Embodiment Construction

[0028] In practical applications, when the server that provides external data services in the DMZ domain is attacked and goes down, or the software that provides external services on the server fails, the egress router of the enterprise cannot detect the server failure in time, and network management personnel are usually required to monitor the server failure. Human intervention, after confirming the failure of the server, restart the server or switch the service to the preset standby server. That is to say, when the server fails, the external service function cannot be restored in time at present, which affects the access experience of external users.

[0029] Aiming at the problems in the above solutions, the present invention provides a method and device for switching DMZ servers. The technical solution of the present invention will be described in detail below with different embodiments.

[0030] In the first embodiment, the present invention provides a method for switch...

Abstract

The invention provides a DMZ server switching method and device. The method comprises the following steps that: TCP connection requests are regularly transmitted to main servers in a DMZ domain which provide data services for the outside, and if responses which are transmitted by the main servers according to the TCP connection requests are not received in preset time, it is confirmed that the main servers fail; and when the main servers fail, forwarding paths of data messages are switched to standby servers from the main servers. With the DMZ server switching method and device of the technical scheme of the invention adopted, the forwarding paths of the data messages can be timely switched to the standby servers when the main servers of an enterprise which provide the data services for the outside fail, and therefore, user experience can be enhanced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for switching a DMZ server. Background technique [0002] With the development of e-commerce, many small and medium-sized enterprises have also begun to build their own websites and e-commerce platforms. Currently, most small and medium-sized enterprises use a DMZ (Demilitarized Zone) between the internal network and the external network, and configure dedicated servers in the DMZ to provide data services for external users. This method can effectively protect the security of the local area network, and at the same time has a high cost performance, which is suitable for the development status of small and medium-sized enterprises. [0003] Please refer to figure 1 As shown in the schematic diagram of networking, small and medium-sized enterprises set up a DMZ domain between their internal LAN and external network, and set up server A in it to provide ...
