针对互联网易拥塞和广播网单向性的缺点,面向大规模信息发布的需求,提出基于融合网络播存机制的数据发布架构。以自适应互补为主要原则,根据文件缺失的程度动态地选择通过广播系统或互联网进行补全,形成数据播发/交互闭环系统。通过仿真与传统数据发布模式进行对比,分析计算该架构数据发布模式的公共信息推送能力,结果表明,该架构在大规模数据发布方面的资源开销较广播系统、互联网系统平均低约两个数量级。
Aimed at easy to congestion of Internet and unidirection of broadcast, faced to the requirement of publish large-scale information, data distribution framework is proposed, which is based on converged network broadcast storage mechanism, by adaptive complementary as the main principle, dynamically through broadcast or the Internet to complement according to the extent of file missing, formed data broadcast/interactive closed loop system. On this basis, through the simulation, compared it with the traditional data distribution model, the delivery ability of commonality information is analyzed and delivery. The result shows that the framework's cost in cosmically data distribution less than broadcast and Internet about two orders of magnitude averagely.
