摘　　要：以太网技术组建城域网,其高可靠性是技术关键.本文通过分析系统冗余度、链路并联冗余和层间串-并联冗余三种方法解决城域以太网的可靠性问题.实验结果证明冗余度为2时网络可靠性最佳;链路可用性越大,能支持的环网节点越多;并论证了层间混合冗余模式同样能提高城域以太网的整体可靠性.High reliability requirement is the key technology in the formation of Metro Ethernet. The essay shows the system redundancy, the link parallel redundancy and the series-parallel redundancy of interlamination can improve the reliability of Metro Ethernet. The experiment showed that system redundancy 2 make the best reliability and the result of the simulation shows that the better availability will support more nodes in ring.Besides series-parallel redundancy of interlamination can also improve the reliability of Metro Ethernet overall.
