 note = {筆者らはこれまで、インターネットと高速専用回線、無線 LAN を併用した通信環境下に広域災害情報共有システム （WIDIS） の構築を行ってきた。本稿では、災害によりサーバやネットワークに障害が発生したときでも、WIDIS を利用できるよう、ロバストネスと可用性を保つ新しい手法について述べる。この手法では、障害の発生したノードと経路を検知のうえ分離を行い、正常なノードとリンクのみで動的再構成を行う。また、この手法をプロトタイプシステムに実装し、実運用に向け評価を行ったので報告する。, So far, we have developed Wide-area Disaster Information Sharing system (WIDIS) on the multihoming environment using Internet, high-speed wide-area network and wireless network to provide more useful information for both the residents and volunteers when the disaster happened. In this paper, we introduce a new method to preserve the robustness and availability of WIDIS even though the some servers and network nodes and links are disordered by disaster. By this method, the failed nodes and lines on the system are detected and isolated. Eventually the remained normal nodes and links are automatically reconstructed. We introduced this method and implemented to WIDIS to improve its robustness and availability. A prototype system was built to evaluate its performance and functionality to verify the realization as real use.},
