| 摘 要： | 弹性分组环(RPR)是一个标准环网，采用光交叉连接(OXC)节点连接多个RPR标准网，构建RPR多环互连网络，该多环网的帧分为标。住帧和跨环帧，其中标准帧在RPR标准网内传输，跨环帧在不同RPR标准网间传输。分析了交叉连接节点的MAC结构，提出了RPR多环互连网络的跨环转发算法。仿真结果表明设计的算法可以保证跨环帧的收发是稳定可靠的。

| Abstract: | To establish interconnected resilient packet rings, a new node (named RPRX node)is introduced to interconnect multi-RPR networks. The frame format includes standard frame and span-ring frame. The standard frame is transmitted in a standard RPR networks, then span-ring frame is transmitted from one ring to another. The span-ring transmission algorithm is proposed based on the analysis of the MAC structure of RPRX node. The simulation results show that the algorithm can guarantee a steady and reliable transmission of the span-ring frame. |
