This article will cover both developers and some remote knowledge points of udp socket. Do as much as possible. After reading an article, you will have a comprehensive understanding of

TCP/IP is a commonly used standard protocol for network interconnection. It can communicate with each other in different environments and nodes, it is the protocol used by all computers connected to the Internet to exchange and transmit various information over the network. It is also the protocol used for interconnection between Windows NT, Windows 2000 Server, NetWare and UNIX. TCP/IP is actually a hierarchical protocol. It contains many other protocols and forms a TCP/IP protocol group. The P

Figure 1 shows the interface for setting rules for the firewall software of Rising's Personal Edition. Careful readers will find that the "protocol" column in Figure 1 contains "TCP", "UDP" and other terms. What do they mean? Now let's talk about TCP and UDP. We have learned what is "data packet ". Understanding data packets is of vital significance for network security in network management. For example, t

The difference between TCP and UDP is described below:1. Connection-based and connectionless2. Requirements on system resources (more TCP and less UDP)3. UDPProgramSimple Structure4. Stream mode and datagram Mode5. TCP ensures data correctness, UDP may cause packet loss, and TCP ensures data sequence. UDP does not guar

UDP: User Datagram UDP is a simple datagram-oriented transport layer protocol. Each output operation of a process usually generates a UDP datagram and assembles it into an IP datagram to be sent. This is different from the stream-oriented protocol, such as TCP. The data generated by an application is not directly associated with a single IP datagram.

1. UDP protocol: The User Data Protocol (UDP) is a "User Datagram Protocol". It is a connectionless protocol, which is mainly compared with the TCP protocol. We know that when using the TCP protocol to transmit data, we must first establish a connection (that is, a handshake) to transmit data. When a computer uses the UDP protocol for data transmission, the sen

Have time to go to the forum, found that the discussion UDP reliable transmission and heat up, some people think that UDP high efficiency, some people think that UDP packet retransmission mechanism is easy to control, there are friends to limit the test, of course, some people sell their own things, here to write a bit of my personal opinion.UDP reliable transmis

1. What are TCP and UDP?TCP and UDP are two transport layer protocols in the TCP/IP protocol. They use the IP routing function to send data packets to the destination for the ApplicationProgramAnd the application layer protocol (including HTTP, SMTP, SNMP, FTP, and telnet) to provide network services. TCP provides connection-oriented and reliable data stream transmission, while

Before we begin, we'll use a diagram to explain the process of receiving a network message from a Linux system. First of all, network packets sent through the physical network to the NIC driver will read the message in the network into the ring buf
