Article Source: ASPCN Author: Sun Wen Socket transfer Mode Sockets has two main modes of operation: connection-oriented and connectionless. Connection-oriented sockets operations are like a phone call, They have to establish a connection and a call to one person. All things arrive in the same order as they set out. A connectionless sockets operation is like a mail delivery, and there is no guarantee that multiple messages may arrive in the same orde

The address data structure of the socket has different forms depending on the system and the network environment. In order for the different format addresses to be passed into the socket function, the address structure must be forced to be converted to: struct sockaddr{ sa_family_t sa_family;/* address family*/ char sa_data[];/* Variable-length address*/ ... }; The

The simple explanation is:Short connection: Establish a connection, send a packet, close the connectionLong connection: Establish a connection, send a packet, send a heartbeat packet, send a packet, send a heartbeat packet, send a heartbeat packet ...So with frequent data transmission, a short connection creates a TCP connection frequently, and for long connections, the same TCP connection is always usedPackage Com.tree.demo.socket;import Java.io.ioexception;import Java.io.inputstream;import jav

The simple explanation is: Short connection: Establish a connection, send a packet, close the connection Long connection: Establish a connection, send a packet, send a heartbeat packet, send a packet, send a heartbeat packet, send a heartbeat packet ... Therefore, frequent data sending and receiving, the short connection will frequently create a TCP connection, and for long connections, always use the same TCP connection Package com.tree.demo.socket; Import java.io.IOException; Import Java.io

Image Description of the SOCKET protocol The original meaning of socket is "hole" or "socket ". Here we use the 4bds UNIX Process Information mechanism, take the latter meaning. Socket is very similar to a telephone outlet. Take a national-level telephone network as an example. The two sides of a telephone call are equ
