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 method, a system and equipment for processing data in real time in double-machine standby technology; the method comprises the following steps that: double-machine equipment generates a corresponding response message according to a request message and judges the self working state; when the working state is active, the double-machine equipment is main equipment; the main equipment sends the response message to exchange equipment; the exchange equipment forwards the response message; when the working state is standby, the double-machine equipment is backup equipment; and the backup equipment abandons the response message. The method, the system and the equipment ensure the real-time data processing and cannot delay time.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and equipment for real-time data processing in dual-machine hot backup technology. 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 ...
