The communication model of socket communication in linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Guidance: 1. Socket Introduction Socket is a TCP/IP network API that can be used to

What is the difference between synchronous IO and asynchronous Io, what is blocking IO and non-blocking IO respectively? The answers given by different people in different contexts are different. So first limit the context of this

Some processes require the ability to inform the kernel beforehand, so that once the kernel discovers that one or more of the I/O conditions specified by the process are ready (that is, the input is ready to be read, or the descriptor is able to

5 Types of IO models and differences available to UNIX:1. Blocking IO2. Non-blocking IO3.IO multiplexing (SELECT and poll)4. Signal-driven IO (SIGIO)5. Asynchronous IO (POSIX aio_ series functions)Ii. 1. Blocking IO Model:The most popular IO model

ObjectiveBefore analyzing the I/O model, first understand the basic concepts of synchronous I/O and asynchronous I/O: synchronous I/O: When a process invokes an I/O operation function, the process is suspended (that is, blocked) until the I/

Welcome reprint, Reproduced please specify the original address: http://blog.csdn.net/majianfei1023/article/details/453148030. IntroductionAre blocking not synchronous, non-blocking is not asynchronous, what is their relationship? Students who have

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

Linux programming-udp socket full strategy, udpsocket This article will summarize important knowledge points of udp socket programming in linux. This article will cover both developers and some remote knowledge points of udp socket. Do as much as

Network Programming: synchronous, asynchronous, blocking, non-blocking, and network programming I. Network Programming I/O models always involve these concepts. I have asked a lot of people, but few of them can clearly tell the difference between

Finally solved yesterday... 1. Background: As the number of users increases, UDP packet loss increases. In fact, the packet volume is not large. UDP packets of no more than packets per second during peak periods should not be lost. The previous

A recent example is done with the RTSP protocol. The server has already, just need to do the client to do the line, in the process of the discovery of a number of problems, is about the UDP client binding problem.Perhaps everyone in the book to see

Netty Series (i) Linux network IO Model I. BASIC conceptBefore formally starting the Linux IO model, let's introduce 5 basic concepts.1.1 User space and kernel spaceNow that the operating system is using virtual memory, the 32-bit operating system,

Kernel version: 2.6.34 UDP packet ReceptionThe reception of UDP message can be divided into two parts: the protocol stack receives the UDP message, inserts the corresponding queue; the user calls Recvfrom () or recv () system call to take out the

Blocking: When a user process accesses data, if IO is not completed, wait for IO to complete or make a system call to determine whether IO is completeNon-blocking: When a user process accesses data, it returns a status value immediately, whether or
