Title:
DATA MESSAGE TRANSMISSION METHOD, NETWORK DEVICE, CONTROL DEVICE, AND NETWORK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/214701
Kind Code:
A1
Abstract:
Provided in the present application are a data message transmission method, a network device, a control device, and a network system. In a data message transmission method, a network device receives a first data message transmitted by a first device, wherein a message header of the first data message comprises a first number tag sequence, a first position tag sequence, a first accumulation value, and a verification value; the network device obtains a second data message, wherein a message header of the second data message comprises a second number tag sequence, a second position tag sequence, a second accumulation value, and the verification value; and the network device transmits the second data message to a second device. The solution of the present application can verify an order of data messages passing through intermediate network devices over a path without the intermediate network devices needing to perform encryption and decryption, thus helping to alleviate the computational burden of the intermediate network devices.
