Embodiment Construction

[0033] The core idea of ​​the present invention is to configure the same unicast IP address on the main device and the backup device through the method of static configuration IP, and correspondingly configure the same multicast MAC address statically on the main device and the backup device, according to the unicast IP Addresses and multicast MAC addresses Statically configure ARP entries on the switching device, so that all request packets from the client can be sent to the master device and the backup device according to the ARP entry, and the master device and the backup device report The corresponding response message is generated by the text. Before sending the response message, it judges its own working status. When it knows its own working status as the master device, the master device returns a response message to the client. When it knows its own work status When the status is the backup device, the backup device directly discards the response message, thus ensuring t...

Abstract

The invention discloses a double machine hot switch processing system for a server. The method comprises the steps that the double machine device generates corresponding response report based on the request report, and the self working state can be determined; when the working state is for main use, the double machine device is the main device, which sends the response report to the switch device,and the response report is forwarded by the switch device; when the working state is for standby use, the double machine device is a backup device, which abandons the response report. The invention is advantageous in that real-time processing of the data can be guaranteed, and no time delay will occur.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a server dual-machine hot switching processing system. Background technique [0002] In the current networking applications, users have higher and higher requirements for network reliability. For some important service entrances or access points (for example, Internet access points of enterprises, database servers of banks, etc.), it is necessary to ensure that the network Uninterrupted transmission, and when a device (for example, an enterprise Internet access point device) fails, it will cause all network services between the internal and external networks to be interrupted. That is, if only one device is used on an important service entrance or access point, no matter how high the reliability of the device is, the system needs to bear the risk of network interruption caused by a single point of failure. [0003] In order to solve the above-mentioned problem that the us...
