進めてきた。中でも、Peer-to-Peer型のネットワークに焦点を当て、その特性に合致する耐故障分散アルゴリズムを研究した。

では、Peer-to-peer型のネットワークにおける共有オブジェクト検索方式を提案し、その故障耐性ならびに動的ネットワークでの性能を理論的な側面より示した。提案手法は、従来手法のDHT方式やGnutella方式とも異なる第三の方式であり、今後大きな進展が期待できる方式である。
