Problems solved by technology

[0008] 1) The equipment in the system is complicated, and the message program is cumbersome
[0009] 2) The number of servers in the system needs to be set in advance. When the dynamic change of the number of servers participating in the system exceeds the set value, the system will not work normally

Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] Such as figure 1 As shown, it describes a distributed system consisting of four servers. The data on these four servers are consistent. Users can submit data modification requests to any server, that is, for users, there is no need to distinguish specific servers, and they think that all servers belonging to the system are indistinguishable.

[0038] One, the characteristic that the distributed real-time synchronous network system of the present invention possesses is:

[0039] 1) The system is connected by several servers through the network.

[0040] 2) At any time, a new server may join the system, or a server in the system may exit the system.

[0041] 3) The data of any server in the system is consistent and synchronized in real time.

[0042] Two, such as figure 2 , 3 , Shown in 4, build the key technology of system of the present invention as follows: ...

Abstract

The invention discloses a distributed type real-time synchronizing network system simple in structure and a data annunciating method of the distributed type real-time synchronizing network system, and all servers in the system can have the same data. The data stored in all the servers in the system are the same, and different priorities are given to the servers. The method comprises the steps that (1), each server annunciates the priority of the server regularly and transfers priority announcements to other neighbor servers except for the servers sending the priority announcements after receiving the priorities announcements of the neighbor servers; (2), the servers with the low priorities transmit the request information provided by user terminals of the servers with the low priorities to the server with the highest priority, or transfer the request information to the server with the highest priority through the adjacent servers; (3), after the server with the highest priority puts request information on records, the recorded information is transferred to the servers of the system through the adjacent servers, and all the servers keep the same stored data.

Description

technical field [0001] The invention relates to a distributed system based on the Internet, in particular to a distributed real-time synchronous network system and a method for notifying data thereof. Background technique [0002] With the rapid development of Internet technology, it has become an indispensable tool in people's life, and the data sharing system has become a basic function in various Internet applications. In the data sharing system, the data is no longer independently dispersed in each server, but the unified data maintained by multiple servers; any server can request to modify the data, and any modification of the data requires It is reflected in every server in the system in real time. In this mode of operation, how to ensure real-time synchronization of data from multiple servers without significantly affecting user experience has become an unavoidable technical problem for distributed systems. [0003] Currently, widely used distributed algorithms incl...
