Research for a design of high-speed packet switch for next-generation networks

介绍了一种高性能ATM交换机的新设计，它可以作为下一代网络中大容量路由器的交换引擎。我们提出了一种用于输入队列ATM交换机的新型调度算法，它保留了输出端口上单元的传输时间，而不像传统的调度算法只保留输出队列上的当前时间，并且通过仿真表明，我们的算法可以克服传统的调度算法，如i SLIP。我们还展示了一种用于Benes开关的高速开关控制电路的新设计，该电路可以取代输入队列交换机中使用的传统交叉开关，以降低开关的复杂性。

A new design of high-performance ATM switch, which serves as a switching engine of large capacity routers for next generation networks is described. We have proposed a novel scheduling algorithm for input-queued ATM switches, which reserves transmission time of cells at output ports unlike conventional scheduling algorithms that reserve only present time at output queuem and have shown through simulations that our algorithm can overcome conventional scheduling algorithms such as i SLIP. We have also shown a new design of high-speed switch control circuit for Benes switches, which can replace conventional crossbar switches used in input-queued switches for their reduced switch complexity.
