摘要:

为了使交换机保证服务质量并提高交换速率,提出了一种新型组合输入交叉点排队(CICQ)的交换结构,并运用理论证明的方法分析了它的性能. 分析结果表明,重端口数为2的CICQ交换结构能在无需内部加速的情况下精确地模仿输出队列交换机,从而解决了服务质量与交换速率之间的矛盾.

关键词: 组合输入交叉点排队交换机, 输出队列交换机, 调度算法

Abstract:

In order to acquire high speed switching and guarantee quality of service simultaneously, a new combined input and crosspointqueued switch is given. Based on theoretical analyzing, we show each port with a duplicated number of two is sufficient to mimic outputqueued switch, which can solve the problem between switching line rate and quality of service.

Key words: combined input and crosspointqueued switching, output queued switching, scheduling algorithm
