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 generate label 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
The present invention relates to technical field of data transmission, relate in particular to a kind of method and system of transmitting data between heterogeneous different networks.
Background technology
At present, solve the process automation of point-to-point between two or more data sources under data source isomery, network isomerous environment, point-to-multipoint, a plurality of point-to-multipoints, the technology that need not the manual intervention transfer of data mainly contains following three kinds:
the first technical scheme is the intermediary transmission: intermediary shows as a kind of database program or a kind of file storage program, under this technology, if data source A will be to data source B the transmission of data, data source A need to be according to the Information Organization form (reference information form) of intermediary regulation, transfer data to intermediary, store appointed position into or be labeled as approximately by intermediary and store the optional position into after definite form, by data source B according to about definite form, obtain corresponding data to the intermediary storehouse, and be the own form of data source B with the reference information format conversion, if need to carry out the transmission of point-to-multipoint or a plurality of point-to-multipoints, implementation shows as the stack of said process.
the second technical scheme is the demons transmission: demons show as a kind of special guard's particular source, be responsible for the program of transfer of data, under this technology, if data source A will be to data source B the transmission of data, the demons of data source A (A keeps) must be completed according to configured in advance the positional information of demons (B keeps) of the data source B of (manually) and it sets up communication path (AB path), A keeps the data of receive data source A, being delivered to B by the AB path keeps, B garrison general's data are given data source B, the conversion of data format is responsible for by data source B self.
The third technical scheme is that intermediary adds demons combination transmission: in conjunction with the description of the first technical scheme and the second technical scheme, the intermediary form of expression is consistent with the first technical scheme, guard's object of demons becomes intermediary from data source, data transfer and the first technical scheme and the second technical scheme are similar, and difference is that the data transmission between different intermediarys is responsible for by demons.
These three kinds of technology have characteristics separately, also exist serious deficiency simultaneously.
although the implementation of the first technical scheme seems to have solved the data source isomery, point-to-point between two or more data sources under the network isomerous environment, point-to-multipoint, the process automation of a plurality of point-to-multipoints, need not the transfer of data of manual intervention, but this technology realizes requirement and must set up an intermediary, all data transmission procedures all rely on intermediary, show as a kind of radial star structure, the burden of intermediary is extremely heavy, increase along with data source quantity, efficiency of transmission can be how much levels and descend, and, owing to relating to data message, intermediary can't be supported redundancy scheme, and then on realizing, whole technology exists fatal single failure point, in case intermediate media lost efficacy, data transmission between data source will be limited to paralysis.
the implementation of the second technical scheme is because each data source all has specific demons, a plurality of demons are responsible for transfer of data, avoided to a certain extent this transmission pressure of similar intermediary to concentrate on the inadequate natural endowment at center, and a plurality of demons seem also to have disperseed the risk of single failure point, but, because needing pre-defined positional information, demons set up passage, therefore only be suitable for point-to-point transfer of data, can't realize the transfer of data of point-to-multipoint, simultaneously, depend on provider's privately owned agreement due to the realization of demons, transparent transmission between heterogeneous network can't be provided, necessary manual intervention, change the access rule between heterogeneous network.
Combination by dual mode on the implementation surface of the third technical scheme has utilized advantage separately, but identical due to realization mechanism, therefore do not have ability that its inborn shortcoming is improved and even eliminated, even a plurality of intermediarys, also still there is the increase along with data source quantity, efficiency of transmission can be the congenital shortcoming of how much level declines, responsible part for each intermediary still exists the single failure point, and the use of demons equally also can bring can not realizing of transparent transmission between heterogeneous network.
