Method and system for transmitting data between heterogeneous different networks

Abstract

The invention discloses a method and a system for transmitting data between heterogeneous different networks. A plurality of data sources are positioned in the heterogeneous different networks, and each data source generates a position package to be sent to a position base; the position base compares update positions in the position packages to determine whether position label information, address information and the like are re-set up or updated or not and maintain position label indexes; when initial data sources request data to target data sources, the initial data sources firstly generatelabel data packages to be sent to position bases, and the label data package comprises position label information with objective marking as target data sources; the position bases read the objective markings and obtains the address information of the target data sources and the like through the position label indexes; and transparent data flow channels between the initial data sources and the target data sources are set up to carry out data transmission. With the technical scheme of the invention, the data transmission of automatic point to point, point-multipoint, multipoint-point, and multipoint-multipoint without human intervention between a plurality of data sources in the heterogeneous environment of heterogeneous different networks can be realized.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a method and system for data transmission between heterogeneous networks. Background technique [0002] At present, the technologies that solve the process automation of point-to-point, point-to-multipoint, and multiple point-to-multipoint between two or more data sources in heterogeneous data sources and network heterogeneous environments, without manual intervention, mainly include the following three technologies: kind: [0003] The first technical solution is intermediary transfer: the intermediary is represented as a database program or a file storage program. Under this technology, if data source A wants to transfer data to data source B, data source A needs to follow the According to the specified information organization form (standard information format), the data is transmitted to the intermediary, and the intermediary stores it in the agreed position...

Problems solved by technology

[0007] Although the implementation of the first technical solution seems to solve the heterogeneity of data sources, the process automation of point-to-point, point-to-multipoint, and multiple point-to-multipoint between two or more data sources in a heterogeneous network environment does not require Manually intervened data transmission, but this technical implementation requires the establishment of an intermediary. All data transmission processes rely on the intermediary, which is represented as a radial star structure. The burden of the intermediary is extremely heavy. With the data source As the number increases, the transmission efficiency will drop geometrically. Moreover, due to the data information involved, the intermediary cannot support the redundancy mechanism, and there is a fatal single point of failure in the entire technical implementation. Once the intermediary fails, the data source Data delivery will be limited to paralysis

[0008] The implementation of the second technical solution is because each data source has a specific daemon program, and multiple daemon programs are responsible for data transmission, which avoids to a certain extent the congenital deficiency th
