Problems solved by technology
The defect of the dual-machine mutual backup system is the performance bottleneck. One server runs two applications at the same time, the load is too large, and the performance is halved; 3) Master-slave redundant system, that is, two servers run the same application, and one of them is used as the host Provide services to the outside world, while the other one is in a backup state to detect the running status of the host in real time

Embodiment Construction
[0076] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0077] Combine below figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 The present invention is further described in detail.
[0078] Such as image 3 As shown, the VoIP dual-redundant system based on dynamic master-standby decision-making and distributed synchronization capability of the present invention includes a core switching unit 1, a media control unit 2, a master-standby control unit 3 and a system operation and maintenance unit 4; The IP network bus interconnects and exchanges control commands and data.
[0079] The core switching unit 1 is the core control and processing unit of the entire VoIP system, and supports running in a cross-platform environment of multiple operating systems of Windows and Linux. This unit is used to receive the session application from the terminal VoIP device, perform core scheduling processing, feed...

The invention discloses a communication system based on a VoIP dual-redundancy switching server, which realizes the cooperative operation of a dual-voice server system by using a real-time dynamic main and standby decision mechanism and a cooperative distributed synchronous design thought. When the main server operates normally and processes the VoIP service, a distributed synchronization architecture is adopted to update memory data generated by service operation to the standby server in real time so as to ensure data synchronization of the standby server and the main server; when hardware or software faults occur in the operation of the main server, the standby server can realize zero-millisecond seamless switching, so that the link quality of the current online call is not changed, a user cannot sense the change of the system, and the reliability and robustness of the operation of the system are improved.
Description
technical field [0001] The present invention relates to a VoIP dual-redundancy switching server based on dynamic active-standby decision-making and having distributed synchronization capability, in particular to a communication system based on VoIP dual-redundancy switching server. Background technique [0002] As the business volume of domestic and foreign air transport continues to increase, the pressure on its control is increasing day by day. As the main means in the field of control and command and control, the importance of reliable operation of voice communication is self-evident. At present, most of the voice communication systems in domestic airports are still based on the configuration of a single server architecture. Due to the lack of backup support for temporary failures, the reliability of the system is greatly reduced. For airports with relatively busy businesses, voice interruptions caused by temporary server failures may cause incalculable loss. [0003] A...
