Data processing method and device, equipment and medium

The invention provides a data processing method which can be applied to the field of Internet of Things and the field of communication. The data processing method comprises the steps that in response to a monitored connection request of a target client side, connection with the target client side is established through asynchronous connection requests in a completion port, the number of the asynchronous connection requests is N, and N is larger than or equal to 2; detecting the state of the completion port by using the working thread to obtain a state detection result; creating a client management object under the condition that the state detection result represents that the establishment of the connection with the target client is completed; initializing the asynchronous connection request, and delivering the initialized asynchronous connection request to the completion port so as to ensure that N asynchronous connection requests are kept in the completion port; and when the TCP service monitoring is stopped
