Embodiment 1
[0028] Such as figure 1 and figure 2 Shown, the data transmission method based on TCP of the present invention comprises steps:
[0029] S100: Receive a message segment.
[0030] S200: Determine whether the received message segment is a message segment waiting to be received, if yes, enter the fast processing flow, otherwise enter the slow processing flow.
[0031] The rapid processing flow of this embodiment includes the following steps:
[0032] S300: Judging whether there is data in the received message segment, that is, judging whether the payload data length of the message segment is zero, if it is zero, it means that there is no data in the message segment, and if it is not zero, it means that the message segment There is data in it. When there is data, go to step S301; if there is no data, go to step S302.
[0033] S301: Determine whether the transmission sequence of the message segment is correct and whether the cache can accommodate the data in the message segme...
