PROBLEM TO BE SOLVED: To distribute copying processing of a packet included in an identical flow.SOLUTION: A packet copy function block of a packet relay device includes: plural duplication parts; a load distribution part; and plural accumulation parts corresponding to the plural duplication part respectively. The load distribution part distributes the packet to any one of the plural accumulation parts on the basis of an accumulated remaining copy amount corresponding to each of the plural duplication parts, which is calculated on the basis of the number of copies of the packets accumulated in each of the plural accumulation part.SELECTED DRAWING: Figure 4 【課題】同一フローのパケットにおける複製処理を分散して行う。【解決手段】パケット中継装置のパケットのコピー機能ブロックは、複数の複製部と、負荷分散部と、複数の複製部それぞれに対応している複数の蓄積部とを備える。負荷分散部は、パケットを複数の蓄積部それぞれに蓄積されている蓄積パケットのコピー数を元に算出された複数の複製部それぞれに対応している累積残コピー量に基づいて複数の蓄積部のいずれかにパケットを振り分ける。【選択図】図４
