IP承载网常见的问题主要是 IP路径中断、 带宽不足、 传输质量差、 通信时 延长、 路由器错误修改报文等。 不管是哪一类问题， 问题定位思路基本上都是 一样的，都必须根据业务管理网络的质量告警与 IP承载网网络拓朴图分析清楚 故障路径涉及到的设备， 然后逐一排除。
本发明实施例提供了一种方法及设备， 通过设置 IP业务质量监测设备， 能 实现业务管理网络和 π 载网之间的互动， 实现业务质量和 载网的质量进 行关联， 实现动态的呈现 IP承载网拓朴连接信息， 检测到网络异常时除了发送 告警以外， 同时还把与异常相关的网络、设备状态在系统上实时显示出来， 电 信业务运维人员仅需根据异常网络或者设备的图标，逐级深入分析便能得到问 题的结症所在， 极大简化了 IP承载网络的运维困难。
通过采集 IP QoS信息， 可以实时统计核心网设备之间的流量总和， 这对网 络健康检查、 网络调整划、 网络评估优化提供有力的数据支撑。
通过定位问题， 可以实时检查网络的通信质量， 当某一个 IP承载路径出现 质量下降时（如丟包率过高、 时延过大、 发现错包等）， 系统会主动定界故障 所在的网络节点， 并上报告警或提示信息。这样可以做到在网络恶化之前快速 发现问题和定界问题， 便于用户进行排查处理， 消除隐患， 避免事故的发生或 减少事故的影响时间。 本领域普通技术人员可以理解：实现上述方法实施例的全部或部分步骤可 以通过程序指令相关的硬件来完成，前述的程序可以存储于计算机可读取存储 介质中， 该程序在执行时， 执行包括上述方法实施例的步骤； 而前述的存储介 质包括： ROM、 RAM, 磁碟或者光盘等各种可以存储程序代码的介质。
