Embodiment 1

[0024] In order to avoid the situation that the cloud host is disconnected from the network when the main gateway device fails, it is first necessary to make the equipment active and standby redundant, and then realize the active and standby automatic switching. Based on this, the present invention provides an OVS-based active and standby switching system. Such as figure 1 As shown, it includes a main gateway device, a backup gateway device and a host machine, and the host machine includes an OVS message control module, a master-standby switching module, a fault detection module, an alarm module and several virtual machines, and the OVS message control module It includes a physical network port module and a series of virtual network port modules. The physical network port module includes a main physical network port module and a backup physical network port module. The fault detection module includes a hardware fault detection sub-module and a software fault detection sub-modul...

Embodiment 2

[0030]For the master-standby switching system and its working principle in the above-mentioned embodiment 1, as figure 2 As shown, the present embodiment provides an OVS-based active-standby switchover method, the steps include:

[0031] S11, the hardware failure detection sub-module passes through the detection of whether the physical network port module fails, if the main physical network port module fails, then the main physical network port module is switched to the standby physical network port module for network communication through the active-standby switching module, At this time, the OVS message control module controls the virtual machine to perform network communication through the standby gateway device, and sends a warning that the main physical network port module needs to be replaced through the alarm module; if the standby physical network port module fails, the active and standby switching module Switch the standby physical network port module to the primary ...

Abstract

The invention discloses an OVS-based main / standby switching method and system. The main / standby switching system comprises main gateway equipment, standby gateway equipment and a host machine. The host machine comprises an OVS message control module, a main / standby switching module, a fault detection module, an alarm module and a virtual machine. The OVS message control module comprises a physicalnetwork port module and a virtual network port module. The physical network port module comprises a main physical network port module and a standby physical network port module. The fault detection module comprises a hardware fault detection sub-module and a software fault detection sub-module. The virtual machine comprises a virtual network card module. The main gateway equipment is connected with the OVS message control module through the main physical network port module. The standby gateway equipment is connected with the OVS message control module through the standby physical network port module. The OVS message control module, the main and standby switching module and the fault detection module are connected in sequence. According to the invention, when the gateway equipment breaksdown, the system automatically switches to other gateway equipment quickly; network communication is not interrupted; and the stability of data transmission is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of gateway equipment for cloud computing virtual machines, in particular to an OVS-based active-standby switching method and system thereof. Background technique [0002] OpenvSwitch, referred to as OVS, is a high-quality, multi-layer virtual switching software. Its purpose is to support large-scale network automation through programmatic extensions, while also supporting standard management interfaces and protocols. OVS can be used in production environments, supports distributed management across physical servers, extended programming, large-scale network automation and standardized interfaces, and implements software switches with functions similar to most commercial closed-source switches. [0003] At this stage, network virtualization is an important technology in the field of cloud computing. Cloud hosts usually need to use network virtualization technology to communicate with the Internet, an...
