A method of network data transmission

Abstract

The present invention provides a network data transmission method, which is applied to the transmission between communication devices. Network data is sent from a communication device serving as a source terminal to a communication device serving as a target terminal, wherein, between the source terminal and the target terminal, Obtain M first data transmission paths; sort the M first data transmission paths according to the length of the transmission paths from low to high, and then obtain N ones from low to high according to the first data transmission paths in the sorting order as the second data Transmission path, wherein M>N; in the N second data transmission paths, obtain the data transmission quality of each second data transmission path; assign each second data transmission path to it according to the amount of network data to be sent The data traffic corresponding to the data transmission quality; each second data transmission path sends the allocated data traffic to the target terminal at the same time. It satisfies different transmission service requirements and improves network data transmission efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a network data transmission method. Background technique [0002] In order to cope with the ever-increasing and massive real-time communication demands of the mobile Internet, many companies and institutions have developed software-defined virtualized network technologies and more efficient transmission technologies, that is, SDN technology (Software Defined Network (SDN) , is a new innovative network architecture of the Emulex network and an implementation of network virtualization. Its core technology, OpenFlow, separates the control plane of network equipment from the data plane, thereby realizing flexible control of network traffic and making the network as a Pipelines become more intelligent.) Traditional QoS management technologies for network transmission mainly include methods such as quality classification and quality reservation. [0003] For example, LTE...

Problems solved by technology

The TCP design is applied to wired networks, and limited networks are generally not easy to lose packets. Therefore, TCP judges congestion based on the detected packet loss rate. According to the exponential back-off mechanism of TCP’s congestion window, TCP’s The transmission delay will be greatly increased

[0011] But in fact, the packet loss of the wireless network is caused by various factors such as wireless signal degradation, occlusion, switching, etc. The packet loss is not directly related to the congestion, so a new congestion control mechanism is needed to solve the efficiency problem of TCP
