Methods for allocating transmission bandwidths of a network are adapted to a network including an office terminal and peripheral terminals. The peripheral terminals communicate with the office terminal by time division multiplexing during a sequence of transmitting cycles. The method includes receiving requested bandwidths from uploading messages delivered from the peripheral terminals, arranging an uploading order of the peripheral terminals based on the uploading messages to obtain a transmitting sequence, adjusting the uploading order of each of the peripheral terminals in the transmitting sequence based on a size of the requested bandwidth to obtain a modified transmitting sequence, and arranging a modified uploading order of the peripheral terminals based on the modified transmitting sequence. 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.

Methods for allocating transmission bandwidths of a network

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.
