摘要
分组增强型OTN技术主要面向满足城域范围内带宽大幅增长和多业务承载的需求,更适于城域网内分组化、宽带化、扁平化和综合化的发展方向。首先给出了分组增强型光传送网的技术原理和系统架构,简要介绍了当前的标准化和研发进展,并针对IPMAN扁平化、大客户专线承载、C-RAN承载等分组增强型光传送网的典型应用场景进行了详细研究,包括业务需求、承载模式和网络架构等方面的分析,探讨了可能的引入策略和解决方案。
Packet enhanced OTN technology is mainly to meet the substantial bandwidth growth and multi-service providing, which is a better choice in a packet-based, broadband-based, flat and integrated MAN. It gives the fundamental principles and system architecture of POTN, describes briefly the standardization and research progress. It discusses typical application scenarios of POTN in the MAN, such as flat IPMAN, leased-line service and C-RAN carrying, analyzes service demanding, carrying models,and network architecture, proposes the possible introducing scheme and resolution.
