The invention discloses a cross-data center RDMA network congestion control method and device based on in-band telemetering, and belongs to the technical field of network transmission control. The method comprises the following steps: sending a first cross-data center flow to an upstream DCI switch at an initial rate; according to a Switch-INT message returned by an upstream DCI switch, a first fair rate is calculated, a second cross-data center flow is sent to the upstream DCI switch at the first fair rate, an ACK message of a downstream data center responding to the first cross-data center flow is obtained, and the ACK message comprises a suggested rate; and generating a final rate in combination with the first fair rate and the suggested rate, and sending a third cross-data center flow to an upstream DCI switch at the final rate. According to the method, the network sensing capability of the cross-data center flow can be improved, the fairness of the flow in the data center and the cross-data center flow is improved, and the transmission delay of the datagram is optimized.

The present invention discloses a data transmission method for an industrial Internet of Things realized by multi-network networking. The present invention relates to the technical field of multi-network networking and solves the problem that failure to analyze the transmission protocols between different network networkings will result in a large interaction delay between two sub-devices during interaction. The present invention determines the variance between multiple standard average speeds corresponding to different sub-devices among multiple formats to be converted based on different standard average speeds corresponding to different sub-devices, selects a minimum value from the multiple variances, and thereby locks the corresponding standard format. When the data between the corresponding pending networks are subsequently converted, the rate differences between the conversion rates of the sub-devices between the different pending networks are all in the lowest state. Therefore, when the different sub-devices subsequently perform data interaction, the corresponding transmission delay is reduced to the minimum, thereby ensuring that the data between the multi-network networkings can achieve a better transmission rate during the transmission process, and the transmission delay can be fully guaranteed.
