Abstract

The invention provides data transmission methods and devices, relates to the field of communication and is used for improving business transmission quality and improving network resource utilization efficiency. A method comprises the steps that an SDN (Software Defined Network) controller obtains first data traffic information between a first transmission node and a second transmission node; if the first data traffic information satisfies a first preset condition, the SDN controller determines a bandwidth requirement of a transmission path according to the first data traffic information, wherein the transmission path is used for transmitting target data, a source access node corresponding to the target data is the first transmission node, and a destination access node corresponding to thetarget data is the second transmission node; and the SDN controller establishes the transmission path between the first transmission node and the second transmission node according to the bandwidth requirement of the transmission path. According to the business transmission method provided by the invention, bandwidth resource allocation is carried out based on the transmission path, the business transmission quality can be improved, and the network resource utilization efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data transmission method and device. Background technique [0002] With the widespread application of new technologies such as cloud computing, the Internet of Things, and 5G, global Internet traffic is showing explosive growth, and the scale of the Internet is also expanding. According to the forecast data of Cisco Global Cloud Index, the total global Internet traffic will increase to 3.064ZB in 2021, which will be 3.07 times the total traffic (0.998ZB) in 2016, with a compound growth rate of 25.2%. [0003] With the rapid growth of network traffic, various new services and applications are constantly emerging. Compared with traditional applications, these services and applications have higher requirements on network performance. For example, services such as industrial automation, unmanned driving, and mobile medical care require latency as low as 1ms an...
