Abstract: Network load balancer is efficient to enhance network performance. This paper studies different load balance systems and algorithms. By comparing those load balance algorithms, it adopts dynamic feedback load balance scheduling algorithm based on agent. This system is designed by combining with Intel IXP425 network processor and VxWorks5.5 embedded operating system. In laboratory environment, the balancer is used to balance proxy server load and has a good performance. Experimental result indicates the design is appropriate to use as a medium-sized network load balance equipment.

Key words: dynamic feedback load balance, network processor, proxy server
