Embodiment Construction
[0041] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.
[0042] Such as image 3 with Figure 4 As shown, the identity-based cross-network tunnel transmission method includes the following steps:
[0043] S1. Configuring additional gateway units with private tunneling protocols in different network domains;
[0044] S2. Generate unique identities for end users in the same network domain through the additional gateway unit, map and store the real IP and identity of the end user ...

The invention discloses a cross-network tunnel transmission method based on an identity mark, which includes the following steps: S1, configuring an additional gateway unit; S2, generating a unique identity mark; S3, querying the identity mark corresponding to the communication source IP; S4, querying Whether the communication destination IP is online; S5, returning the query result; S6, performing private tunnel protocol encapsulation and routing to the extra gateway unit of the source network domain; S7, transmitting the encapsulated message to the extra gateway unit of the destination network domain; S8, The received message is transmitted to the transmission agent device of the destination network domain; S9, perform untunnel encapsulation, and query the real IP of the receiver according to the communication destination IP of the decapsulated message, and select a route to forward, and complete the cross-network Tunneling. This method solves the routing addressing problem of the same network segment or even the same IP terminal in different network domains, so that the IP address planning in one network domain is not affected by the address planning of other network systems.
Description
technical field [0001] The invention relates to the communication field, in particular to an identification-based cross-network tunnel transmission method. Background technique [0002] In the existing network environment, taking text and electronic applications as an example, the information exchange process between users in the same network domain is as follows: figure 1 As shown, the sender first sends the information to the sender's transfer agent, and the receiver of the information is identified by name. The sender's transfer agent obtains the network address of the receiver's transfer agent through directory resolution, and then the sender's transfer agent sends the user information to the receiver. The transfer agent, and then the transfer agent of the receiving party hands over the information to the information receiver, and the information exchange process ends. Such as figure 2 As shown, when the information sender and receiver belong to different network syst...
