Optimization method for large-scale concurrent communication

The invention discloses an optimization method for large-scale concurrent communication. The method comprises the following steps: S1, enabling a sender to initiate a sending request to a receiver, and setting an initial value of a counter; S2, after the receiver receives the sending request from the sender, matching related receiving request information and responds to destination address information to the sender; S3, after the sender receives the request response from the receiver, delivering the first n split transmission requests; S4, if it is detected that a certain transmission requestis completed, subtracting 1 from the value of the completion counter, and judging whether the value of the current completion counter is 0 or not; if yes, delivering a completion notification to the sender, and otherwise, continuing to supplement a subsequent transmission request; S5, enabling the receiver to receive the completion notification from the receiver and set that the receiving operation is completed.
