Embodiment Construction

[0020] The applicant analyzed the existing security cluster processing mechanism and found that session backup between security nodes in the cluster occupies the session resources of the nodes themselves, resulting in the inability to linearly increase the session performance of the cluster. Taking 1:1 backup as an example, the most In the worst case, the session size of the cluster as a whole is 1 / 2 of the sum of the individual node sizes.

[0021] figure 2 It is a flowchart of a method for synchronizing secure cluster session information provided by an embodiment of the present application, and its specific steps are as follows:

[0022] Step 200: Preset a security gateway, which is located outside the security cluster and communicates with multiple security nodes in the security cluster through a management link.

[0023] The security gateway can be a physical security gateway, or a virtual security gateway located on a physical server.

[0024] The "management link" in ...

Abstract

The invention provides a method and device for synchronizing session information of a security cluster. The method comprises the steps that a security gateway is preset, wherein the security gateway is located outside the security cluster and is in intercommunication with a plurality of security nodes in the security cluster through a management link; the security gateway receives a session synchronization request message sent by any security node in the security cluster through the management link and synchronizes the session information corresponding to a session identifier in the session synchronization request message according to a synchronization type identifier in the session synchronization request message. By means of the method and device, the session performance of the security cluster is improved.

Description

technical field [0001] The present application relates to the technical field of security clusters, in particular to a method and device for synchronizing session information of security clusters. Background technique [0002] Security devices refer to devices that specifically implement security policies in the network, such as firewall devices. The rise of cloud computing, big data and other emerging technologies has generated more data in the network, and the performance requirements for security devices have also increased exponentially. Limited by the performance limitation of a single physical security device, how to smoothly expand the performance of the security device without causing the complexity of management deployment has become an urgent problem to be solved by the security device. Security cluster is a multi-virtual-one virtualization technology that can effectively solve the above problems. [0003] The networking form of the existing security cluster is s...
