Mechanism of iBGP single best path propagation may prevent the router from acquiring diverse paths,which results in connection disruption and inter-domain churn in the scene of transient link.MP-RCP optimises the route control platform (RCP)to reduce the session numbers and configuration complexity,makes use of global visible routes to compute and disseminate multiple paths for each router.When a router detects the failure in best path,the router encapsulates the packets and forwards them to the backup path to avoid the connection disruption.MP-RCP also separates the failure detection and processing in order to prevent the frequent convergence triggered by transient failures,which reduces the inter-domain disturbance.It is proved through Abilene topology and the experiment of topology generation that the MP-RCP structure reduces the forwarding disruption and inter-domain churn effectively.%iBGP 传播单条最佳路径机制不能保证路由器获得多样性路径，造成链路瞬时故障场景下连接中断及域间扰动。MP-RCP（MultiPath Route Control Platform）优化路由控制平台RCP以降低会话数量及配置复杂性，利用全局可视路由对每台路由器计算、分发多路径。当路由器检测到最佳路径失效后，将报文封装转发到备份路径中避免连接中断；MP-RCP中将失效检测、处理进行分离以避免瞬时故障引起的频繁收敛，从而降低了域间扰动。通过使用Abilene拓扑以及生成拓扑的实验证明了MP-RCP结构能有效避免转发中断和域间扰动。
