基于开源协议的三层以太网交换设备

Three Layer Ethernet Switching Equipment Based on Open Source Protocol

文章提出了一种采用开源路由协议结合传统硬件平台三层以太网交换机的方案。该方案上层路由协议采用开源Quagga路由协议,系统平台采用Linux操作系统,底层硬件采用博通交换芯片BCM56150,支持二层生成树协议、链路发现协议等二层协议,RIP、OSPF、BGP等三层路由协议以及PIM-SM组播协议,硬件接口可以支持24路千兆以太网电口以及4个万兆以太网光口。

This paper proposes a scheme of using open source routing protocol combined with traditional hardware platform threelayer Ethernet switch.In this scheme,the upper layer routing protocol adopts open source Quagga routing protocol,the system platform adopts Linux operating system,the underlying hardware adopts Broadcom switching chip BCM56150,supports two-layer protocols such as spanning tree protocol and link discovery protocol,three-layer routing protocols such as RIP,OSPF and BGP,and PIM-SM multicast protocol.The hardware interfaces can support 24 channels of Gigabit Ethernet ports and 4 Gigabit Ethernet light ports.
