Input queued (IQ) switch architectures with virtual output queues (VOQ) can scale up to very high speed. With the increase in density of VLSI, buffering at Crossbar cross points for one cell or packet become possible.

- 帶虛擬輸出隊列(VOQ)的輸入隊列(IQ)交換結構可按比例地達到很高的速度,甚大規模集成電路(VLSI)集成度的不斷提高使得對于Crossbar的交叉點(diǎn)在硬件上為每個(gè)信元或包留有足夠的緩存成為可能。
