Socket connectionsA socket is a communication machine. By virtue of such a mechanism. The development of the customer/server system can be done on a local machine. Can also boast the network.There is a difference between the creation and use of sockets and pipelines. Because the socket clearly separates the client from the server.Socket connections:First, the ser

Log4j2 test instance-socket centralized print example, log4j2-socket1. Background Because the company recently set up a centralized log management platform and required that all system logs be sent to the unified platform, based on this, we studied the socket of log4j2. 2. Prepare materials Two jar packages for log4j2: log4j-api-2.1.jar and log4j-core-2.1.jar. (The version must be consistent, especially the

How to Implement Socket heartbeat packets and socket heartbeat packets A client has been created recently, but a disconnection detection function is required. Let's take a look at using the custom HeartBeat method to check the client connection. How to Implement heartbeat packets: After the client is connected to the server, the server maintains an online client list. The client sends a heartbeat packet to

For TCP/IP, UDP, socket programming These words you are not very strange, right? With the development of network technology, these words are filled with our ears. Then I would like to ask: 1. What is TCP/IP, UDP?Where is the 2.Socket?What's 3.Socket?4. Will you use them? What is TCP/IP, UDP? TCP/IP (Transmission Control protocol/internet Protocol), the Transmi

be timely access to services. two, two types of transport protocol: TCP;UDP TCPIstranfer Control ProtocolShort, is a connection-oriented protocol to ensure reliable transmission. Through the TCP protocol transmission, obtains is a sequential error-free data stream. A connection must be established between the pair of two sockets of the sender and receiver to communicate on the basis of the TCP protocol, and when one socket (usually the server

DotNet. Net. MySocket isSLB. NET(Server Load Balance Server Load balancer) is a core component of the project. Therefore, we have been wondering whether multiple processes can provide one service, like the IIS Web garden, to work together with client requests. However, if you use the socket component of the. net framework, it seems that multi-process sharing cannot be achieved. So I had my own idea. Below is a demo program I wrote (download at th

In actual projects, it is found that the single-process server has limited capacity to process highly concurrent customer requests.

Member name Description Dgram Supported by the. NET Framework Lite version. Supports datagram, that is, the maximum length of a fixed (usually very small) connectionless and unreliable message. Messages may be lost or duplicated and may not be arranged in order when they arrive.DgramA Socket type does not require any connection before sending or receiving data, and can communicate with multiple hosts.DgramUse the datagram protocol (Udp)

Socket Transmission ModeSocketsThere are two main operations: connection-oriented and connectionless. connection-oriented sockets operations are like a phone. They must establish a connection and a person call. the order of all things at arrival is the same as that at their departure. the connectionless sockets operation is like a mail delivery, with no guarantee. The order of arrival of multiple mails may be different from that of departure.Which mod

Encapsulation and encapsulation. The class of. NET is encapsulated at one time, and certainly the scalability is not so good. However, components are easy to use. So I don't care much about it. This encapsulated TCP component is encapsulated by the socket component of Delphi. It simply provides three attributes and three events. There are only a few public functions. The convenience of this component is that when one end is connected or disconnected,

The socket is one end of two-way communication between two programs running on the network, it can accept the request, also can send the request, can use it to write the data on the network more conveniently. In Java, there is a special socket class to handle the user's request and response. Using the method of the socket class, you can realize communication betw

PHP socket programming is more difficult to understand things, but, as long as we understand the relationship between several functions of the socket, and the role they play, then it should not be difficult to understand, in my opinion, socket programming, in fact, is to establish a Network service client and server , this is the same as the client and server sid
