Abstract

地理的な位置の表現には,人間にとって扱いやすい間接位置参照と,コンピュータにとって扱いやすい直接位置参照がある.そのため,間接位置参照から直接位置参照へ変換する位置参照サービスが必要になる.既存の位置参照システムは,データの整備や管理・更新を集中的に行うため,コストがかかりすぎる点が問題である.そこで本稿では,位置参照アルゴリズムをネットワーク上の分散サービスとして実装する方法について説明する.分散サービスとすることにより,地域分散管理を行うことができるようになり,スケーラビリティの高いシステムとして動作する.また,実装と実験を行い,分散システムとして安定して動作することを確認した.There are two ways to express geographical locations: indirect location reference and direct location reference. The former is understandable for ordinary people; the latter is suitable for computer systems to manage. Location reference services are required in order to convert indirect location references into direct ones. Since existing location reference systems manage and update location reference data intensively, their high cost is a severe problem. This paper explains the way to implement a location reference algorithm into a distributed service on computer networks. The service runs on distributed servers, thus location reference data can be maintained on each server. We also present experimental results to show that the distributed system is efficient and stable.
