新一代光城域网解决方案——基于RPR的MSR

RPR-based MSR,New Generation Optical MAN Solution

实现多种业务的综合接入与高速传输,完成“三网合一”是城域网的发展趋势。在这个大趋势下,基于弹性分组环(RPR)标准,武汉邮电科学研究院余少华博士代表中国政府提出了多业务环(MSR)光城域网技术并已成为ITU-TX.87标准。多业务环是一种基于分组的多业务传输平台,可以完成高速数据传输和接入各种综合业务,以及在数据链路层实现“三网合一”。详细探讨了基于RPR的MSR的工作机理,包括协议栈和帧结构、节点功能结构、组网应用等几个方面。

The developing trend of MAN includes implementing integrated access and high-speed transmission of multi-service and realizing network convergence. Based on RPR standard Dr. Yu Shaohua of WuHan Research Institute of Posts and Telecommunications on behalf of Chinese government put forward MSR an optical MAN technology which has become ITU-T X.87 standard. MSR is a packet-based multi-service transmission platform which supports high-speed transmission and integrated service access and realizes network convergence on Layer2. This article discusses the working mechanism of RPR-based MSR with protocol stack frame structure node function and networking included.
