US 2026/0106684 A1 · STORAGE DEVICE, DATA COMMUNICATION METHOD, AND SYSTEM

Abstract

A storage device, a data communication method, and a system, related to the field of optical communication technologies. A network adapter in the storage device implements OTN encapsulation of data, so that an OTN frame to which the data is mapped can be generated without transmission and encapsulation of the data through a plurality of devices. This reduces transmission latency of the data from a memory to an optical transceiver, and improves data communication efficiency. In addition, because the data does not need to be processed through an Ethernet switch, a protocol stack used by the storage device to encapsulate the data into the OTN frame does not need to use an Ethernet protocol. This simplifies an encapsulation procedure required for generating the OTN frame, reduces an amount of data included in the OTN frame, and helps further improve the data communication efficiency.
