Problems solved by technology

In this method, on the one hand, the number of transmission channels of the external equipment increases, on the other hand, it is difficult for the master and backup machines to achieve transparency to the external equipment, so the availability of the system will be reduced
[0007] None of the above approaches achieves the problem of "doubly fully redundant computers and networks in a transparent manner"

specific Embodiment approach

[0039]Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, it is assumed that the redundant network is composed of two networks: X network and Y network, and the redundant computer group C1 is composed of two computers: C11 and C12. The other equipment outside the redundant computer group is called C2, and C2 may be a computer, or it may be a redundant computer group consisting of multiple computers.

[0040] Step 1. The redundant computer group configures a fixed public IP address for each network in the redundant network:

[0041] (1-1) For a redundant computer group, each network in the redundant network corresponds to a fixed public IP address. For example figure 2 , image 3 , Figure 4 As shown in , R1 and B1 are the public IP addresses corresponding to the redundant computer groups on the X network and the Y network respectively.

[0042] (1-2) Each computer in the redundant computer group is connected to each network in the redundant network through a...

Abstract

The invention relates to a method for the communication of a thermal backup redundant computer with other equipment by a redundant network. The method comprises the following steps: (1) configuring a fixed open IP address respectively for each network in the redundant network by a redundant computer group; (2) taking the fixed open IP addresses as transmitting addresses when the redundant computer group transmits data to other equipment; and (3) taking the fixed open IP addresses as receiving addresses when other equipment transmits data to the redundant computer group. Compared with the prior art, the invention has the following advantages of realizing computer redundancy and network redundancy under a condition that the hardware cost is not increased additionally, compromising the transparence of the computer redundancy and improving the reliability and the usability of a distributed computer system.

Description

technical field [0001] The invention relates to a method for communication between a network and a device, in particular to a method for a hot standby redundant computer to communicate with other devices through a redundant network. Background technique [0002] In a high-reliability distributed computer system, there are often two or more redundant computers to perform the same work. When one computer fails, another computer is used to replace it. There are usually two working modes for redundant computer clusters: cold standby and hot standby. In the cold standby mode, only one of the computers is working at any time, which is called the main computer; the other computers are shut down or hibernated, called the standby computer; when the main computer fails, an available standby computer is started or awakened to replace it It works. At this time, the standby machine is renamed as the main machine, and the original main machine is renamed as the standby machine. In the h...
