A Partially Buffered Crossbar packet switching architecture and its scheduling
The crossbar fabric is widely used as the interconnect of high-performance packet switches due to its low cost and scalability. There are two main variants of the crossbar fabric:...

Strong Performance Guarantees for Asynchronous Crossbar Schedulers
– Crossbar-based switches are commonly used to implement routers with throughputs up to about 1 Tb/s. The advent of crossbar scheduling algorithms that provide strong performance...

Long Round-Trip Time Support with Shared-Memory Crosspoint Buffered Packet Switch
— The amount of memory in buffered crossbars in combined input-crosspoint buffered switches is proportional to the number of crosspoints, or O(N2 ), where N is the number of port...

Adaptive Max-Min Fair Scheduling in Buffered Crossbar Switches Without Speedup
— A good crossbar switch scheduler should be able to achieve 100% throughput and maintain fairness among competing flows. A pure input-queued (IQ) non-buffered switch requires a...

Shared-Memory Combined Input-Crosspoint Buffered Packet Switch for Differentiated Services
— Combined input-crosspoint buffered (CICB) packet switches with dedicated crosspoint buffers require a minimum amount of memory in the buffered crossbar of N2 × k × L, where N...
