基于3层C/S结构数字电视管理系统研究与开发

Research and Development of Subscriber Management System of Digital TV Based on Three-layer Client/Server Structure

随着数字电视业务推进速度的加快,基于2层C/S模式的传统有线电视用户管理系统中依靠服务器端来处理核心计费业务的压力越来越大,已成为整个系统运行的“瓶颈”,给整个计费账务系统的使用与维护增加了难度,并且这种模式软件的性能、伸缩性及移植性都比较差。针对这些问题,提出基于中间件3层C/S结构的数字电视用户管理系统,有效地解决了传统2层模式与应用需求日益突出的矛盾。

With the advance of digital TV, structure which based on two-layer client/server in the traditional CATV SMS mainly depends on server to deal with the core of accounting service. The pressure of server＇s charge become higher which become the bottleneck of the running system, and enhance difficulty to use and maintenance for accounting management system. The capability, retractility and transplantation of software which based on this structure are not ideal. This paper proposes digital TV SMS based on three-layer Client/ Server structure which settle effectively conflict of two-layer mode with the need of application.
