Problems solved by technology

However, the data traffic in the upload direction and the download direction is often asymmetrical when the network actually works; for example, the use of most personal computers focuses on downloading rather than uploading, so the usage of network cables for downloading data is usually significantly greater than that of The amount of network cable used to upload data
Therefore, the above-mentioned symmetrical characteristics often cause the transmission direction on the Ethernet network that requires a large bandwidth to be congested due to insufficient line bandwidth; while the transmission direction that requires a small bandwidth has excess line bandwidth and is idle.
In view of this, the present invention provides an asymmetric Ethernet data transmission system to solve the above-mentioned problem of improper bandwidth allocation

Abstract

The invention discloses an Ethernet nonsymmetrical data transmitting system and method. With the help of a network card structure nonsymmetrical data transmitting system which can automatically switch transmitting modes and by using this system to change symmetry of Ethernet data transmission, it forms a nonsymmetrical data transmitting mechanism and further increases band width of Ethernet data transmission.

Description

technical field [0001] The present invention relates to a network data transmission system, in particular to an asymmetrical data transmission system of the Ethernet. Background technique [0002] With the rapid development of science and technology, the network has become an indispensable medium for information transmission in modern society. Among networks of various scales, LAN is widely used by general enterprises and even individuals because of its small range, high-quality transmission cables with fast transmission speed, and relatively cheap equipment. At present, the most common local area network technology is Ethernet (Ethernet). The elements of an Ethernet network include an Ethernet card (Ethernet card) and a network connection device, wherein the connection device uses many different forms of cables (cable). The data transmission of the known Ethernet has a symmetrical characteristic, which means that the same bandwidth is used in the process of uploading and d...
