Embodiment 1

[0043] This embodiment proposes a dual main control board hot standby switching method, which can be applied to an access gateway device with two main control boards, such as a security access gateway or a security authentication gateway. For example, figure 1 A security network system is shown, and the security network system may include a security information cloud system (that is, a cloud server), at least one security access gateway, at least one access user, and the like. In order to ensure the reliability of user access and communication, the secure access gateway usually has two main control boards, that is, one is the main main control board, and the other is the standby main control board. Therefore, when the main main control board fails, the standby main control board can switch to the new main main control board in time and continue to process services. Wherein, the secure access gateway may adopt the dual main control board hot standby switching method proposed i...

Embodiment 2

[0071] Please refer to Figure 6 , based on the dual main control board hot standby switching method in the above-mentioned embodiment 1, this embodiment proposes a dual main control board hot standby switching device 1, which can be applied to an access gateway with two main control boards. The dual main control board hot standby switching device 1 may include: a status information acquisition module 10 , an authentication status judging module 20 and a switching control module 30 .

[0072] Wherein, the state information acquisition module 10 is mainly used for two main control boards to send state information to each other, wherein the state information includes the authentication state of the sender main control board;

[0073] The authentication state judging module 20 is mainly used for the receiver main control board to judge whether its own authentication state is the same as that of the sender main control board, wherein the authentication state includes a connected u...

Embodiment 3

[0077]Based on the hot standby switchover method of the above-mentioned embodiment 1, this embodiment proposes an access gateway, which can be used for terminal access or authentication. Specifically, the access gateway may include two main control boards, and the two main control boards will adopt the dual main control board hot standby switching method in the first embodiment above.

Abstract

The invention discloses a dual-main control board hot-standby switching method and device, an access gateway and a safety network system. The method comprises the following steps: two main control boards send state information to each other, wherein the state information comprises an authentication stage of a sender main control board; a receiver main control board judges whether the own authentication state is same as the authentication stage of the sender main control board, wherein the authentication stage comprises a connected uplink state and a unconnected uplink state; if the judging result is that the authentication state of the receiver main control board is different from that of the sender main control board, the main control board with the connected uplink state at the authentication state is switched as the master main control board. According to the technical scheme disclosed by the invention, two main control boards can realize reliable main-standby switching, unnecessaryswitching frequency between two main control boards can be reduced, the reliability of the access gateway is improved, and an access state of the user can be well guaranteed.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a dual main control board hot standby switching method, device, access gateway and safety network system. Background technique [0002] In a secure network system, all users who need to communicate through the network must first access the network and obtain the authentication of the network system before they can communicate through the network system, and the online authentication of these users is provided by the access gateway. to be responsible for the completion. However, if a problem occurs during the authentication process of the access gateway, the user cannot communicate and has to go online again. Therefore, the access gateway usually has a dual main control board hot standby switching mechanism to prevent the failure of the main main control board and still ensure that the user's online authentication can be carried out normally.
