Problems solved by technology

[0002] Today, with the rapid development of science and technology, the use of computer groups, especially local area networks, is more and more widely used in various enterprises. Each node in the local area network can only be accessed through the server in the local area network. If the server fails, such as If the server crashes or the server is powered off, each node cannot access each other and can only become an independent office computer, which seriously affects the efficiency of the office. Only by other means can the data of this node be copied to another node, which is time-consuming , more resources are occupied, the cost is high and the efficiency is low
[0003] Of course, we can solve this problem by adopting uninterruptible power supply such as UPS and having an extra server, but the cost will be higher, which is not what every boss is willing to see

Embodiment Construction

[0016] In order to make the present invention easier to understand, the following combination figure 1 , figure 2 , image 3 , Figure 4 for a more detailed explanation.

[0017] In order to achieve the above purpose, we adopt the following methods:

[0018] 1) Connect two nodes in the local area network to the relay in the firewall server, make the relay in dynamic state when the firewall server works normally, and make the relay in static state when the firewall server breaks down or loses power;

[0019] 2) Add the watchdog function to the firewall server, so that the firewall server will automatically restart when it fails, and the firewall server will also automatically restart when a sudden call comes in after the firewall server is powered off;

[0020] 3) The bypass function added to the firewall server, when the server fails, the bypass and gpio generate control signals at the same time, so that the relay returns to static state, and the two nodes in the LAN are ...

Abstract

The invention relates to a method for two nodes in a local-area network (LAN) to still communicate with each other when a fire wall server encounters failure or power cut, and for the server to automatically restart when power is resumed after the failure or power cut. By adding WATCHDOG and BYPASS functions to the fire wall server, the fire wall server can automatically restart when power is suddenly resumed in the event of failure and after power cut, and can maintain the communication between the two nodes in the LAN. Therefore, no additional backup service or backup electric generator is required, thus saving cost.

Description

technical field [0001] The invention relates to a firewall server, in particular to a method for communicating in a local area network when the firewall server fails or is powered off. Background technique [0002] Today, with the rapid development of science and technology, the use of computer groups, especially local area networks, is more and more widely used in various enterprises. Each node in the local area network can only be accessed through the server in the local area network. If the server fails, such as If the server crashes or the server is powered off, each node cannot communicate with each other, and can only become an independent office computer, which seriously affects the efficiency of the office. Only through other methods can the data of this node be copied to another node, which is time-consuming , has taken up more resources, high cost and low efficiency.
