Overview
这个框架用来创建网络连接，使用传输和加密协议 来发送和接收数据。
使用这个框架，你可以为你自定义的应用协议 直接访问 TLS, TCP, and UDP 协议。
NSURLSession 也是基于这个框架来实现加载 HTTP- 和基于URL的资源，
Topics
1、Essentials
A local or remote endpoint in a network connection.
An object that stores the protocols to use for connections, options for sending data, and network path constraints.
2、Connections and Listeners
Implementing netcat with Network Framework
Build a simple netcat tool that establishes network connections and transfers data.
A bidirectional data connection between a local endpoint and a remote endpoint.
An object you use to listen for incoming network connections.
An object you use to browse for available network services.
An object you use to send and receive custom Ethernet frames.
3、Network Protocols
Configure protocol options to use with connections and listeners, and inspect the results of protocol handshakes.
Configure options for connections that use the Transmission Control Protocol.
Configure options for connections that use Transport Layer Security.
