The invention discloses a video networking system based on multicast technologies and a state monitoring method. The invention provides a distributed video monitoring system composed of systems, equipment and applications networked in a super large scale. Problems of real-time state monitoring and massive index data collection are solved. Each host of the video networking monitoring system is designed into an active participant for state information acquisition instead of a passive provider for providing monitoring information within its responsibility scope. Hosts in the system coordinate with one another so that work is organically distributed and influences of serialization and single-point faults are prevented. State data are reused and distributed in the network formed by the hosts. Therefore, phenomena that a certain host node bears too many loads and cannot work normally can be prevented. The coordination mode is characterized in that the polling capabilities are enhanced every time new host nodes are added. The monitoring capabilities will not be enhanced any more only when the network formed by the hosts stops increasing. Meanwhile, polling is separated from data storage and data presenting. Possible redundancy problems between data storage and data presenting in certain conditions can be solved.
