OTN和PTN的联合组网研究

The study on the networking of optical transport network and packet transport network

在对光传送网(OTN)和分组传输网(PTN)进行分析的基础上,提出了OTN和PTN联合组网的问题,讨论了OTN和PTN的联合组网方案,着重研究了PTN业务在大带宽OTN通道中如何传送的问题,即PTN业务如何适配到OTN网络中。最后,对OTN和PTN联合组网的发展趋势进行了展望。

Based on the analysis of OTN （Optical Transport Network） and PTN （packet transport network）, the paper study the problem of joint networking with OTN and PTN. The paper discusses the networking scheme of OTN and PTN, and put an emphasis on how to arrange the traffic of PTN into the communication channels of OTN. That is, how to make an adaptation between the different traffic granularities of PTN and OTN. Finally, the paper gives a prediction about the development trend of OTN and PTN.
