What are the applicable scenarios for UDP?
UDP is applicable to scenarios that emphasize output performance rather than completeness, such as audio and multimedia applications.
UDP applicable scenarios:
The UDP protocol is sent directly and does not determine whether to receive or send. Success, application scenario: When output performance is emphasized rather than completeness, such as audio and multimedia applications.
UDP communication protocol
No connection;
UDP uses best effort delivery, no To ensure reliability, UDP is packet-oriented. UDP neither merges nor splits the packets delivered by the application layer, but retains the boundaries of the packets;
Application No matter how long the message is handed to UDP by the layer, UDP will still send it, that is, send one message at a time;
UDP has no congestion control;
UDP supports one-to-one, one-to-many, many-to-one and many-to-many interactive communication.
-
UDP header overhead is small, only 8 bytes.

How to implement asynchronous communication using PHP and UDP protocols
Jul 30, 2023 pm 07:31 PM
How to use PHP and UDP protocols to implement asynchronous communication In modern Internet applications, asynchronous communication has become a very important method. By using asynchronous communication, user requests can be processed concurrently without blocking the main thread, improving system performance and response speed. As a popular back-end programming language, PHP how to use UDP protocol to achieve asynchronous communication? This article will introduce how to use the UDP protocol in PHP to implement simple asynchronous communication, and attach specific code examples. 1. Introduction to UDP protocolU
What are the UDP port numbers?
Feb 23, 2023 pm 02:00 PM
Common UDP port numbers are 53, 69, 161, 2049, 68, and 520. UDP uses port numbers to reserve their own data transmission channels for different applications: 1. Network File System (NFS), the port number is 2049; 2. Simple Network Management Protocol (SNMP), the port number is 161; 3. Domain Name System (DNS) , the port number is 53; 4. Simple File Transfer System (TFTP), the port number is 69; 5. Dynamic Host Configuration Protocol (DHCP), the port number is 68; 6. Routing Information Protocol, the port number is 520, etc.
How does Java network programming use UDP for connectionless communication?
Apr 15, 2024 pm 12:51 PM
UDP (User Datagram Protocol) is a lightweight connectionless network protocol commonly used in time-sensitive applications. It allows applications to send and receive data without establishing a TCP connection. Sample Java code can be used to create a UDP server and client, with the server listening for incoming datagrams and responding, and the client sending messages and receiving responses. This code can be used to build real-world use cases such as chat applications or data collection systems.
What transport services does udp provide?
Feb 27, 2023 am 10:20 AM
UDP provides "connectionless" transport services. The Chinese name of UDP is User Datagram Protocol. It is a connectionless transport layer protocol in the OSI reference model. It provides simple and unreliable transaction-oriented information transmission services; UDP provides applications with a way to send encapsulated data without establishing a connection. IP packet method.
How to analyze UDP protocol
May 12, 2023 pm 02:49 PM
1. Socket: socket: ip address + port number. In the TCP/IP protocol, it uniquely identifies a process in network communication. Sockets are used to describe a one-to-one relationship between network connections. The TCP/IP protocol stipulates that network data flow should use big-endian byte order, that is, (memory) low address high byte (data). 2. UDP_SOCKET related UDP protocol----User Datagram Protocol (non-connection oriented)---SOCK_DGRAMh represents host, n represents network, l represents 32-bit long integer, and s represents 16-bit short integer. The IPv4 address format is defined in netinet/in.h, IPv4 address: sockadd
How to implement UDP programming for network communication based on UDP protocol in Java
May 17, 2023 pm 01:13 PM
Basic introduction to UDP programming communication classes DatagramSocket and DatagramPacket [data packet/datagram] implement network programs based on the UDP protocol. UDP datagrams are sent and received through the datagram socket DatagramSocket. The system does not guarantee that the UDP datagram will be safely delivered to the destination, nor is it sure when it will arrive. The DatagramPacket object encapsulates a UDP datagram, which contains the IP address and port number of the sender and the IP address and port number of the receiver. Each datagram in the UDP protocol gives complete address information, so there is no need to establish a connection between the sender and the receiver. The two classes/objects at the core of the basic process Da
What does UDP protocol mean?
Aug 08, 2023 pm 03:43 PM
UDP is a connectionless transport layer protocol that provides a way to send data packets to the network, but does not guarantee the reliability, sequence and integrity of data packets, nor does it provide congestion control and flow control, etc. Function. Characteristics of UDP: 1. No connectivity, no need to establish a connection before sending data, data packets can be sent directly to the target host; 2. High efficiency, the header overhead is small, only 8 bytes; 3. Unreliability, It does not provide the reliability of data packets. After the data packet is sent, it will not be resent even if it is lost, nor does it guarantee the order of the data packets, etc.
Detailed explanation of why DNS uses UDP instead of TCP!
Mar 01, 2024 pm 08:16 PM
The main reason why DNS (DomainNameSystem) uses UDP (UserDatagramProtocol) instead of TCP (TransmissionControlProtocol) is for performance and efficiency considerations. The following explains in detail why DNS chooses to use the UDP protocol: Small requests and fast responses: DNS queries are usually small requests, requiring only a few bytes of data transfer. UDP is a connectionless protocol that does not require establishing a connection before communicating, but instead sends packets to the destination address and waits for a response. This makes UDP more suitable for fast response scenarios than TCP. Low latency: DNS queries generally require low latency to provide fast domain name resolution services.
