Method for load distribution

This invention provides a method for a load distribution, wherein a load distribution device performs the load distribution to a plurality of servers. The method comprises steps of: firstly, calculating a max amount of the load distribution of a first stage and performing the load distribution of the first stage; then, determining whether an actual distributed amount of each of the plurality of servers in the first stage reaches the max amount of the load distribution of the first stage; if yes, subsequently calculating a max amount of the load distribution of a next stage and determining whether an actual distributed amount of each of the plurality of servers in the next stage reaches the max amount of the load distribution of the next stage; and continuously determining whether the actual distributed amount of each of the plurality of servers in each stage reaches the max amount of the load distribution of each stage, wherein the max amount of the load distribution of each stage is less than or equal to the
