DATA TRANSMISSION METHOD, APPARATUS, AND SYSTEM

摘要

A data transmission method, apparatus, and system can implement stable and reliable data transmission between Ethernet devices by using an optical switching device. The method includes: acquiring, by a transmit end device, first data; performing first scrambling processing on the first data by using a scrambler, so as to generate second data; generating, according to the second data, an optical data packet that includes an optical data frame, where the optical data frame includes a field of a first preamble; and sending an optical signal that carries the optical data packet to a optical switching device, so that the optical switching device performs switching processing on the optical signal, so as to send the optical data frame to a second Ethernet device.

1. A data transmission method, comprising:
acquiring, by a transmit end device, first data, wherein the first data is data to be sent by a first Ethernet device to a second Ethernet device; performing first scrambling processing on the first data by using a scrambler, so as to generate second data; generating, according to the second data, an optical data packet comprising an optical data frame, wherein the optical data frame comprises a field of a first preamble, a data start field, a data field, and a data end field, and wherein the field of the first preamble is used to carry the first preamble, a length of the first preamble is greater than or equal to a first preset value, the data field is used to carry the second data, the data start field is used to carry a data start character, the data start character is used to identify a start of the second data, the data end field is used to carry a data end character, and the data end character is used to identify an end of the second data; and sending an optical signal that carries the optical data packet to an optical switching device, so that the optical switching device performs switching processing on the optical signal, so as to send the optical data frame to the second Ethernet device.
