Further, encryption of the processing module to data message uses RSA asymmetric arithmetics, and Crypted password uses
ASE algorithms, length are 256.
Further, wired or wireless connection between the data uplink port of described two transmission equipments.
The utility model is also achieved through the following technical solutions：
A kind of network topology structure, including first network and multiple second networks, first network and each second network it
Between be provided with transparent transmission device, make to be respectively formed Bidirectional transparent transmission passage between first network and each second network.
The utility model has the advantages that：
1st, transceiver module of the present utility model receives all data messages that data downstream port is reached in present networks, data
Message is sent after processing module TCP packages and encryption by data uplink port, through Bidirectional transparent transmission channel transfer to it is another
The data uplink port of the transmission equipment of one network connection；Data uplink port receives another network through Bidirectional transparent transmission channel transfer
Data message, after data message is decrypted through data processing module, TCP is unpacked, from transceiver module by data downstream port to
Present networks are sent；Transmission equipment in two networks can transmit the data message each collected as former state to other side, make two
Individual network merges into a unified network, and original resource can be shared in two networks, and communication performance is high, and deployment is simple,
It is compatible strong.
2nd, by setting transparent transmission device first network is respectively formed Bidirectional transparent transmission passage between multiple second networks respectively,
So that more heterogeneous networks merge into a big network, and without the interaction of data message between each second network, because
This can than multigroup point-to-point connection in a manner of merging big network more bandwidth-saving, so as to reduce cost, and dispose it is simple, just
In management.
