| 摘 要： | 提出了一种利用链路跟踪检测技术并结合策略路由监控本地网络到多个ISP网络连通性的技术方案，克服了传统的使用静态路由方法对于因某一ISP网络发生故障时，无法实现路由实时检测和瞬时切换通路的技术缺陷，有效地实现了多出口网络的链路互备和负载均衡，从根本上解决了数据中心断网的难题。结合典型实例验证了该技术方案的可行性，为解决多出口网络中的相关具体问题提供了一条切实可行的途径。

| Abstract: | A design method of control connectivity from local network to multi-ISP is presented on the basis of link track policy and PBR. This disposition plan overcomes the defects of traditional static access that the real time detection and the instantaneous shift of gateway fail to function in case of the failure of an ISP, realizes link backup, effectively loads balancing in multi-entry network, and solves the difficult problems of datacenter network break. The feasibility and practicability of the solution are verified by typical engineering. It provides a practical way to solve connection problems in multi-entry network. |
