Scheduling in Non-Blocking Buffered Three-Stage Switching Fabrics
Three-stage non-blocking switching fabrics are the next step in scaling current crossbar switches to many hundreds or few thousands of ports. Congestion (output contention) management is the centralExpand

Scheduling in switches with small internal buffers
Unbuffered crossbars or switching fabrics contain no internal buffers, and function using only input (VOQ) and possibly output queues. Schedulers for such switches are complex, and introduceExpand

Variable packet size buffered crossbar (CICQ) switches
One of the most widely used architectures for packet switches is the crossbar. A special version of it is the buffered crossbar, where small buffers are associated with the crosspoints; thisExpand

Weighted fairness in buffered crossbar scheduling
The crossbar is the most popular packet switch architecture. By adding small buffers at the crosspoints, important advantages can be obtained: (1) crossbar scheduling is simplified; (2) highExpand

Distributed WFQ scheduling converging to weighted max-min fairness
This paper studies the fairness properties of distributed WFQ scheduling in buffered crossbars. Using a fluid model, we prove that these networks converge to ideal weighted max-min fair allocation.Expand
