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

Abstract

The invention provides a network data transmission method applied to transmission between communication devices. The network data transmission method comprises the steps of transmitting network data from a communication device which serves as a source terminal to a communication device which serves as a target terminal, and obtaining M first data transmission paths between the source terminal andthe target terminal; sequencing the M first data transmission paths according to the length of the transmission path from long to short, and then obtaining N second data transmission paths from the first data transmission paths in the sequence sequentially from low to high; distributing data flow corresponding to data transmission quality for each second data transmission path based on to-be-transmitted amount of network data; and transmitting the distributed data flow to the target terminal by each second data transmission path. Different transmission service demands are satisfied, and transmission efficiency of the network data is improved.

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...
