STATION SIDE COMMUNICATION DEVICE

摘要

The station-side communicating apparatus according to the present invention includes an allocation determining unit that determines a bandwidth allocation for each of the subscriber devices in each data-collection cycle; and a history managing unit that takes a history of a request increment from the bandwidth request amount acquired from more than one time of data collections and an allocation amount allocated by the allocation determining unit for the bandwidth request amount, and presents bandwidth request amount to be a target for the allocation determination to the allocation determining unit by dividing the bandwidth request amount into a plurality of request increments indicated by the history. With this configuration, because a detection of a segment of packet data in the request data amount and execution of an allocation for a portion of the request data amount is possible, the upload bandwidth can be allocated in such a manner that the data-transmission waiting time is reduced while effectively using the shared bandwidth.
