Abstract
A bandwidth allocator for communicating with communication terminals by transmitting and receiving data packets over a line having its communication bandwidth divided into periods of time of a predetermined length. The allocator includes a controller controlling allocation of the bandwidth by using allocation grants as the periods of time. The controller includes a scheduler scheduling the allocation grants so as to cause one allocation grant to partially overlap as a shared grant with another allocation grant adjacent to the one allocation grant. Thus, the bandwidth allocator can minimize allocation loss, otherwise caused by no allocation to an allocation grant, and improve the use efficiency of the bandwidth.
