Abstract: In order to deal with the distributed flow load balancing problem in multi-node systems including routers, an efficient self-adaptive algorithm is given based on feedback. Through sessions, the algorithm can get load mission groups. Based on feedback, it assigns connection missions, adjusts load parameters and attains load balancing. The key technologies are given as the fast port detection and the initialized load balancing method. Performance analysis and simulation results show the algorithm has lower system cost and better load balancing factor.

Key words: feedback, distributed, load balancing
