Abstract
A data transmission method is disclosed. A sending device obtains data transmission configuration information. The data transmission configuration information includes a network address of a receiving device and address information of to-be-transmitted data. The sending device reads the to-be-transmitted data from a data disk based on the address information, and sends a first data packet to the receiving device based on the network address of the receiving device. The receiving device obtains the first data packet, and stores first data included in the first data packet in a data disk of the receiving device.
Claims20
A data transmission method, wherein the method is applied to a sending device in a first data center, and the method comprises:
- obtaining data transmission configuration information, wherein the data transmission configuration information comprises a network address of a receiving device and address information of to-be-transmitted data, the address information indicates storage address information of the to-be-transmitted data in a data disk, the data disk is a data disk of the sending device, the to-be-transmitted data is data that needs to be transmitted by the first data center, and the receiving device belongs to a second data center;
- reading the to-be-transmitted data from the data disk of the sending device based on the address information;
- and
- sending a first data packet to the receiving device based on the network address of the receiving device, wherein the first data packet is obtained by encapsulating the to-be-transmitted data.
A data transmission method, wherein the method is applied to a receiving device in a second data center, and the method comprises:
- obtaining a first data packet sent by a sending device, wherein a payload of the first data packet comprises first data in to-be-transmitted data, and a packet header of the first data packet comprises an identifier of a data disk that stores the first data, and an offset of the first data;
- and
- storing the first data comprised in the first data packet in a data disk of the receiving device.
A sending device, wherein the sending device comprises a memory and a plurality of processors, the memory is configured to store a set of computer instructions, and the plurality of processors execute computer instructions to cause the sending device to:
- obtain data transmission configuration information, wherein the data transmission configuration information comprises a network address of a receiving device and address information of to-be-transmitted data, the address information indicates storage address information of the to-be-transmitted data in a data disk, the data disk is a data disk of the sending device, the to-be-transmitted data is data that needs to be transmitted by the first data center, and the receiving device belongs to a second data center;
- read the to-be-transmitted data from the data disk of the sending device based on the address information;
- and
- send a first data packet to the receiving device based on the network address of the receiving device, wherein the first data packet is obtained by encapsulating the to-be-transmitted data.
