The main reasons of network congestion: improper user requirements or their own problems such as switches. Assuming that the network conflict is traffic jam, we can know that the traffic jam is caused by the irregular behavior of vehicles, and so is the network conflict, in which the transmission of data packets is vehicles.

Network congestion is a network conflict, which is caused by the phenomenon of repeated or reset network connections. Information boxes are used to prompt network conflicts or bubbles are used to prompt, such as asking to switch to tasks and balloon prompts on the taskbar computer.

As far as the architecture of the Internet is concerned, the occurrence of congestion is its inherent attribute. Because in a resource-sharing network, it is possible that several IP packets arrive at the router at the same time and expect to be forwarded through the same output port, without any negotiation and permission request mechanism in advance.

Obviously, not all packets can be processed at the same time, there must be a service order, and the buffer on the intermediate node provides some protection for the packets waiting for service. However, if this situation persists, when the cache space runs out, the router can only discard the packet to ensure that the network can avoid locking.
