| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide distributed processors capable of swiftly carrying out load distribution.SOLUTION: A distribution device stores a piece of area information for each area where a consistent hash space is segmented which is associated with a server identifier for identifying respective server which covers respective area. When a first server is detected, the load of which exceeds a threshold level, the distribution device identifies an area to be covered to the first server according to the area information. The distribution device adds a server identifier to a second server to the area information while associating with the cover area of the first server.SELECTED DRAWING: Figure 4
【課題】負荷分散を迅速に実行することを課題とする。【解決手段】振分装置は、コンシステントハッシュ空間が分割される領域ごとに、各領域を担当する各サーバを識別するサーバ識別子を対応付けた領域情報を記憶する。振分装置は、負荷が閾値以上である第１のサーバが検出された場合、領域情報にしたがって、第１のサーバが担当する担当領域を特定する。振分装置は、第１のサーバの担当領域に対応付けて第２のサーバのサーバ識別子を、領域情報に追加する。【選択図】図４ |
