What does network packet loss rate mean? How to solve network packet loss problem?

What does the network packet loss rate here mean? When it comes to network packet loss rate, it means that during the data transmission process of our data packets, some data packets are lost due to mid-transmission. Today, the editor searched for a keyword on the Internet which is network packet loss rate. What does the network packet loss rate here mean? Speaking of network packet loss rate, it means that during the data transmission process of our data packets, some data packets are lost due to mid-transmission. That is, network packet loss. So how to solve the network packet loss during network transmission? So let’s talk about the specific content of network packet loss. The data packets formed on our network are transmitted to another database through channels. Generally, during the network transmission process, a small part of the data packets will be lost due to some reasons, such as the distance is too large, while most of the data packets are successfully transmitted to on the terminal database. This forms a process of network packet loss. The size of the packet loss and the size of the transmitted data packet are the network packet loss rate. For example, a factory buys a truckload of goods at location A and then transports them to location B. Due to porters' handling and other reasons, the value of this batch of goods is less than that measured at location A. This process is the loss of goods. Therefore, it is the network packet loss in the network, and the ratio of the lost goods to the total amount of goods is the network packet loss rate. Usually these are just wear and tear and are normal. How to check the network packet loss rate? Click "Start-Run" on the taskbar, enter the cmd command in the run dialog box, execute the command to open the command prompt, type "ping [website address]" in the interface, the last line displayed (x% loss) is the correct The packet loss rate of ping packets from the target address. How to solve the network packet loss rate? Network packet loss is a phenomenon in which data packets are lost in the channel due to various reasons when we use ping (to detect whether a system is running normally) to query the destination station. Ping uses ICMP echo request and echo reply messages. The ICMP echo request message is a query sent by a host or router to a specific destination host. The machine that receives this message must send an ICMP echo reply message to the source host. This query message is used to test whether the destination station is reachable and to understand its status. It should be noted that ping is an example of using network layer ICMP directly, it does not go through UDP or TCP at the transport layer. 1. Physical line failure If the network packet loss is caused by a physical line failure, it means that the fault is caused by the line provided by the line supplier. You need to contact the line supplier to solve the problem as soon as possible. Contact your service provider to resolve severe network packet loss. 2. Equipment failure Equipment mainly includes improper software settings, network equipment interface and fiber optic transceiver failures. This situation will cause the switch port to be in a dead state. Then you can replace your fiber optic module with a new one. 3. The network is blocked and congested. When the network is not powerful, more packets will be lost on the network when transmitting data through the network. This is usually caused by the router occupying a large amount of resources. The solution is to use show process cpu and show process mem at this time. Generally, it is found that the IP input process takes up too many resources. Next, you can check whether fast switching is disabled on the high-traffic egress port. If so, you need to use it again. Use the show interfaces and show interfaces switching commands to identify the ports through which a large number of packets enter and exit. Once the incoming port is confirmed, open IP accounting on the outgoing interface to see its characteristics. If it is an attack, the source address will continue to change but the destination address will not change. You can use the command "access list" to temporarily solve this problem. 4. Routing error. The path error of the router in the network will also cause the data packet to not be transmitted normally to the host database. This situation is normal, and the data lost is also very small. So users can ignore these data packet losses, and this is unavoidable. The above is all about what network packet loss rate means and how to solve network packet loss. I hope it will be helpful to you.
