Abstract
A packet forwarding device stores a predetermined threshold and a predetermined condition value of a first wide area network (WAN) port, and forwards packets that comply with the predetermined condition value via the first WAN port and forwards packets that do not comply with the predetermined condition value via a second WAN port. The packet forwarding device forwards some of the packets that do not comply with the predetermined condition value via the first WAN port in order to balance loads of the first and second WAN ports if the traffic value of the packets forwarded via the first WAN port is equal to or less than the predetermined threshold.
