UDP Packet Size Problem Post from: http://blog.csdn.net/buptzwp/archive/2009/12/22/5055487.aspx During UDP programming, the most common question is how many bytes are sent at a time? Of course, there is no unique answer. The answer is different from the requirements of different systems. Here we only analyze the situation of sending chat messages like ICQ, in other cases, you may be able to get some help

My first blog, in this has been the help of everyone, but also hope that they can learn to pass on to those in need. Recently in doing will vs and MATLAB for real-time transmission of data, mainly using UDP. Why UDP, and the benefits of UDP are no longer in the details here, you want to see the following references to the blog. The following is a separate vs. C #

UDP is the short name of user Datagram protocol,udp, whose main function is to compress the network data traffic into the form of datagram, and provide a simple information delivery service oriented to transaction. Unlike the TCP protocol, the UDP protocol uses the IP protocol to transmit UDP datagram directly, and

numberAll received. For example, the confirmation number is x, that is, the first X-1 data segment received, only when ack=1, the confirmation number is valid, when ack=0, the confirmation number is invalid, this will require retransmission of data, to ensure the integrity of the data.SYN Synchronous serial number, TCP establishes this position 1 when establishing a connectionThe FIN sender completes the send task bit, and when TCP completes the data transfer needs to disconnect, the side that

The contents of this chapter include:1) Overview of UDP2) A simple example of a broadcast applicationSo far, all of the examples we have used are protocol-based protocols, such as TCP, in which we will focus on protocols without connection X (User Datagram Protocol UDP), This protocol is often used in situations where performance requirements are extremely high but allow a small amount of packet lossLet's start with the concept of

One of transport layer learning (transport layer, UDP) transport layer is located between the network layer and the application layer. It aims to support communication between processes running on different hosts. The Transport Layer extends the communication services between different hosts at the network layer to processes running on different hosts. 1. Transport Layer Protocol provides logical communication between applications running on different

A typical function Call of UDP C/sUDP does not have a connection like TCP, the client directly sendto to a server to send data, the server side has been recvfrom blocked to receive any client-sent data.Second, sendto and Recvfrom functionsint sendto (int sockfd, const void* buff, size_t nbytes, int flag, const struct sockaddr* to, socklen_taddrlen); int Recvfro m (int sockfd, void* buff, size_t nbytes, int flag, struct sockaddr* from, socklen_t* Addrl

UDP is short for user‑ramprotocol, which is a User Datagram Protocol. It is mainly used to support network applications that need to transmit data between computers. Network applications in customer/Server mode, including network video conferencing systems, must use UDP protocol. UDP has been used for many years since its publication. Although its initial Glory h

Difference Between TCP and UDP, difference between TCPUDPDifference Between TCP and UDP Difference Between TCP and UDP TCP-the transmission control protocol provides connection-oriented and reliable byte stream services. Before the customer and the server exchange data with each other, a TCP connection must be established between the two parties before data can b

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
