Socket可以看成在两个程序进行通讯连接中的一个端点,一个程序将一段信息写入Socket中,该Socket将这段信息发送给另外一个Socket中,使这段信息能传送到其他程序中。如图1 我们来分析一下图1,Host A上的程序A将一段信息写入Socket中,Socket的内容被Host A的网络管理软件访问,并将这段信息通过Host A的网络接口卡发送...

In the OSI model, TCP fits into the transport layer and IP fits into the network layer. TCP thus sits above IP, which means that the IP header is added onto the higher-level information (such as...doi:10.1007/978-1-349-14772-4_14William BuchananMacmillan Education UK...
If everything goes well, the serveracceptsthe connection. Upon acceptance, the server gets a new socket,clientSocket, bound to the same local port,6666, and also has its remote endpoint set to the address and port of the client. At this point, the newSocketobject puts the server in direc...
The context eventually creates end objects (SSLSocket and SSLEngine) which actually implement the SSL/TLS protocol. SSLContexts are initialized with two callback classes, KeyManager and TrustManager, which allow applications to first select authentication material to send and second to verify ...
总而言之:Socket是应用层与TCP/IP协议族通信的中间软件抽象层。 Socket是应用层与TCP/IP协议族通信的中间软件抽象层 图片来源:socket图解 · Go语言中文文档 (topgoer.com) 阻塞式IO模型 在《UNIX Network Programming》 一书当中,用UDP传输的案例模拟了阻塞式的IO模型,这个模型的概念和Java BIO的阻塞模型类似。
