摘要： A method and device for controlling bandwidth distribution through a switch fabric is provided wherein a plurality of line cards and processor cards are connected through a switch fabric for parallel processing of transmission requests, along with the provision of transmission “credits” allowing for transmitting additional data bytes during a given cycle, which provides efficient and speedy bandwidth distribution, as well as resolution of output contentions. The processors maintain a credit balance which allows flexibility in granting transmission requests to accommodate transmission scheduling and “bursty” transmissions. Processors on both of the line cards and the processor cards normalize the data transmission requirements for both inputs and outputs connected by the switch fabric. Smoothing of data transmission is provided using a time-weighted buffer.
