电信运营商OTN与PTN联合组网优化策略研究
|
摘要
在网络技术新时代,电信运营商为了更好地适应全网业务IP化趋势,强化了OTN与PTN联合组网构建,在很大程度上满足了当前发展的实际需求,是技术创新发展的体现。本文分析了OTN与PTN联合组网的模式,并在此基础之上,从设备互联互通、全网时间精确同步、组网保护等方面,具体阐述了OTN与PTN联合组网的问题及优化策略。
In the new era of network technology, in order to better adapt to All IP trend of the whole network business, the telecom operators strengthen the joint network construction of OTN and PTN. To a great extent, it meets the actual needs of the current development and represents the development of technological innovation. In this paper, the mode of OTN and PTN joint networking is analyzed. On this basis, the problems and optimization strategies of OTN and PTN joint networking are elaborated from the aspects of interconnection and intercommunication of equipment, precise synchronization of whole network time, network protection and so on.
