react路由的安装: 在要创建项目的目录命令窗里输入: cnpm install -g create-react-app create-react-app  项目名 在创建好的项目目录命令窗里输入: cnpm install react-router-dom --save(此处可以不用--save但是为了方便别人调用你的包时.更快捷的安装好依赖包,我们就得要写了,(cnpm install命令可以自动安装路由依赖文件))       2.根据路径,显示相应的组件 , JSX路由的写法,路由的j…

COMST 2018 主要内容 这是一篇有关快速包转发的综述,先介绍了包转发的有关基础知识和背景,具体介绍了包转发的主流方法,对这些方法进行了细致详尽的比较,最后介绍了最新的方法和未来的研究方向. 包处理包括Fast Path 和Slow Path,前者用于包转发和包头处理,后者主要用于管理.错误控制.维护. 主要的方法有三种:纯软件.纯硬件.软硬结合. 纯软件方法主要在软件层面(零拷贝.批处理.并行性.用户/内核空间)进行性能优化,性能不足的主要是因为网络协议栈架构的不足. 纯硬件方法性能高但…
