Abstract

A load balancing system and method is provided. The load balancing system includes a core network, CPEs (customer premise equipments), user equipments, and a load balancing equipment. The CPEs receive signals from the core network and connect to each other through a network topology. The user equipments are connected to the CPEs. The load balancing equipment is connected to one CPE, and the load balancing equipment confirms a throughput limit of each CPE and includes a data analysis module and a processing unit. The data analysis module receives network parameters between the CPEs and the user equipments, and calculates premise throughputs of the CPEs. The processing unit generates a route control table according to the premise throughputs. According to the route control table, the CPEs adjusts signal transmission between the CPEs and the user equipments to balance the premise throughputs of the CPEs.
