NETWORK SYSTEM, METHOD, DEVICE AND PROGRAM

摘要

The present invention provides a system in which addition of a network facility due to an increase in traffic is reduced and mobility for traffic offloading is implemented. Provided a switch between a first network (CN) and a second network (PDN) and offloading determination means that determines whether or not to offload traffic for the first network, and configures an offload path to bypass the first network for the switch when the offloading is performed. When the traffic is offloaded, the switch forwards a packet to be offloaded to the offload path.
