Summary: The key to the problem is to set up your intranet to see if there is half duplex, especially hubs, network cables, interfaces and viruses. If necessary, disconnect the whole network, connect a computer to 65, and test whether there is packet loss. If the problem persists, the problem appears on the 65 switch. If there is no problem, the problem lies in the intranet.

Packet loss, as its name implies, refers to the loss of communication packets in communication.

Data is transmitted in the form of data packets on the communication network, and each data packet contains frames representing data information and providing data routing. In other words, no matter how good the network is, data is not transmitted continuously in a linear way (just like making a phone call), and there will always be a hole in the middle.

The transmission of data packets can not be completely completed, because there will always be some losses due to physical line failure, equipment failure, virus attack, routing information error and other reasons.

In this case, the network will automatically make both ends of the communication form data packets according to the protocol. If the line is in good condition and the speed is high, the packet loss will be small, and the packet repair work will be relatively easy to complete, so the data can be approximately regarded as lossless transmission.

However, if the line is not good (such as using a modem), the data loss will be very large, and it is impossible to complete the packet repair work 100%. In this case, data transmission will be vulnerable, resulting in packet loss.
