Optical packet transmission method and device, optical packet processing method, and optical switching device

摘要

Embodiments of the present invention provide an optical packet sending method and device, an optical packet processing method, and an optical switching device, where the sending device includes: a processor, configured to obtain a first optical packet payload and/or a third optical label, and obtain a second optical label and a second optical packet payload corresponding to the second optical label; and an exporter, configured to send to an optical switching device, within a guard time between a moment for sending the second optical label and a moment for sending the second optical packet payload, the third optical label and/or the first optical packet payload that are/is obtained by the processor, so that the optical switching device performs, according to the third optical label, switch processing on a third optical packet payload corresponding to the third optical label, and/or the optical switching device performs switch processing on the first optical packet payload according to a first optical label corresponding to the first optical packet payload. Technical solutions provided in the embodiments of the present invention are used to improve transmission link usage of an optical label and an optical packet payload.
