摘要
由于电力通信传输网承载的业务类型开始由低速率、小颗粒的TDM业务转向高速率、大颗粒的IP业务,传统的SDH/MSTP技术已经无法满足需求,提出PTN技术,在介绍PTN技术原理的基础上,分析PTN的优势,结合PTN关键技术机制重点阐述PTN网络上承载的电力系统中各项关键业务,并介绍了应用情况及效果。
Currently the business type of power communication transmission network is transmitting from low rate TI）M busi ness with small particles to high speed IP business with large particles. Traditional SDH/MSTP technology can not satisfy the practical requirement anymore. The PTN technology Is proposed to satisfy such practical requirement, through introducing the principle of PTN, the advantages of PTN are analyzed. This paper focuses on the key business of power system on PTN ae cording to critical mechanism of P＇FN. The application of this technology is represented and the performance is also discussed.
