57652 0-57652-D is a network card binding technique in Linux systems, which can abstract (bind) n physical network cards on a server into a logical network card within the system. It can improve network throughput, achieve network redundancy, load, and other functions.

57652 0-57652-D technology is implemented at the kernel level of Linux systems and is a kernel module (driver). The principle is to aggregate multiple physical network cards into a virtual network card. One network card is working normally, while the other network cards are used as backups. At regular intervals (specific time intervals are related to the miimon parameter, measured in milliseconds), a status inquiry is sent to the working network card. If there is no reply, it is considered that the operation has failed, and the backup network card will be enabled, but the IP address will not change.
