Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] The following starts with figure 1 The system architecture diagram of the transmission system for preventing data loss mentioned in the present invention illustrates the system operation of the present invention. Such as figure 1 As shown, the system of the present invention includes a transmitting end 100a and a receiving end 100b.

[0019] The transmitting end 100a is responsible for encapsulating the target data 310 to be transmitted to the receiving end 100b into a packet 300 containing header information 320, wherein the header information 320 at least includes transmission identification data, and the transmission identification data is used to provide the receiving end 100b The basis for judging whether the target data 310 has been received, generally speaking, the transmission identification data is the serial number generated ...

Abstract

The invention discloses a delivery system, a device and a method thereof for preventing data loss, packets packaging same target data are transmitted to a receiving end through a transmitting end via a first channel and a second channel, the receiving end can discard the repeated packets after determining that the packets have been received, and process the packets after determining that the packets have not been received, thereby achieving the technical effect of reducing the probability of the data loss.

Description

technical field [0001] The invention relates to a transmission system, device and method for preventing data loss. Background technique [0002] WLAN is a network that uses radio as the data transmission medium. It usually uses cables as the backbone, and the backbone is connected to multiple wireless devices. Users of WLAN need to use wireless devices to connect to another connection. To the backbone wireless device to use the wireless network, the data transfer between the two wireless devices can be carried out directly (ad hoc), or it can be coordinated at the base station (BaseStation, BS) or access point (Access Point, AP) next. WLAN has been widely used in schools, airports, and other public areas. [0003] Since the wireless area network uses radio to transmit data, the data is very susceptible to interference from the external environment during the transmission process, resulting in data damage. Therefore, in the use environment of the wireless area network, a da...
