泰达网络OTN传输网络工程实践

An Engineering Practice of OTN in TEDA Cable TV Network

随着互联网技术的飞速发展,网络中的主要流量由图片、文本业务变成视频及数据传输业务,以往的传输网络已经不能满足业务大量增长的需求。OTN具有大颗粒带宽、多种信号封装及多通道传输等技术优势,OTN技术的发展和使用解决了大带宽的传输需要。介绍了OTN的技术和功能特性,结合泰达有线电视网络公司网络工程项目,列出了OTN网络的拓扑图及设备配置,最后展望了OTN技术未来的方向。

With the rapid development of Internet technology,main network traffic changed from text and image services to video and bulk data transfer services,and former transport network can not satisfy the requirement of wide-bandwidth any more.This subject has been solved by the development and the use of OTN technology.OTN has the advantages of large particle bandwidth,multiple signal encapsulation and multi-channel transmission.This paper introduces both technical and functional characteristics of OTN.With the description of the OTN engineering practice in TEDA Cable TV Network Co.,Ltd,the article gives the topology model and configuration list.In the end,future development directions of OTN technology were prospected.
