Title:
OPTICAL SWITCH AND DATA COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/017325
Kind Code:
A1
Abstract:
Provided in the present application are an optical switch and a data communication system. Each switching link in the optical switch in the present application is provided with a cache group. For any switching link, if the wavelengths of at least two optical packets that need to be output via the switching link in one slot are the same, optical packets, other than one of the optical packets, can be cached in the cache group in the switching link, and the one of the optical packets is output in the slot; and in a subsequent slot, the other optical packets cached in the cache group are scheduled and then output, such that a conflict can be prevented. In addition, the structure of the optical switch in the present application can support FFQ scheduling on optical packets, and FFQ retrieval can be ideal scheduling based on a GPS, such that a broadband guarantee can be achieved, for example, the throughput of the optical switch for the switching of the optical packets can be improved, thereby improving the quality of the optical switch for the switching of the optical packets, and obtaining a quality-of-service guarantee.
