packet loss analyzer

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

UDP (packet length, packet collection capability, packet loss and process structure selection)UDP Packet Length: the theoretical length of a UDP packet What is the theoretical length of udp data packets and what is the proper udp

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

Whether you are a server administrator, a network administrator, or a VMware administrator, you use a protocol analyzer, also known as a data packet analyzer or a "sniffer", as a common tool for analyzing network problems. These software applications can analyze network traffic in real time, allowing you to view packets that pass through the network. These tools

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

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

whether there is any traffic exception. Network Traffic Analysis Process 1. Overall Network Traffic Monitoring We first use the History Samples historical sampling function of Sniffer Pro to monitor the network utilization on the image link. The following results are obtained: Link to utilization The link actually transmits numbers per second. From the above monitoring results, we can see that in every 40 seconds, the network traffic in this link will peak for 15 seconds, and it is very reg

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
