A Method for Realizing Configuration Synchronization Between Virtualized Devices

Abstract

The invention discloses a method for realizing configuration synchronization between virtualized devices. The method for realizing configuration synchronization between the virtualized devices is applied to configuration synchronization between the master device and slave devices in the cluster technology. According to the work process, the master device and the slave devices build data chaining, the master device carries out multicast configuration simultaneously on all the slave devices, and the master device and the slave devices judge whether configuration synchronization succeeds within timer time. If configuration of the master device fails, the configuration of the master device rolls back. If configuration of the slave devices fails, the slave devices carry out reconfiguration according to the instruction of the master device or leave the multicast group. The method for realizing configuration synchronization between the virtualized devices guarantees that all the member devices achieve configuration synchronization within a time constant range bearable for a user, can strictly control configuration consistence between the member devices, and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a configuration synchronization technology between devices. Background technique [0002] As the amount of network information continues to increase, network security becomes increasingly complex, and network security equipment is also facing increasing challenges in terms of performance and reliability. A virtualization technology that can expand the capacity of hardware and simplify the process of software reconfiguration came into being. Virtualization technology uses various control protocols to virtualize multiple devices into a single device for unified management, so as to simplify management, improve performance and improve network reliability. Configuration synchronization between devices is a prerequisite for the realization of virtualization technology.

Problems solved by technology

[0003] The traditional virtualized device configuration synchronization method is to send the configurations one by one to the slave device service process when the master device obtains the configuration, and then the master device does the configuration, and the slave device also does the same configuration. The master device and the slave device configure independently. The synchronization method mainly has the following disadvantages: 1) The master device sends the configuration to each slave device in a circular manner, which takes a long time and is inefficient; 2) The master device only sends the configuration to the slave device, and cannot know whether the slave device has received the configuration And what is the configuration result of the slave device; after the slave device receives the configuration, it only makes its own configuration, and does not know the configuration result of the master device; that is, there is no confirmation mechanism for the configuration of the master device and the slave device, and once they are inconsistent, there is no detection method and synchronization program, the consequences of which cannot be predicted and avoided

When the cluster size becomes larger and the number of member devices increases, such a strategy will become very inefficient

Moreover, in many abnormal situations, the configuration of the master device and the slave device will be inconsistent, such as: the communication between the master device and the slave device fails, the configuration service process of the master device and the slave device hangs, etc.

When the master device fails, the slave device cannot take over the business normally, and the consequences will be very serious
