This method includes：
Some equipment are combined to form into distributed type assemblies 100, if the cluster include at least Centroid 110 and
Client 120 is done, cannot be communicated between each client 120.
Application program 200 is only capable of communicating with the client of cluster 120, and the upper of status information is carried out to client 120
Report 210, and stored by client, or the state parameter to be asked (i.e. type) is sent to the client 120 in cluster,
And receive the operation 220 of the status information of client return.
After the client 120 is automatically performed state synchronized (data-pushing) with Centroid 110, Centroid will be connect again
Received status information synchronizes (data pull) with other clients, these other clients are also by Centroid synchronization
State information storage.
One state collection of scheme provided in this embodiment and storage system, are data storage substantially, can store
Include any data including state.The system uses distributed structure/architecture, is made of a Centroid and multiple client.Should
It can only be communicated with program with client, client can be automatically performed state synchronized with Centroid.Simultaneously as it is distribution
Formula, when Centroid is delayed machine, has no effect on the communication of application program and client.It is, application program can normally report,
Obtain the status information related with some type.
Application Status reports, stores and can only be completed by client, it is, application program is state reporting
To client, then client can be automatically synchronous with Centroid completion, meanwhile, Centroid also can be same by the status information
Other clients are walked, cannot be communicated between each client, it is necessary to which being used as bridge by Centroid just can be with.
All status informations can be sorted out by the way of by type, and its data is stored in centromere
Point, and client can be according to configuration, the state of oneself synchronous required type, rather than synchronous all types of state letters
Breath.Type can include subtype, i.e. the tissue of type is a tree, it is possible to understand that into directory tree.
In addition, the state storage of cluster is non-persistent, the machine once Centroid is delayed, the data in Centroid will lose
Lose, but do not influence the communication of application program and cluster.Although the machine of delaying of Centroid, is likely to result in the interim mistake of some data
Phase.But due to multiple client and synchronization presence, when Centroid recovers, the synchronization of state can be automatically performed again,
Centroid will also recover all data, including repair expired data.Client and Centroid all can be detected periodically
Internal status data, if it find that state is overtime, can be marked as expired, then be synchronized to Centroid or other clients
End.
