Method and system to realize gateway dynamic load sharing

The present invention relates to a gateway for implementing dynamic load balancing method and system, by providing a plurality of virtual MAC address in the same virtual new backup set having a plurality of gateway devices, so that the host device on which data can be packets of different forwarded to the external network gateway server, gateway to achieve dynamic load balancing. The present invention is directed to the existing gateway backup and load sharing network management burden will increase, and the cost of network bandwidth, a gateway device, there is provided a gateway implementing dynamic load balancing method and system, the user can simplify the configuration and reduce the data transmission bandwidth of the network occupancy, improve the forwarding performance of gateway devices.
