Problems solved by technology

[0006] If real-time synchronization is performed for the micro-level update frequency, it will have a great impact on the performance of the VPN device and affect the normal operation of the device.
[0007] Traditional IPSecVPN data synchronization generally uses timing query to obtain synchronization data, which has a serious impact on system performance

specific Embodiment 1

[0034] A kind of IPSecVPN high-performance data synchronization method, setting waiting queue and synchronizing queue, adopting the batch synchronization based on timer, when data information item data changes, actively linking in waiting waiting queue, realize timing synchronization; Said waiting waiting waiting queue Used to link all data information items that have changed but have not started to synchronize; the synchronization queue is used to maintain all data information items that have changed and are being synchronized; the timer is responsible for initiating data synchronization according to the set timing threshold Features.

[0035] When the data of a data information item changes, the specific method of actively linking to the queue to be synchronized is as follows: set a linked list pointing to the queue to be synchronized in the data information item, and when the synchronization information in a certain data information item changes, the data information Items ...

specific Embodiment 2

[0043] The difference from the first embodiment is only that a listentry is set in IKESA, and when IKESA initiates or receives a DPD detection and a corresponding message, the listentry is hooked into the queue to be synchronized.

specific Embodiment 3

[0044] The difference with the specific embodiment 1 is only: a listentry is set in the IPSecSA to judge whether the current IPSecSA has performed a VPN process, if yes, then the anti-replay serial number or the anti-replay window has changed, and the current IPSecSA listentry is hooked into the queue to be synchronized.

Abstract

The invention provides an IPSec VPN high-performance data synchronization method; the method comprises the steps of setting a to-be-synchronized queue and a synchronizing queue, adopting batch synchronization based on a timer, and actively linking to the to-be-synchronized queue when data in a data information item changes, thereby realizing timing synchronization; the to-be-synchronized queue is used for linking all data information items which are changed but do not start synchronization; the synchronizing queue is used for maintaining all data information items which are changed and are being synchronized; and the timer is responsible for initiating a data synchronization function according to a set timing time threshold. The meaningless waste due to a fact that the traditional timing inquiry method cannot obtain whether the synchronous data is changed and inquires all items is saved; and meanwhile, the data copy due to timing inquiry is also reduced.

Description

technical field [0001] The invention relates to an IPSecVPN high-performance data synchronization method, in particular to a method suitable for synchronizing data between a master device and a backup device in an IPSecVPN hot standby or load balancing environment. Background technique [0002] IPSecVPN equipment needs to support dual-machine hot standby function and adapt to load balancing network, so as to realize the reliability of IPSecVPN equipment itself, as well as the reliable operation of the network and user services where it is located. The device needs to set the configuration parameter information before running, and a large amount of working data will be generated during the running process. In order to ensure that the other device can quickly participate in the work after one device fails, it is necessary to ensure that all information of the two devices in the same group can be consistent in real time. [0003] The configuration information required for devi...
