Problems solved by technology

However, when performing active-standby switchover through the above two methods, when the active virtual gateway is working, the backup virtual gateway is usually in an idle state, resulting in a great waste of network bandwidth resources and server resources.

Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] As in the background art, at present, when the active / standby switchover of the virtual gateway is performed, the ARP protocol or the active / standby routing mode is usually used to perform the active / standby switchover of the virtual gateway. However, when the master-standby switchover is performed through the above two methods, when the master virtual gateway is working, the backup virtual gateway is usually in an idle state, resulting in a great waste of network bandwidth resources and server resources.

[0031] In order to solve the above problems, the embodiment of the present invention provides an SDN controller-based virtual gateway active / standby switching method, such as figure 1 As s...

Abstract

The invention discloses a virtual gateway primary and backup switching method and device based on an SDN controller, relates to the technical field of network, and achieves that the primary and backupvirtual gateways are in a working condition at the same time to avoid that a virtual gateway is in an idle state, thereby saving bandwidth resources and server resources of a network. The method comprises the steps that it is judged whether or not primary paths respectively corresponding to a first virtual gateway and a second virtual gateway in a same virtual network are in a normal state through the SDN controller; if the primary path corresponding to the first virtual gateway is out of order, a backup path corresponding to the first virtual gateway is switched to the primary path of the second virtual gateway, or if the primary path corresponding to the second virtual gateway is out of order, a backup path corresponding to the second virtual gateway is switched to the primary path of the first virtual gateway; the switched backup path transmits a message sent from a virtual machine. The virtual gateway primary and backup switching method and device based on the SDN controller are applicable to the virtual gateway primary and backup switching based on the SDN controller.

Description

technical field [0001] The present invention relates to the technical field of network technology, in particular to a method and device for virtual gateway active / standby switchover based on an SDN controller. Background technique [0002] With the continuous development of network technology, a network address translation technology (Network Address Translation, NAT) appears. Since the packets sent by the virtual machine are usually network packets, and the source Internet Protocol (Internet Protocol, IP) address of the network packets is a private network address, it is usually necessary to perform NAT processing on the packets sent by the virtual machine through the virtual gateway. In practical applications, the number of packets processed by the virtual gateway at the same time is very high, and the performance requirements of the virtual gateway are very high. The virtual gateway may become a communication bottleneck and a single point of failure is prone to occur. Th...
