Message processing method, hardware accelerator and network card

The embodiment of the invention provides a message processing method, a hardware accelerator and a network card. In the message processing method, when a received first cloud service message indicates a read operation response, a hardware accelerator analyzes the first cloud service message to obtain a message abstract and a message body; and sending the message digest to a network card processor, so that the network card processor performs inner-layer protocol processing and cloud service management and control based on the message digest, and sending the message body to a storage address of a cloud server. Furthermore, the hardware accelerator obtains sub-message elements by analyzing the sending message elements, requests each sub-message header and each sub-message body through the sub-message elements, and generates cyclic redundancy check of a second cloud service message to be sent through cyclic redundancy check of the message headers and cyclic redundancy check of the message bodies. According to the
