Embodiment Construction
[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0036] Embodiments of the present invention provide a method for data synchronization, such as figure 1 shown, including:
[0037] Step 101: The intermediate data node receives a data synchronization message sent by a previous data node, and the data synchronization message includes a data synchronization identifier and data to be synchronized.
[0038] In a process of data synchronization, there may be one or more intermediate data nodes; the intermediate data no...

The invention provides a data synchronization method and system, an immediate data node and a terminal data node. The data synchronization method comprises the steps of receiving a data synchronization message transmitted by a previous data node, wherein the data synchronization message includes a data synchronization identifier and data to be synchronized; carrying out data synchronization and recording a synchronization processing state based on the data synchronization identifier and the data to be synchronized, wherein the synchronization processing state is associated with the data synchronization identifier; transmitting the data synchronization message to a next data node so that the next data node carries out the data synchronization and records the synchronization processing state based on the data synchronization message; and receiving a feedback message transmitted by the next data node, changing the synchronization processing state associated with the data synchronization identifier and transmitting the feedback message to the previous data node; and thus, the data consistency of multiple nodes during data synchronization is ensured.
Description
technical field [0001] The invention belongs to the technical field of network communication, and relates to a data synchronization method, system, intermediate data node and termination data node. Background technique [0002] In the telecommunications network, since user data or service subscription data needs to be shared among multiple systems, more and more isolated data in previously isolated networks are shared among multiple systems. Therefore, a new customer and user data will need to be synchronized among multiple systems, so the requirements for data consistency are relatively high. For data interaction between traditional systems, if data consistency needs to be ensured, data subscription and notification mechanisms can be used, and notifications can be broadcasted to achieve data synchronization. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] When synchroni...
