Problems solved by technology

However, when the value of the common state is cached in the device, different devices can maintain the common state of the cache in different ways, so different devices may have inconsistent values ​​of the common state, thereby causing service Situations where integration fails

Embodiment Construction

[0037]FIG. 1 shows a schematic diagram of a network structure of a state synchronization system 10 according to an embodiment of the present invention. In a preferred case, this network structure includes personal computers 11, 13, 15, 17, and 19. Among them, the personal computers 11, 13, 15, 17 and 19 can be connected to each other in a wired-connection, wireless or hybrid physical and wireless manner. Those who are familiar with this art know that the connection between personal computers 11, 13, 15, 17 and 19 may require multiple intermediary nodes, such as wireless access points, base stations, and hubs. , Bridges, routers or other intermediary nodes used to process network communications. The state synchronization system 10 adopts a publisher-subscriber model or a push model to perform state change notifications. In detail, the personal computer 11 advertises the services provided on the network, so that the personal computers 13, 15, 17, and 19 can discover and subscribe to...

Abstract

Synch state method includes acquiring the first service state edition identification code stored in the first electronic device local buffer cache space; obtaining the second service state edition identification code stored in each second electronic device by inquiring a plurality of second electronic devices; judge whether each second service sate edition identification code is older than the first service state edition identification code; when the second service sate edition identification code is older than the first service state edition identification code, transmit the forward update request to the second electronic device stored with older second service state edition identification code and facilitate the second electronic device start upward examination procedure to update the older second service state edition identification code. The first and the second service state identification code are generated by the third electronic device service. The first, second and third electronic device form a tree structure of event propagation. The third electronic device is positioned on the root node of the tree structure. The first and the second electronic device are positioned on the leaf node of the tree structure.

Description

Technical field [0001] This invention relates to an event synchronization technology, in particular to a state synchronization system and method in a super-large distributed service environment. Background technique [0002] Devices in a distributed environment (especially an event-driven service management system) can share common states to achieve the purpose of service coordination and collaboration. Generally speaking, in a service management system, the notification of service status changes can be done in an asynchronous manner, that is, a service (or a central management platform) notifies the device of all changed status one by one. However, when the value of the common state is cached in the device, different devices can maintain the common state of the cache in different ways. Therefore, different devices may have inconsistent values ​​of the common state, resulting in services Circumstances where integration fails. Therefore, there is a need for a state synchronization...
