However, when the value of the public state is cached in the device, different devices can maintain the stored public state in different ways, so, in the whole system, if there are inconsistent public state values ​​between different devices , which may cause several devices to fail when interacting with each other

Embodiment Construction

[0016] FIG. 1 is a schematic diagram showing a network architecture of a state synchronization system 10 according to an embodiment of the present invention. Preferably, the network architecture includes personal computers 11 , 13 , 15 , 17 and 19 . Wherein, the personal computers 11 , 13 , 15 , 17 and 19 can be connected to each other in a wired-connection, wireless or a hybrid wired-connection and wireless manner. Those skilled in the art know that the connection between the personal computers 11, 13, 15, 17 and 19 may have to go through multiple intermediary nodes, such as wireless access points (access points), base stations (base stations), hubs (hub), bridge (bridge), router (router) or other intermediary nodes used to handle network communication. The state synchronization system 10 adopts a publisher-subscriber model or a push model for state change notification. In detail, the personal computer 11 advertises the provided services on the network, so that the personal...

Abstract

The invention provides a state synchronize method, executed by a first electric device, while the local memory space of the first electric device stores a first service state value. The method comprises that when the first electric device not receives the event information not treated, judging if the first service state value stored in the local memory space is overdue, and when the value is overdue, sending a request to the second electric device to obtain a second service state value, to be stored in the local memory space. The first electric device is connected with network all the time, and the information of non-treated event can bear new service state value.

Description

technical field [0001] The invention relates to an event synchronization technology, in particular to a state synchronization device and method in a small distributed service environment. Background technique [0002] Devices in a distributed environment (especially for event-driven service management systems) can share common states to achieve service coordination and collaboration. Generally speaking, in the service management system, notification of service status changes can be performed in an asynchronous manner, that is, the server (or central management platform) notifies all devices of the changed status one by one. However, when the value of the common state is stored (cache) in the device, different devices can maintain the stored public state in different ways, so, in the whole system, if the value of the common state is inconsistent among different devices , which may cause several devices to fail when interacting with each other. Therefore, there is a need for...
