Embodiment Construction

[0067] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0068] An embodiment of the present invention provides an arbitration method for remote disaster recovery. If the disaster recovery device does not receive the heartbeat signal sent by the master device within the preset time, it sends a network query request message to the network element device, and the network element device obtains the network connection status information with the master device after receiving the network query request message, T...

Abstract

The embodiment of the invention discloses a method for arbitration of remote disaster recovery. The method comprises the steps that if a heartbeat signal sent by a main device is not received by a disaster recovery device in a preset time, a network query request message is sent to a network cell device, the network query request message is received by the network cell device, network connection state information of the main device is obtained, a network query response message is sent to the disaster recovery device by the network cell device, and whether service data sent by the network cell device are taken over or not is determined by the disaster recovery device according to the network query response message. According to the method for arbitration of remote disaster recovery, when the network query request message sent by the disaster recovery device is received by the network cell device, whether the disaster recovery switchover is conducted or not is controlled according to the network connection state information of the main device, the network cell device serves as an arbitration party so as to control the disaster recovery device whether to take over the service data sent by the network cell device or not, the problem of center departure is solved, and the accuracy of arbitration of remote disaster recovery is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to an arbitration method for remote disaster recovery. Background technique [0002] In the cluster, a heartbeat network for communication is established between multiple independent hosts, and multiple independent hosts can be directly connected as an overall cluster. EMS (Element Management System, network element management system) can monitor and manage equipment alarms, performance statistics, configuration, logs and other information, and access the operator's OSS (Operations Support System, operation support system), which is convenient for operators to monitor and maintain the entire network equipment in a unified manner. Remote disaster recovery solutions can be divided into cold backup solutions, hot backup solutions, and warm backup solutions. [0003] In the existing technology, the remote disaster recovery solution uses third-party remote dual-machine software to provide remo...
