Abstract
In controlling data packet transmission for a passive optical network, a controller provides memory access and flow control of packet data from a host memory to an external optical network device, such as an optical line termination, optical network unit, or optical network termination. The controller is programmed to control packet data flow through the transmission buffer by resizing the transmission buffer to compensate for increases or decreases in bandwidth demand. For example, the transmission buffer may include a plurality of FIFOs, each of a different transmission container type and each capable of having a different bandwidth allocation, which allocation is changed by the controller in response any one of the FIFO's usage levels increasing above a high threshold or decreasing below a low threshold.
