在城域网中进行PTN网络建设的模式

Model of Building PTN Network on the Metropolitan Area Network

本文通过对传统城域网采用的SDH组网模式与PTN技术组网比较,论述了PTN组网技术的优势,并结合PTN网络技术的特点,对PTN关键技术加以阐述。针对今后数据业务接入需求的快速增长,提出了一些在城域传输网络中建设PTN网络的模型建议。希望能对城域传输网络的规划设计有所帮助。

By comparing the traditional SDH network model with the PTN and taking the characteristics of PTN model into consideration, the paper has expounded a lot on the key technique of PTN model. Proposal of building PTN on the existing metropolitan area network has been made on the base of the increasing demand of data access. Hope it would help in the process of metropolitan area network planning.
