Abstract
A gateway selector and a load distribution management device are provided between a user terminal and plural gateway devices. Of response packets received from the plural gateway devices, the gateway selector selects a response packet from a gateway device with a higher priority, according to the priority in a load distribution management table of the load distribution management device. Then, the gateway selector transfers the selected response packet to the user terminal, while discarding a response packet from another gateway device. In this way, it is possible to construct a redundant configuration of the gateway devices, independent of user terminal implementation.
