Abstract
Provided is a Universal Plug and Play (UPnP) Internet Gateway Device (IGD). A plurality of IGDs existing in a UPnP network interchange IGD information that is managed in order to provide a gateway service with each other, and thus the bandwidth of a device connected to the Internet can be increased, handover of a device can be successfully performed in the presence of an error of an IGD, and loads can be balanced between a plurality of IGDs. Accordingly, various Internet services can be efficiently provided to the UPnP device.
