摘要

In this paper, a novel architecture of three-Dimensional Virtual Output Queue (3D-VOQ) switch is proposed. The 3D-VOQ switch requires no speedup and provides an exact emulation of an output-queued switch with a broad class of service scheduling algorithms regardless of its incoming traffic pattern and switch size. First, an NxN 3D-VOQ switch was proposed. In this architecture, input queues were designed with a few virtual output queues (VOQ) to avoid Head-Of-Line problems and output sides were arranged using sufficient separate queues. The combination of this scheme makes switch an input/output contention-free architecture. Next, we propose a Small Time-to-leave Cell First (STCF) algorithm of which it can produce a stable many-to-many assignment. It is also demonstrated and illustrated that the proposed 3D-VOQ switch can be used to mimic an exact OQ switch. Finally, analysis and simulation are employed to verify the performance of 3D-VOQ.
