Embodiment Construction
[0048] Embodiments of the present invention provide a data processing method for an optical transport network, related equipment and a system.
[0049]Optical burst switching or optical burst slot switching is a novel all-optical switching technology with sub-wavelength granularity. Its core idea is to divide a wavelength into many sub-wavelength optical time slots, and encapsulate and map service data into each optical time slot. At the intermediate nodes of the network, optical signals are switched through all-optical methods such as all-optical switching arrays. Simply understood, the all-optical switching array is an "optical switching chip", which corresponds to an "electrical switching chip" that can directly switch optical burst packets. Optical signals are exchanged through an all-optical switching array and other all-optical methods, which saves the optical-electrical-optical conversion of intermediate nodes and a large amount of electrical signal processing. The da...
