Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 In the described embodiment, a kind of heartbeat-based dual-computer hot backup method includes two directors and a live server, the director is connected to the live server, and the core of each director includes two parts, heartbeat monitoring Part and resource takeover part, specifically include the following steps:
[0027] (1) The heartbeat monitoring part is carried out through the wireless network card link. The main broadcaster sends messages regularly to tell the standby broadcaster its current status; specifically: when performing heartbeat detection through IP, the active and standby dual broadcasters will pass the heartbeat path (TCP / IP protocol) periodically sends out detection test packets. When the system is normal, the main broadcaster provides live broadcast services for the system, and the standby bro...
