Abstract

Abstract:

Buffered switches are analyzed firstly, and then a new scheduling algorithm based on unstable virtual output queue and unstable cross-point buffer is presented. The delay and stability performance are investigated carefully by simulations. It is shown that the new scheduling algorithm can offer very good performance on average delay and stability for no-uniform traffic with Bernoulli arrivals. The shortcoming of round robin-round robin algorithm is completely solved, and useful to design high performance combined input and crosspoint-queued (CICQ) switch.

Key words: combined input and crosspoint-queued switch, delay, virtual output queue
