有线数字广播电视前端硬件冗余模式机理初探

The Discussion on the Mechanism of Devices Redundancy of CATV Headend

论述在有线数字广播电视前端系统设计过程中,以冗余技术保障前端高可靠性的必要性及选择合理冗余模式的重要意义,通过对旁联冗余系统数学模型进行计算机仿真,对旁联冗余模式进行定量分析,实现系统最佳效能参数的优选。

The paper study the importance about the necessity to increase reliability for CATV headend by redundant means during the system de- sign of headend,the author adopting the method of quantitative analysis for standby redundancy system by mathematical modelling and computer emulating,to achieve optimal system performance parameters.
