## p2p缓存系统 ## 基于Golang的Aop设计模式 龚浩华 QQ 29185807 月牙寂 ## 背景 Web缓存（类似CDN技术） ☑ 网页、图片 普通下载 ■ 普通视频 P2P缓存 下载（bt等） ■ 视频（qvod、百度影音等） ## 背景 P2P缓存好处 ■ 一次获取，多次利用 ■ 减少局域网出网流量 ■ 提升用户体验 ## 背景 P2P缓存服务器（基于c++开发） 有属性（成员变量）、有行为（成员函数） 没有可以独立执行的机制 ■ 有属性（成员变量）、有行为（成员函数） 还有独立执行的活动（有自己独立的线程） ■ 有属性（成员变量）、有行为（成员函数） 借助其他线程运行 ## AOP AOP （agent-oriented programming） Agent: 智能体、职能代理。源于分布式人工智能（DAI） 1、自主的、智能的 2、具有社会性（与环境通信） 3、反应能力，理解环境并对环境刺激做出适应的反应
