Abstract: Aiming at solving the load distribution problem in the distributed systems，through the research of the ecological
predator-prey model，a distributed control network load banancing algorithm based on ecological difference equation mathmatical
model is proposed.The algorithm corresponds the two nodes to the predator and prey of ecosystem，and corresponds the
load information volume of nodes to ecosystem populations，dynamiclly adjusts the load information volume of nodes using
ecological difference equation mathmatical model of two species and achieves network load balancing.Experiments have
proved the validity of this algorithm.

摘要： 针对分布式系统的负载分配问题，通过对生态捕食模型的研究，提出一种基于生态差分方程数学模型、分布式控制的网络负载平衡算法。该算法将两节点对应到生态系统的捕食者和被捕食者，将各节点的负载信息对应到种群规模，利用两种群生态差分方程数学模型动态调整节点负载信息，达到网络负载平衡。实验证明了该算法的有效性。
