how to troubleshoot packet loss in network

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-leng

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

Troubleshoot malicious packet sending and packet sending on the server On the 30th, I found that the traffic of one server in another service line of my data center was extremely high (the outbound traffic of a single server exceeds 900 MB), and the access to the server was particularly slow due to the impact of traffic on service access. We suspect that this lin

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

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

Problem DescriptionWhen you use a vro to access the Internet, the network speed is slow or unstable, and packet loss occurs on the ping Internet, as shown in the figure below:Ping packet loss is generally caused by physical connection quality or line congestion. We will anal

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
