— Buffered crossbars have emerged as an advantageous switch architecture mainly due to their scheduling efficiency and capacity to operate directly on variable size packets. Such operation requires crosspoint buffers at least as large as one maximum packet each. When we cannot afford that large crosspoint buffers, we are forced to segment packets. Although(More)
The crossbar is very popular for the implementation of switches with a moderate number of ports. Unbuffered crossbars (IQ-architecture) require complex switch matrix scheduling algorithms that operate on fixed-size cells. On the other hand, buffered crossbars (CICQ-architecture), use small buffers at the crosspoints and provide excellent features;(More)
