Abstract

The embodiment of the invention provides a data transmission method and device, and the method comprises the steps: obtaining a plurality of port sets of a first gateway when data enters the first gateway, and each port set comprises at least one transmitting port; and obtaining the respective delay level of each port set, and obtaining the priority of the data. And determining a target sending port in the plurality of port sets according to the respective delay level of each port set, the priority of the data and the data. And sending data to the second gateway through the target sending port. According to the technical scheme of the invention, the method comprises the steps: obtaining the time delay levels of a plurality of port sets of a first gateway, determining the priority of data needing to be forwarded by the first gateway, carrying out the matching according to the time delay levels and the priority, and determining a target sending port in the plurality of port sets. Therefore, the time delay stability of data transmission can be effectively improved.

Description

technical field [0001] The embodiments of the present application relate to communication technologies, and in particular, to a data transmission method and device. Background technique [0002] Virtual Extensible Local Area Network (Vxlan) is a network virtualization technology that can improve the scalability of large-scale cloud computing deployment. [0003] At present, gateways are usually used to encapsulate Vxlan in cloud networks for cross-computer room communication. For the data between two Vxlan gateways, only the source UDP port is changed. In the prior art, when selecting the UDP source port, the hash calculation is usually performed according to the inner quintuple of the data to be transmitted to select A UDP source port for data forwarding. [0004] However, the UDP source port selected only according to the inner quintuple of the message may not necessarily meet the delay requirement of data transmission, which will lead to poor stability of the delay of d...
