Abstract
An amount-of-data identifying portion identifies the amount of data transmitted by referring to a specific portion in the upper layers of the information transmitted from the terminal of a LAN, and a bandwidth control line monitor portion calculates the band which is necessary for communication. Communication between LANs is executed through the number of wide area network interface portions which is determined on the basis of the calculated band. In the case that the communication is performed after securing the band corresponding to the traffic characteristics (transfer speed, etc.) declared to the network, the amount-of-data identifying portion identifies the amount of data transmitted by referring to a specific portion in the upper layers of the information transmitted from the terminal of a LAN, a traffic characteristics calculator calculates the traffic characteristics on the basis of the amount of data transmitted, a traffic characteristics declaring portion declares the calculated traffic characteristics to the network, and the network communicates on the basis of the declared traffic characteristics.
