PROBLEM TO BE SOLVED: To provide a load distribution device and a load distribution method capable of reducing processing TAT of a request signal while keeping a processing load of a processing server constant.SOLUTION: A load distribution device 100 includes: an information storage section 130 storing a load limit value as a limit value for processing of a low delay server; a server information acquisition section 120 acquiring load information of the low delay server; a take-over signal number calculation section 111 calculating a take-over signal number S which is the number of signals which should be assigned to a high delay server but are actually assigned to the low delay server, in a range not exceeding the load limit value, on the basis of the number of high delay servers, the number of low delay servers, a maximum value of the acquired load information, and a processing server load fluctuation rate A indicating load fluctuation of the low delay server; and an assigning function section 110 performing assignment of signals of the calculated take-over signal number S from the high delay server to the low delay server.SELECTED DRAWING: Figure 1 【課題】本発明は、処理サーバの処理負荷を一定以下に保ちつつ、要求信号の処理ＴＡＴを低減することができる負荷分散装置および負荷分散方法を提供する。【解決手段】負荷分散装置１００は、低遅延サーバの処理の限界値である負荷制限値を記憶する情報格納部１３０と、低遅延サーバの負荷情報を取得するサーバ情報取得部１２０と、高遅延サーバの台数と、低遅延サーバの台数と、取得した負荷情報の最大値と低遅延サーバの負荷変動を示す処理サーバの負荷変動率Ａとに基づいて、負荷制限値を超えない範囲で、高遅延サーバに振り分けるべき信号を低遅延サーバに振り分ける肩代わり信号数Ｓを算出する肩代わり信号数算出部１１１と、算出した肩代わり信号数Ｓ分を、高遅延サーバから低遅延サーバに振り分ける振分機能部１１０と、を備える。【選択図】図１
