ABSTRACT:
Methods for allocating transmission bandwidths of a network are provided. The allocation ratio of anticipation bandwidths is adjusted according to the loading of the network to calculate the requested bandwidths, thereby effectively reducing an average delay and enhancing the utility rate of the network. Further, remaining bandwidth of the network is allocated based on maximum used bandwidth and bandwidth compensation of each terminal during the transmission cycle, to allocate excess bandwidth for each terminal. Therefore, the transmission bandwidth allocation is fairer, and delay is reduced. Upstream order of each terminal is transferred based on its requested bandwidth, thereby effectively reducing the average delay.
