[0051] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific implementations are now described in detail.
[0052] VXLAN uses plain text to transmit data. There are certain security risks for using VXLAN to transmit data across regions. Therefore, it is necessary to provide a method that supports encrypted data transmission in VXLAN mode.
[0053] Such as figure 1 As shown, the gateway VXLAN can choose the encrypted data transmission method, and the VXLAN local end negotiation can choose encrypted data transmission. Before the local end that supports VXLAN encrypted data transmission sends data to the opposite end, it first tries to negotiate the encryption option, and starts data encryption after the negotiation is successful. transmission, including the following steps:
[0054] 1) The VXLAN local end sends an optional encryption request message to the peer end;
[0055] 2) The VXLAN local end waits for ...
