Embodiment Construction

[0039] Considering that in the OpenFlow network environment, the application servers are all connected to the OpenFlow switch, and any flow of the OpenFlow switch will be reported to the OpenFlow controller. Therefore, in order to achieve the purpose of the present invention, the core idea adopted by the present invention is: through Let the active server receive the heartbeat message of the OpenFlow controller to determine whether its network is normal, instead of sending heartbeat messages between the active server and the backup server to confirm whether the other party is alive or the network is abnormal, thus effectively avoiding misjudgment .

[0040] In order to make those skilled in the art more clear and understandable, the specific implementation of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0041] Please refer to figure 2 , is a schematic flowchart of the dual-system hot backup method provided by the...

Abstract

The invention discloses a dual-computer hot backup method and device, which are applied in an OpenFlow network environment, and the OpenFlow network environment includes an application server, an Openflow switch and an Openflow controller that need mutual backup. In the present invention, it is determined whether the network of itself is normal by allowing the active server which remains connected to the Openflow controller to receive the heartbeat message sent by the OpenFlow controller, instead of sending a heartbeat message between the active server and the backup server for confirmation Whether the other party is alive or the network is abnormal, so misjudgment can be effectively avoided.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for dual-computer hot backup based on an Open Flow network environment. Background technique [0002] With the continuous development of Internet services, Internet services require shorter and shorter deployment time on the Internet. For example, a few years ago, a service deployment often took several months and required a lot of manpower. Now an Internet service may require a small amount of manpower to be deployed within a few days. How to quickly deploy an Internet service involves some new technologies, such as SDN (Software Defined Network, software-defined network). Under the model defined by SDN, the rapid deployment of services can be realized through software, thereby reducing manpower input , to shorten the construction period. Among many SDN technologies, OpenFlow is the most representative one. [0003] Such as figure 1 As shown in , it is a...
