一种改进的多媒体信息发布系统框架

借鉴P2P的思想，提出了一种以代理节点为中心的A2P（Agent-to-Player）框架，由服务器、管理端、场馆代理端和播放终端等四部分组成，以场馆代理端为中心对播放终端进行分组管理，并改进了终端分组和文件下载算法，降低了系统管理的复杂度，提高文件的扩散速度；任务编排功能采用模板来管理，并且通过B／S模式发布，增加了任务管理和播放的灵活性．基于该框架设计了多媒体信息发布系统，取得了良好的效果．

Advanced Multimedia Information Display System Architecture

An A2P architecture centered on venue agent was proposed. It consisted of server, management terminal, venue agent and player terminal. The network nodes were organized into several groups by venue agents. The algorithms of both grouping and downloading were proposed to reduce the complexity of system management, at the same time, it improved the speed of spreading files. The function of scheduling task was managed by template, and released in B/S mode which can increase their flexibility. Based on the architecture, the multimedia information display system was designed and achieved good results.
