Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] refer to figure 1 , is a flowchart of a method for judging dual-homing automatic switching according to the number of registered gateways in an embodiment of the present invention. In the embodiment of the present invention, the method for judging dual-homing automatic switching according to the number of registered gateways includes the following steps:

[0040] Step S10, when the active server detects that the heartbeat coupling with the standby server is interrupted, it triggers the switching judgment mechanism of the standby server;

[0041] Step S20, the standby server detects the number of media gateways switched to the local machine according to the trigger signal of the switchover decision mechanism, and if the detected number of media gateways reaches the threshold, the state of the standby server is ...

Abstract

The invention discloses a method and system for performing dual-homing automatic switching judgment according to the number of registered gateways. The method comprises the following steps: triggering a switching judgment mechanism of a standby server when a master server detects that heartbeat coupling between the master server and the standby server is interrupted; enabling the standby server to detect the number of media gateways switched to a local machine according to trigger signals of the switching judgment mechanism, and if the number of the detected media gateways reaches a threshold, transferring the status of the local machine to be master and taking over responsibilities of the master server. The invention further provides a system for performing dual-homing automatic switching judgment according to the number of the registered gateways. According to the method and the system, the problem of abnormal switching or the dual-master status caused by transient faults of the standby server and simultaneous abnormity of heartbeat coupling and Mc port coupling and the like can be solved, and safety robustness of the switching judgment method is improved.

Description

technical field [0001] The invention relates to a softswitch dual-homing disaster recovery technology, and specifically describes how to judge and trigger an automatic switching method and system between dual-homing active and standby servers. Background technique [0002] With the wide application and maturity of dual-homing disaster recovery technology in softswitch systems, the requirements for the security and reliability of dual-homing technology are getting higher and higher. Among them, the safety and reliability of the dual-homing automatic switching decision determine whether the switching is necessary, whether the timing is accurate, and whether the impact on the system can be minimized to ensure the stability of the softswitch service. [0003] The existing common judgment method is that when the heartbeat coupling between the active and standby servers is abnormal, the original standby server opens the Mc interface and waits for the gateway to register. After the...
