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...

Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0027] figure 1 It is a schematic structural diagram of a data transmission system between heterogeneous and different networks in a specific embodiment of the present invention. Such as figure 1 As shown, the data transmission system includes multiple data sources and multiple location databases. These data sources are distributed in heterogeneous heterogeneous networks and are respectively connected to the location databases. The data sources generate location packets and send them to the location databases, and generate tag data packets to send Establish a transparent data flow channel for the location library and other databases for data transmission. The location library maintains the location tag index and obtains the address information, forwarding protocol, and information organization form...
