HTTP2.0 is coming. You don't even know what SPDY is?

In the cloud computing era, browsers and mobile apps have become the main portals for cloud resources. HTTP1.1 has become the bottleneck of this ecological environment. SPDY is a TCP-based application layer protocol developed by Google. It is designed to replace the current HTTP1.1. It is said that the performance of the SPDY protocol is twice faster than that of HTTP1.1. SPDY retains the meaning of HTTP1.1, but in the transmission mode

In the cloud computing era, browsers and mobile apps have become the main portals for cloud resources.

HTTP 1.1 has become the bottleneck of this ecological environment.

SPDY is a TCP-based application layer protocol developed by Google. It is designed to replace the current HTTP 1.1 protocol.

It is said that the performance of SPDY protocol is 1 times faster than HTTP 1.1.

SPDY retains the semantics of HTTP 1.1, but the transmission method is different from HTTP 1.1. That is to say, existing Web applications can be migrated from HTTP 1.1 to SPDY without any modification.

The SPDY protocol and HTTP 1.1 are both based on TCP, but they differ from HTTP 1.1 in that HTTP 1.1 and TCP are tightly coupled, HTTP 1.1 messages are directly sent through the TCP packet. The SPDY Protocol defines a framing layer over TCP, which can also be called an HTTP Layer.

The connection of the framing layer is called stream, which is different from the connection of TCP. Each connection corresponds to multiple streams. Each stream corresponds to a request/response. Multiple Streams can send and receive data in parallel.

HTTP 2.0 is said to be officially Release this year. SPDY is a reference of the HTTP 2.0 standard.

I want to know what problems does the SPDY protocol solve with HTTP 1.1? See http://www.slideshare.net/ihower/a-brief-introduction-to-spdy-http20
