Abstract
Streams of information are transmitted over corresponding channels of an information network, by associating a number of queues with the channels, enqueuing incoming descriptors representing information to be transmitted over a given channel in a queue associated with the channel, and dequeuing the descriptors from the queues by operation of a scheduler. A small and fixed-size buffer is associated with each channel, and a watermark threshold value corresponding to a minimum occupancy level is defined for each of the transmit buffers. When the occupancy of a given buffer falls below the buffer's threshold value, a corresponding watermark event signal identifying the channel associated with the buffer is produced. The watermark event signals are provided to the scheduler, and information represented by descriptors dequeued by the scheduler are delivered to corresponding buffers according to the order of the watermark event signals provided to the scheduler.
