Problems solved by technology

The disadvantage of this method is that when a network card (port) is in an invalid state, the non-invalid MAC can only be in a down state, occupying the PCIe channel resources of the CPU in vain

Embodiment 1

[0037] Embodiment 1, in the network card failover system provided by this embodiment, such as figure 2 As shown, the switching module 4 includes: the first switching switch 6 and the PHY module 7 whose quantity matches the number of the network interface module 5; A matching network interface connection end; the controller 1 is connected to the data connection end of the first switch 6 through the MAC module 3, and each PHY module 7 is connected to the network interface connection end of the first switch 6 respectively; each PHY module 7 Corresponding to a communication connection with a network interface module 5; the controller 1 is sequentially connected to the network interface module 5 through the MAC module 3, the first switch 6 and one of the PHY modules 7; the controller 1 is connected to the control terminal to control the first The toggle switch 6 performs a switching action.

[0038] In this embodiment, the switching module 4 is provided with a plurality of PHY mo...

Embodiment 2

[0039] Embodiment 2, in the network card failover system provided by this embodiment, such as image 3As shown, the switch module 4 includes: a second switch 8 and a PHY module 7; the second switch 8 sets the data connection end, the control end and the network interface connection end whose number matches the number of the network interface module 5; the controller 1 The MAC module 3 and the PHY module 7 are connected to the data connection end of the second switch 8 in turn, and each network interface connection end of the second switch 8 corresponds to a network interface module 5 connected to the controller 1 through the MAC module 3 in turn, The PHY module 7 and the second switch 8 are communicatively connected with a network interface module 5; the controller 1 controls the second switch 8 to perform a switching action by connecting with the control terminal.

[0040] Compared with the first embodiment, this embodiment is different in that a PHY module 7 is provided, and...

Embodiment 3

[0042] Embodiment 3, this embodiment can be combined with any one of the technical solutions of Embodiment 1 and Embodiment 2. This embodiment includes: a fault detection module; the fault detection module is connected with the controller 1, and the fault detection module is used to detect the connection state between the network interface module 5 and the network cable port, when the fault detection module detects that the network cable port is loosened, the network interface module At 5 o'clock, a network failure signal is sent to the controller 1, and the controller 1 sends a switching control command to the control terminal of the switching module 4, so that the switching module 4 switches the network interface module 5 currently connected to the controller 1 through communication. This is based on the detection and switching of faults formed when the network cable port is loose.

[0043] That is, when the fault detection module detects that the network cable port is loose...

Abstract

The invention provides a network card failover system, comprising: a controller, a MAC module, a switching module and at least two network interface modules; interface connection end; the controller is connected to the data connection end of the switching module through the MAC module, and each network interface module is respectively connected to the network interface connection end of the switching module; the controller communicates with one of the network interface modules; the controller also communicates with the control When the network interface module communicating with the controller fails, the controller sends a switching control command to the control terminal of the switching module, so that the switching module switches the network interface module currently communicating with the controller. The failover function of the network can be realized by improving the structure of the network card itself without adding network cards.

Description

technical field [0001] The invention relates to the server field, in particular to a network card failover system. Background technique [0002] A large number of high-performance servers are used in the era of cloud computing. More and more network servers will use dual network cards (or dual network ports) to access, one path is in the master state, and the other path is in the slave state; (backup) takes over the main state. Network faults generally occur outside the I / O of the network card, such as poor connection of the network cable (loose connector), disconnection of the network cable itself at the media layer, and damage caused by electrostatic lightning. That is, faults mostly occur at the PHY physical layer and the external media layer. [0003] The existing way to solve network failures is generally two-way MAC (Media / Medium Access Control, or the physical address of the network) and PHY (PHYPhysical Layer, the physical layer of the network) for redundancy to ac...
