多媒体传输平台在电信运营商网络中的部署和应用

Multimedia Transmission Platform Deployment and Application in Telecom Operator Networks

随着新兴互联网媒体的兴起,高清与超高清时代的到来,以及IP化和接入方式的技术进步,图像业务市场根据视频质量的不同而趋于分化。传统的卫星传送等方式已不能满足高质量、高清晰度的大带宽要求,现有传统运营商网络已不能满足传统和新兴媒体用户对大带宽、高清信号灵活传输的需求,迫切需要一张高质量、大带宽视频传输网络,可提供给用户定制化的视频传送服务,按照使用时间和带宽进行灵活计费,同时,提高电路带宽的利用率,实现用户和运营商的双赢。中国联通于2016年计划建设一张多媒体传输专网,2017年正式开工,截至2018年3月已完成大部分节点的硬件和网管建设工程,个别节点已提前完成竣工验收并投入使用。笔者将重点针对中国联通多媒体平台的组网和应用进行研究。

With the rise of emerging Internet media,the advent of high-definition and ultra-high-definition eras,and technological advancements in IP and access methods,the image service market tends to be differentiated based on the quality of video.Traditional satellite transmission and other methods can no longer meet the high-bandwidth requirements of high-quality,high-definition,the existing traditional operator networks can no longer meet the needs of traditional and emerging media users for flexible transmission of large bandwidth,high-definition signals,an urgent need for a high quality and large-bandwidth video transmission networks can provide customized video delivery services for users,flexibly charge according to usage time and bandwidth,increase the utilization of circuit bandwidth,and achieve a win-win situation for users and operators.China Unicom plans to build a multimedia transmission private network in 2016 and formally start construction in 2017.By the end of March 2018,the company has completed the construction of hardware and network management of most nodes.Individual nodes have completed acceptance and put into use in advance.The author will focus on the research and development of the network and application of China Unicom's multimedia platform.
