数据分发软件设计方法

Research of software design methods in data dissemination

数据分发是基于IP多播或广播技术的一种新的主动服务模式,能够广泛的应用于局域 网、广域网和数字广播网络,其目的是将热点信息推送到海量的用户终端中。归纳了数据分发的服务 特点和传输特性,提出了用于解决数据传输误码的重传因子概念并给出了量化计算方法,最后讨论了 基于IP广播发送和IP多播技术的数据分发发送、接收算法与实现过程。

Data dissemination is a novel active service architecture based on the IP multicasting or IP broadcasting technology. It can be widely applied in LAN,WAN and digital broadcasting network,and transmits the hot-information to massive consumers. The services and transmission characteristic of data dissemination was concluded,re-transmission ratio and computing methods which can improve the errors of communication channels was submited.The sending and receiving algorithms and implementation codes for data dissemination were discussed.
