摘　　要：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。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.
