Problems solved by technology

[0006] However, under this scheme, the requirements for the central node are relatively high. Since the central node needs to retain the service session information on all service boards and perform encryption / decryption processing of all IPSec services, the central node is likely to become a performance The bottleneck cannot effectively improve the overall performance of the firewall device

Embodiment Construction

[0017] In order to achieve the purpose of the present invention, the core idea adopted by the present invention is: the distributed firewall of the present invention issues ACL (Access Control List, access control list) policy information to all interface boards in time through the main control board, so as to ensure that the information from specific network equipment Messages are sent to the corresponding interface board; and by synchronizing SA (Security Association) flow information to all service boards, when the service board finds that the received message does not belong to its own processing based on the SA flow information, The message is further redirected to the service board that matches the SA flow information. Through the aforementioned means, it can be ensured that the messages of the same flow are sent to the same service board for processing, thus realizing IPSec on the distributed firewall Load sharing of services.

Abstract

The invention relates to a method and a device for distributed firewall IPSec (internet protocol security) business load sharing. A master control board timely issues ACL (access control list) strategy information to all interface boards so as to guarantee that messages from specific network equipment are all sent to the corresponding interface boards; SA stream information is synchronized to all business boards, and when the business boards discover that the received messages thereof do not belong to themselves for processing according to the SA stream information, the messages are further redirected to the business boards matched with the SA stream information. By the means, the messages of the same stream can be enabled to be sent to the same business board to be processed, so that load sharing of IPSec business on a distributed firewall is realized.

Description

Technical field [0001] The invention relates to the field of data communication technology, and in particular to a method and device for distributed firewall IPSec service load sharing. Background technique [0002] Distributed firewalls process services in parallel through distributed multi-service boards to improve the processing performance of the whole machine, thereby meeting the needs of users for high concurrency, high new construction, and high throughput. [0003] Specifically, a distributed firewall device generally consists of an interface board, a service board, and a main control board. The interface board is used to receive and send messages, and send the messages to each service board through the switching network to process corresponding services; the service board is used to independently establish sessions, forward messages, and process QoS, As well as most services such as IPSec (IP Security) encryption, each independent service board can improve the service pro...
