Embodiment Construction

[0031] Embodiments and examples of the present invention will be described in detail below with reference to the drawings.

[0032] The scope of applicability of the present invention will become apparent from the detailed description given below. It should be understood, however, that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given for purposes of illustration only.

[0033] In the network environment, the addresses of all nodes are known, and the number of nodes is also known. The network environment can be TCP / IP or other self-defined self-organizing network. In an unstable network, any node may be insecure and fail. For example, in a traditional server environment, the network between the terminal and the server may be disconnected, so that synchronization between the terminal and the server cannot be performed, resulting in a system that may not function normally.

Abstract

The present application discloses a method and device for synchronizing information without a center, wherein the method includes: in response to a computing device accessing the network, broadcasting a request for querying the unique version number of the information in the network; Each computing device in the network, in response to receiving the request, determines whether it has the information recorded; each computing device in all other computing devices in the network, in response to having the information recorded, broadcasts within the network that it records the information The information is in response; the computing device broadcasting the request selects one of the responding computing devices as a synchronization object; and the information is synchronized between the selected synchronization object and the computing device broadcasting the request. The invention can realize the synchronization of information without a center, and guarantee that the failure of any node will not affect the operation of the system to the greatest extent.

Description

technical field [0001] The present application relates to the field of digital information transmission, in particular to a method for synchronizing information without a center and a device for realizing the method. Background technique [0002] The current information synchronization is mainly based on the server environment, and the amount of synchronized data is large, which is not suitable for ad hoc networks or similar micro-networks. [0003] However, in a low-bandwidth and unstable network environment, any node may be insecure and may fail. How to achieve low-load data synchronization under such a network is an urgent problem to be solved. Contents of the invention [0004] The invention provides a method and device for synchronizing information without a center, which can realize the synchronization of information without a central server, so that the realization of any node will not affect the operation of the system. [0005] In order to solve the above techni...
