Constructing high availability application servers

Application servers such as a mail server in the integrated network are required high availability because the server failure stops all systems in the network. Adding redundant network interfaces and service program, our application server keeps their service when a server get into troubled. We implement these approaches on our network and evaluate its efficacy under real network system operation. In consequence, routing schemes for file servers can reduce roundabout routing, and high availability application servers have been continued minimum level services for users in the network.リサーチレポート（北陸先端科学技術大学院大学情報科学研究科
