ECMP等价多路径路由

Equal-cost multi-path routing (ECMP) is a routing strategy where next-hop packet forwarding to a single destination can occur over multiple "best paths" which tie for top place in routing metric calculations. Multi-path routing can be used in conjunction with most routing protocols, because it is a per-hop decision limited to a single router. It can substantially increase bandwidth by load-balancing traffic over multiple paths; however, there may be significant problems in deploying it in practice
等价多路径路由（英文：Equal-cost multi-path routing，缩写 ECMP），是一个在next-hop封包传送到一个单一目的所产生在多个最佳路径并列时的首要路由权重计算路由策略。多路径路由能被应用于首要路由协定同时发生的状况，因为它是一个受限于单一路由的per-hop决策，它有可能借由在多路径负载平衡流量下提供大幅增加的带宽，然而，它可能在实际部署时发生重大问题。
