具体描述
How prepared are you when it comes to building network-enabled applications? This book provides what every web developer should know about the network - from fundamental limitations that affect performance to major innovations for building even more powerful browser apps. By understanding what the browser can and cannot do, you'll be able to make better design decisions and deliver faster web applications to your users. Author Ilya Grigorik - a developer advocate and web performance engineer at Google - starts with the building blocks of TCP and UDP, and then dives into newer technologies such as HTTP 2.0, WebSockets, and WebRTC. This book explains the benefits of these technologies and helps you determine which ones to use for your next application. Learn how TCP affects the performance of HTTP Understand why mobile networks are slower than wired networks Use best practices to address performance bottlenecks in HTTP Discover how HTTP 2.0 (based on SPDY) will improve networking Learn how to use Server Sent Events (SSE) for push updates, and WebSockets for XMPP chat Explore WebRTC for browser-to-browser applications such as P2P video chat Examine the architecture of a simple app that uses HTTP 2.0, SSE, WebSockets, and WebRTC

##伟大的hpbn!,google网络组出品,免费的在线版在https://hpbn.co/,现在仍在更新!!提供了http2,websocket等业界最新动态,鼎力推荐!!
##学了第1、3部分(剩下两部分暂时没啥学习和使用的需求)。TCP/UDP那两章让我这个网络盲都觉得自己还有救；HTTP/2的bullet point(multiplexing/server push/header compression/stream prioritization)把1.x optimization的不少cons解决了，再次感叹学习计算机就是学习历史。ref1(一个HTTP发展的talk): https://www.youtube.com/watch?v=LSUlhve70UU&t=1594s；ref2(Google Chrome): https://www.igvita.com/posa/high-performance-networking-in-google-chrome
##不光是浏览器，只有是网络相关的，都应该看一下。里面花了重点篇幅讲 HTTP/2。
HTTP/2 的部分已过时。标准变得太快，HPACK 那时候还没有呢，这里也就没写。 在线版有内容更新：http://chimera.labs.oreilly.com/books/1230000000545/index.html
##深刻理解网络延迟，带宽解决不了问题，你不可能超过光速。
