Virtual network disk device based on embedded system technology and application of virtual network disk device

Abstract

The invention provides a virtual network disk device based on an embedded system technology and the application of the virtual network disk device. The virtual network disk device at least comprises a virtual module, a plurality of data transmission modules and a multi-channel mixed transmission processing module. The virtual module is used for virtualizing the network disk device which the virtual module belongs to into a device capable of exchanging data with a user device when the virtual network disk device which the virtual module belongs to is connected with the user device. Each data transmission module carries out data transmission with a multi-channel server based on at least one data transmission mode, and data transmission modes adopted in the data transmission modules are different. The multi-channel mixed transmission processing module is used for determining data to be transmitted based on the data exchange with the user device and splitting the data to be transmitted into corresponding subdata based on the available data transmission modules, and the available data transmission modules transmit the corresponding subdata to the multi-channel server to achieve multi-channel mixed transmission. Accordingly, the user data can be flexibly and rapidly uploaded conveniently.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a virtual network disk device and application based on embedded system technology. Background technique [0002] Wide area network (WAN, Wide Area Network), also known as long haul network, is a network that spans a large physical range (covering from tens of kilometers to thousands of kilometers). For example, ordinary users are extremely The familiar Internet is the largest wide area network in the world, which can connect multiple cities or countries, or span several continents and provide long-distance communication, forming an international long-distance network. The communication subnet of the WAN can use the public packet switching network, satellite communication network and wireless packet switching network to interconnect LANs or computer systems distributed in different regions to achieve the purpose of resource sharing. [0003] Data transmission based on WAN is curr...

Problems solved by technology

However, there are many inconveniences whether data is transmitted in a wired or wireless way. For example, if the wired network is used for transmission, the transmission location is fixed and cannot be moved; if the wireless network is used for transmission, the transmission bandwidth is slow and the transmission speed Instability and other disadvantages

Since there is currently no solution that can bundle multiple transmission methods in the market, users usually use a personal computer combined with a single network for data transmission based on computer files, and then use FTP, QQ and other transmission tools for transmission. Data transmission is extremely inconvenient
