| 中文摘要: |
| 互连网络,例如3-D torus拓扑结构,已成功应用于可扩展路由器的设计中.但是,3-D torus结构在实际应用时存在设计缺陷,扩展规模受到了限制.提出了一类新型的交换架构,称为蜂巢式路由器.基本蜂巢结构存在一些问题,通过引入镜像点可以有效解决,还给出线卡的具体设计方案.最后介绍了该架构下几类路由算法的设计.蜂巢结构表现出优秀的扩展能力和容错性,非常适合可扩展路由器的设计. |
| 英文摘要: |
| The switching fabric in the Avici TSR uses a 3-D torus topology with each line card carrying one node of the torus.It requires no centralized switching fabric,whereas its scalability is limited by the bisection bandwidth.This paper proposes a novel architecture called Cellular Router (CR).There exist some problems with the basic CR architecture.They are solved by introducing Mirror Points (MPs).This paper also gives the design of line cards in this architecture.In the end,the design of routing algorithms is introduced on this architecture.The CR architecture shows excellent scalability and fault tolerance.It is a promising choice for the design of scalable routers. |
