Description
Technical Field
The invention relates to the field of servers, in particular to a network card fault switching system.
Background
In the cloud computing era, a large number of high-performance servers are applied, more and more network servers are accessed by using double network cards (or double network ports), one network server is in a master state, and the other network server is in a slave state; when the master port (Active) is down, the slave port (backup) takes over the master state. Network failures generally occur outside the I/O of the network card, such as poor contact of the network cable (loose connector), disconnection of the medium layer network cable itself, and electrostatic lightning damage. I.e., failures occur in the PHY physical layer and in the external media layer.
The existing method for solving network failure generally includes redundancy between a two-way MAC (Media/Medium Access Control, or referred to as a physical address of a network) and a PHY (PHY, i.e., a physical Layer of the network) to implement failover. The disadvantage of this approach is that when a network card (port) is in a failure state, the MAC without failure can only be in a down state, and the PCIe channel resource of the CPU is occupied unnecessarily.
