Patent ID: 6950435

Claim:
A communication device comprising: a storage section for storing all bandwidths allotted individually to a plurality of nodes, said nodes including a local station and accommodated in a connectionless network; a bandwidth computing section for obtaining from said storage section bandwidths BWt and BWr, which are allotted respectively to said local station and a destination included in said plurality of nodes, said local station being a transmitting party of transmission information, and also obtaining from said storage section a sum total ΣBW of bandwidths allotted to all nodes other than the destination and for computing a transmission bandwidth (=BWt·BWr/ΣBW) to be applied to transmission of the transmission information, based on these bandwidths BWt and BWr and the sum total ΣBW; and a transmitting section for shaping said transmission information and transmitting the transmission information to said connectionless network within the range of the transmission bandwidth computed by said bandwidth computing section.
