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。
以太網技術組建城域網,其高可靠性是技術關鍵。本文通過分析繫統冗餘度、鏈路併聯冗餘和層間串-併聯冗餘三種方法解決城域以太網的可靠性問題。實驗結果證明冗餘度為2時網絡可靠性最佳;鏈路可用性越大,能支持的環網節點越多;併論證瞭層間混閤冗餘模式同樣能提高城域以太網的整體可靠性。

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.
