摘　　要：总结了IP RAN端到端L2+L3和L3到边缘2种典型组网方案;通过对多故障场景保护方式的模拟分析,给出了光缆同路由或组网光口同板卡选择的建议;提出了"业务左右对称承载"的理想组网模型,大大提高了IP RAN的利用率。It summarizes two typical networking architecture：L2＋L3 and L3 to the edge. Through multiple network fault scene protection mode simulation analysis, it gives suggestion about networking cable and physical optics selection. Finally it proposes an ideal networking model with the characteristics of business bearing symmetrically, which greatly improves the utilization rate of IP RAN network.
