基于SDN的超高清播总控系统IP矩阵建设与应用

Construction and Application of IP Matrix for Ultra High Definition Broadcast Control System Based on SDN

为了满足超高清频道的发展和需求,西安广播电视台新建了超高清播总控系统网际协议(Internet Protocol,IP)矩阵。系统采用多脊多叶的网络架构,以软件定义网络(Software Defined Network,SDN)为技术基础,从安全性控制、逻辑矩阵规划、调度路径部署以及安全性考虑几个方面进行设计与应用,满足融合媒体一体化调度需求,实现无阻塞调度以及系统后期持续无缝扩展。详细介绍该系统的建设和应用情况,为相关单位建设同类系统提供参考。

In order to meet the development and demand of ultra high definition channels,Xi'an radio and television station has built a new ultra high definition broadcast control system Internet Protocol(IP)matrix.Based on Software Defined Network(SDN)technology,the system is designed and applied from the aspects of security control,logical matrix planning,scheduling path deployment and security considerations to meet the requirements of integrated media scheduling,achieving non-blocking scheduling and continuous seamless expansion in the later stage of the system.This paper introduces the construction and application of the system in detail,and provides reference for related units to build similar systems.
