摘　　要：弹性分组环技术是一种优化的、用于光纤环型拓扑的、并具有强壮和高效特点的技术。弹性分组环网能够承载多种业务,包括对抖动和时延敏感的如话音和视频流量、以太网和IP业务等。该文提出了报文RPR(Resilient Packet Rings)环网的选路表方法及设计方案,该方法成功地解决了数以10万计路由表项的更新、复杂RPR拓扑库的震荡、高成本硬件存储空间和CPU开销的难题。Resilient packet ring （RPR） technology is optimized for robust and efficient packet networking over a fiber ring topology. RPR networks have the ability to carry multiple services, including jitter-and latency-sensitive traffic such as voice and video in addition to Ethernet and Interact protocol （IP） services. This paper presents the routing method of the packet going to the RPR ring network and its design. It is succeeded to resolve the updating of tens of thousands of routing table, the shaking of complex RPR topology database, high cost of hardware storage space and the spending problem of CPU.
