摘要： 针对目前弹性分组环技术无法组建复杂多环网络，不能透明承载端到端跨环数据业务的问题，提出一种基于通用多协议标签交换 (GMPLS)技术的跨环互连承载模型。该模型通过拓展GMPLS数据平面中的分组交换能力，可实现弹性分组环多环互连和跨环业务承载。仿真结果表明，该模型可行、有效，能透明、可靠地传送跨环数据业务。

Abstract: For the capability of Resilient Packet Ring(RPR) in independently building a large-size and multiple rings network is poor. What’s more, RPR can not transport the edge to edge transparent data services across the rings. This paper presents a span-ring interconnection and carrying model based on expanding the function of GMPLS’s data plane to interconnect and transport the edge to edge data services for multiple resilient packet ring. The simulation result shows that this approach can be used to achieve transparent and reliable transportation of the span-ring services in the RPR multi-ring network.

Key words: Resilient Packet Ring(RPR), GMPLS technology, span-ring interconnection
