Space Eecient Fair Queuing by Stochastic Memory Multiplexing
We propose a new scheme for multiplexing buuer space between ows contending for the same output port. In our scheme messages of the diierent ows are serviced in either Round-Robin or almost Round-Robin order, thus supporting fair queuing. Our scheme is both simple for hardware implementation and achieves high buuer space utilization (by taking advantage of statistical multiplexing between the ows). Therefore our scheme enjoys from both the simplicity of the hardware queue per ow scheme and the space eeciency of the linked-list based dynamic scheme, suggesting an attractive compromise between the two extremes.
