    摘要： A station side communication device includes allocation judgment means and history management means. The allocation judgment means executes band allocation judgment for each subscriber device at each data collection cycle. The history management means makes a history of request amount increases from the band request amount obtained from more than one data collections and the allocation amount for it by the allocation judgment means and represents the band request amount to be subjected to the allocation judgment by decomposing it into the plurality of request amount increases indicated by the history. Thus, it is possible to detect a delimiter of packet data in the request data amount and perform allocation to a part of the request data amount, which enables allocation of an upstream band so as to effectively use a shared band and reduce the data transmission wait time.
