Hotspare method and system suitable for device for processing and forwarding IP media stream in real time

Abstract

The invention discloses a hotspare method and a system suitable for a device for processing and forwarding an IP media stream in real time. The method comprises the following working steps that: (1) two devices are simultaneously accessed to a network, wherein one is configured as a main machine, while the other one is configured as a slave machine; (2) the main machine and the slave machine synchronously operate and simultaneously process the IP media stream; the main machine processes, forwards and outputs the IP media stream; the slave machine only processes the IP media stream without forwarding and outputting the IP media stream; (3) the main machine periodically sends a heartbeat signal to the salve machine through a heartbeat communication interface; and (4) the slave machine carries out real-time monitoring in a working state of the main machine through the heartbeat communication interface; when the slave machine detects the fault of the main machine, the slave machine immediately replaces the main machine and outputs the processed IP media stream; when the slave machine detects that main machine recovers to the normal state, the slave machine immediately stops outputtingany IP media stream; and the main machine takes charge of the processing and the forwarding of the media stream again. According to the method and the system, when the main machine has the fault, thesystem can detect the problems and rapidly switch in time, has short response time and is in particular applicable to the hotspare requirement of IPTV and other live servers.

Description

technical field [0001] The invention relates to a network multimedia hot backup technology, in particular to a hot backup method and system suitable for IP stream media real-time processing and forwarding equipment. Background technique [0002] Today, my country's communication industry is developing rapidly, and users have higher and higher requirements for information services, especially broadband video information, so the IP media stream provided to users must have high reliability. In the IP streaming media system, many key devices are equipped with a redundant mechanism of master-slave dual-machine hot backup. [0003] Dual-system hot backup means that for important services, two servers are used to back up each other and jointly execute the same service. When one server fails, another server can take over the task, so that the system can automatically ensure that the system can continue to provide services without manual intervention, which solves the problem of ser...

Problems solved by technology

Disadvantages: Both of these two methods require dual-machine management software, which is very expensive, and is difficult to expand due to the version number of the system; the system is limited by the ability of the dual-machine management software, and the switching time is generally tens of seconds or even longer , business is prone to interruption
