This disclosure proposes a high-concurrency data processing method, apparatus, and storage medium based on Ethernet / IP. The method includes: receiving message data sent by multiple node devices, sequentially caching the message data into a first message queue in the form of data response events, assigning an event handler component to each data response event in the first message queue, processing the assigned data response event based on a pre-configured CIP object model to obtain target data, and storing the target data in a data storage module. This enables various node devices to communicate using the Ethernet / IP protocol and process data response events separately using a CIP object model constructed with unified rules, thereby achieving data interconnection and interoperability.
