第七篇：SPDY

12.1 SPDY概念及背景

SPDY 是 Google 开发的基于传输控制协议(TCP)的应用层协议，开发组正在推动SPDY成为正式标准（现为互联网草案）。SPDY协议旨在通过压缩、多路复用和优先级来缩短网页的加载时间和提高安全性。（SPDY是Speedy的昵音，意思是更快）。

为什么需要SPDY？SPDY协议只是在性能上对HTTP做了很大的优化，其核心思想是尽量减少连接个数，而对于HTTP的语义并没有做太大的修改。具体来说是，SPDY使用了HTTP的方法和页眉，但是删除了一些头并重写了HTTP中管理连接和数据转移格式的部分，所以基本上是兼容HTTP的。

Google 在 SPDY 白皮书里表示要向协议栈下面渗透并替换掉传输层协议（TCP），但是因为这样无论是部署起来还是实现起来暂时相当困难，因此Google准备先对应用层协议HTTP进行改进，先在SSL之上增加一个会话层来实现SPDY协议，而HTTP的GET 和 POST 消息格式保持不变，即现有的所有服务端应用均不用做任何修改。因此在目前，SPDY的目的是为了加强HTTP，是对HTTP一个更好的实现和支持。至于未来SPDY得到广泛应用后会不会演一出狸猫换太子，替换掉HTTP并彻底颠覆整个Internet就是Google的事情了。

距离万维网之父蒂姆·伯纳斯-李发明并推动HTTP成为如今互联网最流行的协议已经过去十几年了（现用HTTP 1.1规范也停滞了13年了），随着现在WEB技术的飞速发展尤其是HTML5的不断演进，包括WebSockets协议的出现以及当前网络环境的改变、传输内容的变化，当初的HTTP规范已经逐渐无法满足人们的需要了，HTTP需要进一步发展，因此HTTPbis工作组已经被组建并被授权考虑HTTP 2.0，希望能解决掉目前HTTP所带来的诸多限制。而SPDY正是Google在HTTP即将从1.1跨越到2.0之际推出的试图成为下一代互联网通信的协议，长期以来一直被认为是HTTP 2.0唯一可行选择。

SPDY相比HTTP有如下优点：

1. SPDY多路复用，请求优化；而HTTP单路连接，请求低效

2. SPDY支持服务器推送技术；而HTTP只允许由客户端主动发起请求

3. SPDY压缩了HTTP头信息，节省了传输数据的带宽流量；而HTTP头冗余，同一个会话会反复送头信息

4. SPDY强制使用SSL传输协议，全部请求SSL加密后，信息传输更安全

谷歌表示，引入SPDY协议后，在实验室测试中页面加载速度比原先快64%。

支持SPDY协议的浏览器：

· Google Chrome 19+和Chromium 19+

· Mozilla Firefox 11+，从13开始默认支持

· Opera 12.10+

· Internet Explorer 11+

12.2 本例子流程图

12.3 Netty中使用SPDY

支持SPDY的ChannelPipeline如下图：

不支持SPDY的ChannelPipeline如下图：

例子代码如下：

使用SSL需要使用到SSLContext，下面代买是获取SSLContext对象：
