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

Since I published two articles on the implementation of the Windows Socket communication component, I have received comments from many readers, hoping to share the complete source code. At this time, this seat does not harm you. The complete code of the server component and client component is provided here. In addition, it took a little time to carefully prepare two test cases for readers to learn and understand, one for functional testing (TestEcho)

Synchronizing client Sockets sample The following example program creates a client that is connected to the server. The client is generated with a synchronous socket, so the execution of the client application is suspended until the server returns a response. The application sends a string to the server and then displays the string returned by the server in the console. C# Using System; Using System.Net; Using System.Net.Sockets; Using System.Text;

The socket application scenario, in fast, stable, keeps long connected data transfer codes. HTTP is also encapsulated by the socket, based on the one-time request reply, and then the disconnected socket connection.For example, our common game server, the current very fire of the internet of Things server, all need to open the

First, UNIX Domain Socket IPC The socket API was originally designed for network communications, but later on the socket framework developed an IPC mechanism, is the UNIX Domain socket.
