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.

An address translation method for use in a system including a plurality of cluster nodes and including the steps of: at a source node, receiving over a first network a communication with a first destination address having an index portion and an offset portion, wherein the index portion includes a partition number portion; providing an address mapping table which maps a plurality of indexes to a corresponding plurality of node ID's, each of the plurality of node ID's identifying a different one of the plurality of cluster nodes; using the index portion from the first destination address as an index into the address mapping table to identify a node ID, wherein the identified node ID identifies a destination node; appending the identified node ID to the first destination address to generate a second destination address; and using the second destination address to send information to a second network of the destination node.
