Embodiment Construction

[0084] figure 1 A schematic flowchart of a data transmission method 100 according to an embodiment of the present invention described from the perspective of the sending end device is shown, as shown in figure 1 As shown, the method 100 includes:

[0085] S110. The sending end device acquires first data, where the first data is data sent by the first Ethernet device to the second Ethernet device.

[0086] In implementation, the first data may include a MAC data frame or an Internet Protocol IP data packet at the medium access control layer;

[0087] S120. Using a scrambler, perform first scrambling processing on the first data to generate second data, wherein the scrambler starts the first scrambling processing and completes the first scrambling processing , in the preset first initial state;

[0088] S130. According to the second data, generate an optical data packet including an optical data frame, wherein the optical data frame includes a first preamble field, a data sta...

Abstract

A data transmission method, device and system, which can achieve stable and reliable data transmission between Ethernet devices through an optical switching device. The method comprises: a sending end device acquiring first data; conducting first scrambling processing on the first data by a scrambler, so as to generate second data; according to the second data, generating an optical data package comprising an optical data frame, wherein the optical data frame comprises a first lead code field; sending an optical signal which bears the optical data package to an optical switching device, thereby facilitating the optical switching device in switching the optical signal, so as to send the optical data frame to a second Ethernet device. By adding the lead code in front of the second data, the optical switching device and a receiving end device can complete the recovery adjustment on a burst signal before the second data arrives through the lead code, and the Ethernet device which can only identify a continuous signal can be prevented from generating a reception error.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly, to a method, device and system for transmitting data. Background technique [0002] Ethernet (Ethernet) is a computer local area network networking technology. The existing technical standards of the Ethernet stipulate the content of the connection including the physical layer, the electrical signal and the medium access control layer (MAC, Medium Access Control) protocol. Ethernet has been developed to a transmission rate of 100GE, and is currently the most widely used LAN technology. Ethernet cards can work in two modes: half-duplex and full-duplex. Half-duplex transmission mode realizes Ethernet carrier sense multiple access conflict detection. The traditional shared local area network (LAN, Local Area Network) works under half-duplex, and can only transmit data in one direction at the same time. When data is transmitted in both directions at the same time, colli...
