This function provides an iterative server, rather than providing a concurrent server as a TCP server. There is no call to fork, so a single server process has to deal with all customers. In general, most TCP servers are concurrent, and most UDP servers are iterations. For this socket, a queued occurrence is implied in the UDP layer. In fact, each UDP socket has

When your data scale reaches the Pb level, it will be time-consuming and labor-consuming to move such large data volumes, this is also one of the biggest challenges enterprises face when taking advantage of AWS's scale and elasticity to process analysis tasks. This article mainly introduces the accelerated File Transfer Protocol and describes how to use tsunami DUP to migrate large-scale data to the cloud, where UDP is used to process data transmissio

In the network communication protocol, the UDP protocol, which is equally important to TCP, is described briefly today. We often see this protocol in some network firewalls or anti-virus software. So what is the specific meaning of this protocol? UDP protocol User Data Protocol (UDP) is also a communication Protocol on the OSI transport layer. However,

In my two blog posts, a simple introduction and implementation of UDP (TCP)-based Windows (Unix process basically consistent) under the server and client programs, this article continues to explore some of the details of UDP programming.http://blog.csdn.net/nk_test/article/details/47733307http://blog.csdn.net/nk_test/article/details/47756381is a simple UDP client

Basic differences between TCP and UDP1. Connection-based and no-connection2.TCP requires more system resources, less

Reproduced from: http://blog.chinaunix.net/uid-20180960-id-2998594.html, thank the author. When it comes to UDP programming, the easiest question we can think about is how many bytes are sent at a time? Of course, this does not have the only answer, compared to different systems, different requirements, the answer is not the same, here just like the ICQ type of sending chat messages to analyze, for other cases, may also get a little help:First, we kn

Java UDP Socket programming and javaudpsocket ProgrammingUDP protocol The services provided by UDP protocol are different from the end-to-end services provided by TCP protocol. It is non-connection oriented and is an unreliable protocol. UDP sockets do not need to be connected before use. In fact, UDP implements two fu

ObjectiveThe TCP protocol provides a reliable communication channel in an unreliable network environment, hiding a lot of underlying details and making the application more concise. However, some applications do not require this high level of reliability, do not require sequential delivery, and TCP increases latency for increased reliability, which is not applicable in some scenarios where latency or jitter requirements are high. For this reason, UDP

After the standard UDP client has opened a set of interfaces, it generally uses the sendto and recvfrom functions to send data. Recently, we can see that the ntpclient Code uses the direct method of the send function, so we have analyzed it, in the past, UDP sent data in two ways for you to choose from, by the way, UDP connect usage will be clearly explained.Meth

For UDP protocol, it is different from TCP protocol in the transport layer, and its length is very suitable for the sharding policy. All of these content will be clearly explained in the article. So let's take a look at the specific content, hoping to provide you with a useful reference. 1. Brief Introduction to UDP UDP is a transport layer protocol, which is in

TCP-IP learning notes of UDP (User Datagram Protocol) I. Introduction UDP is a simple datagram-oriented transport layer protocol: Each output operation of the process generates a UDP datagram, and assembled into an IP datagram to be sent. This is different from the stream-oriented character protocol, such as TCP. The full data generated by the application may be

1.UDP Brief IntroductionUDP is a transport layer protocol, and the TCP protocol is in a hierarchy, but unlike the TCP protocol, the UDP protocol does not provide time-out retransmission, error retransmission and other functions, that is, it is unreliable protocol.UDP Datagram Structure:UDP header Format:Explain: Source port number: The item is any option, the default value is 0, which can be

In the previous article Go Socket programming Practice: TCP Server and client implementation, we implemented an echo server, and also implemented a client to access the server.This article explains how to implement a UDP server and client.The protocol we're using this time is RFC 868,This protocol provides a site-independent, machine-readable date and time information.

destination process) is done by TCP.7, the transport layer of the main protocolThe two main protocols of the TCP/IP transport layer are important standards for the Internet, TCP (Transmission Control Protocol) [RFC 768], User Datagram Protocol UDP (subscriber Datagram Protocol) [RFC 793].The data flow of the transport layer is to establish a logical connection between the network endpoints. If you use UDP,

bytes.Calculation principle of 1.3 UDP checksumThe UDP checksum is basically consistent with the TCP checksum.UDP checksum needs to divide the IP pseudo header, UDP header, UDP data into 16-bit words, and then accumulate (if the total length is an odd number of bytes, then add a bit to 0 bytes at the end), and finally

Guidance Remember to go to college in the "Computer Network Foundation" specialized class, at that time is really pure kind ignorance, think I later do not engage in network this piece of things, do not need to study computer network This course, as long as the exam pass on the line. But after work I found that whether we do software development, will be more or less contact with the computer network, because th

UDP can be used in many aspects. So what we will introduce to you today is the process of implementing UDP using the WinSock API. First, let's take a look at the basic definition. User Data Protocol (UDP) is a Protocol used to define computer communication for Packet Exchange in an interconnected network environment. It is one of the widely used communication pro

Transport layer: UDP Protocol I, Transport Layer protocolFrom the network layer protocol described earlier, the two ends of the communication are both hosts, the IP datagram header indicates the IP address of the two hosts. But from the transport layer, it is a process in the sender host that is exchanging data with a process in the receiving host, so strictly speaking, the communication parties are not the hosts, but the processes in the host. The

The Transport layer provides communication services to the application layer above it, which belongs to the highest level of the communication section and is also the bottom of the user's function. Two hosts are actually communicating with each other in a two host application process . Communication between application processes is also known as end-to-end communication . The messages of different processes in the application layer are delivered down to the transport layer through different
