For each TCP socket, there is a send buffer and receive buffer corresponding to it, here is an example of the sending buffer, accept buffer, the relationship between the sliding window protocol. One, recv end In the listening socket on the

First, Function introductionThe Netperf is a test tool for network performance , primarily based on TCP or UDP transmissions. Depending on the application, performance testing can be performed for bulk data transfer (bulk data transfer) mode and

UDP and TCPUDP (User Datagram Protocol, Subscriber Datagram Protocol) is a no-connection protocol that does not guarantee that the UDP datagram will reach its final destination, does not guarantee that the order of the datagrams remains unchanged

TCP Output Each TCP socket has a send buffer, and we can use the SO_SNDBUF socket option to change the size of the buffer. When a process calls write, the kernel copies all data from the application's buffer (either the application's buffer is

http://www.ibm.com/developerworks/cn/linux/l-netperf/ When building or managing a network system, we are more concerned about the availability of the network, that is, whether the network connectivity, but for its overall performance is often not

Int send (socket S, const char far * Buf, int Len, int flags ); Both the client and server applications use the send function to send data to the other end of the TCP connection. The client program generally uses the send function to send requests

http://blog.itpub.net/22664653/viewspace-714569/ Netperf is a network performance measurement tool, mainly for TCP or UDP based transmission, Netperf according to the application of different models of network performance testing, that is, bulk data

Socket message flow introduction and C code implementation, socket message flow code In actual software development, socket programming is often involved, that is, using socket to complete message interaction and command execution. This article

#表示SYN队列的长度, the default is 1024, which increases the queue length and can accommodate more network connections waiting to be connected. Net.ipv4.tcp_max_syn_backlog = 65536 #每个网络接口接收数据包的速率比内核处理这些包的速率快时, the maximum number of packets that

int close (int fd) (assuming server side)Close closes the two directions of its own data transfer. The default behavior of the close one TCP socket is to mark the socket as closed and then immediately return to the calling process. The socket

1.BackgroundWinsock Kernel buffer To optimize performance on the application layer, Winsock copies data buffers from application send calls to a Winsock Kernel buffer. Then, the stack uses it own heuristics (such as Nagle algorithm) to

Note: There is no explicit correspondence between active, passive and server, client. This figure n many people know that it helps to troubleshoot and locate network or system failures, but how do you keep this picture in mind? Then you must have a

After establishing a TCP connection with peer, first send a handshake message for handshakeThe handshake message format is as follows:One byte 0x19 + one string ' BitTorrent protocol ' + 8 byte reserved byte default value is 0 (reserved bytes are

In the actual software development work, often involves the socket programming, namely uses the socket to complete the message interaction and the command execution. In this paper, a C program is presented to explain the entire message execution

Many people have asked questions about the use of socket in WM. Let's make a demo. Some problems encountered during this demo are shared with you.   The server in socket communication uses tcplistener When tcplistner is instantiated, the IP
