Embodiment 1

[0047] Such as figure 2 As shown, in view of the problems existing in the prior art, the embodiment of the present invention provides a method for handling the fault of a bound network card. The method provided in the embodiment of the present invention can be applied in a scenario where multiple servers are interconnected through a switch. For convenience Description In this embodiment, the method provided by the embodiment of the present invention is described by taking the interconnection of two switches as an example:

[0048] Wherein, the method provided by the embodiment of the present invention can be applied to the first server, the first server is provided with at least two physical network cards, and the first server is respectively connected to the corresponding switch through the at least two physical network cards, so The first server is connected to the second server through the switch, and at least two communication channels are formed between the first server ...

Embodiment 2

[0067] Such as image 3 As shown, for the above method, the embodiment of the present invention also provides a server 300, the server is a first server 300 and is provided with at least two physical network cards, and the first server is respectively connected to the corresponding server through the at least two physical network cards. a switch, the first server is connected to the second server through the switch, at least two communication channels are formed between the first server and the second server through the at least two physical network cards, and the first Servers include:

[0068] A virtual network card generation module 301, configured to generate a corresponding virtual network card group for each of the at least two physical network cards, where the virtual network card group includes a probe virtual network card and a data virtual network card; wherein, the The probe virtual network card is used to send a probe message, the probe message is used to detect t...

Embodiment 3

[0077] In order to describe the method and device provided by the embodiment of the present invention in more detail, the following combination Figure 4 The server connection structure shown and Figure 5 The method flow provides a further detailed description of the solutions provided by the embodiments of the present invention, specifically including:

[0078] first Figure 4 The connection structure shown is specifically:

[0079] The two network cards are virtualized on the server S1, the physical network card NIC1 is virtualized as network cards vnic11 and vnic12, and the physical network card NIC2 is virtualized as network cards vnic21 and vnic22. Combine the four virtual network cards virtualized from server S1 as shown in the figure. vnic11 and vnic21 are combined as a group for fault detection. Vnic12 and vnic22 are bound together to communicate with the business layer. Do the same processing on server S2.

[0080] The fault detection module of server S1 uses v...

Abstract

The invention discloses a method and device for processing bonded network card faults. The method is applied to a first server, wherein the first server is provided with at least two physical network cards, respectively connected with corresponding switches through the at least two physical network cards, and connected with a second server through the switches. The method includes the steps that the first server generates a corresponding virtual network card set for each physical network card, wherein the virtual network card sets comprise probe virtual network cards for sending probes and data virtual network cards for sending data; when it is determined that the first probe virtual network card fails to receive or send probe information, it is determined that a communication channel corresponding to the first probe virtual network card is faulted. According to the method and device, the fault conditions of multiple communication channels between the servers can be automatically detected, and therefore the channels normal in communication are selected to guarantee the data transmission stability of the servers.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method and device for handling faults of bound network cards. Background technique [0002] Nowadays, almost all walks of life have established their own servers internally. Due to the special status of the server, its reliability and availability are very important. Maintaining high reliability and high availability of servers is an important indicator of an enterprise-level information technology (Information Technology, IT) environment, and the most important point is the high reliability and high availability of server network connections. In order to meet the high reliability requirements of the server network connection, most of the servers now adopt multiple network card configurations, and then a link aggregation technology that binds multiple network card interfaces of the server together appears. The link aggregation technology virtualizes multiple links int...
