good.Internet programming is different because routers on the Internet may set the MTU to a different value. If we assume that the MTU is sending data to 1500来, and the MTU value of a network passing through is less than 1500 bytes, then the system will use a series of mechanisms to adjust the MTU value so that the datagram can reach its destination smoothly. Because the standard MTU value on the Internet is 576 bytes, it is best to use UDP data-length controls within 548 bytes (576-8-20) for U

between two routers, regardless of packet length or link transfer rate. queue delay and packet loss Queue Delay ratio LA/R is called flow intensityIf la/r >1, the average rate at which the bit arrives in the queue exceeds the rate at which the queue is transferred, the increase in the queue tends to be unbounded, and the queuing delay tends to be infinite. The

in front of the Libpcap capture packet, especially in the gigabit network conditions, a large number of drops, online search for a long time, probably all Pf_packet +mmap,napi,pf_ring and other methods, I pf_ring+libpcap experiment, The detection of gigabit network conditions, capturing the performance of the packet is very good, almost no packet

Https://www.tuicool.com/articles/7ni2yyr Recently work encountered a server application UDP lost packet, in the process of checking a lot of information, summed up this article for more people's reference. 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

UDP-based RTP transmission in the complex public network environment, especially 3G, 4G, WiFi network faced with packet loss, disorderly sequence, repetition, jitter and other issues, seriously affect the real-time audio and video interactive effect, even if it is a RTP packet lost, if the receiver does not do processing, will also lead to the appearance of video

Recently, I was working on a project. Before that, I had a verification program.It was found that the client sent 1000 1024 bytes of packets consecutively, and the server experienced packet loss.The reason is that the server has not completely processed the data, and the client has sent and disabled the data.I used sleep (10) to solve this problem temporarily, but this is not a fundamental solution. If the data volume is large and the network conditio

I don't know how to say it. In short, the boat, from the mouth, I can not see HUANGFA and impoverished! I'm not going to say anything except cursing!Prior to BBR, there are two kinds of congestion control algorithms, based on packet loss and delay-based, regardless of which is based on detection, in other words, packet loss
