Communication method with attaching identifiers to receive request and transmit request
 In a method of increasing the network use efficiency of computer communication and reducing the limitation of byte stream in a transmit/receive request, a virtual circuit is established between protocol modules such as applications for providing the communication function between software to mate one transmit request with one receive request. By returning an acknowledgement in a unit of request, any vain acknowledgement can be avoided and even in the case of asynchronous transmission/reception, a request which is completed in transmission/reception can be ended immediately, thus permitting efficient data transfer. Even when the transmit request length and the receive request length differ from each other, reliable communication of a request having a smaller request length can be ensured between mating transmit and receive requests. Further, in the case of synchronous transmission/reception, by copying only the latter half of a transmission buffer and returning a virtual ACK to the transmitting side when reception of the former half ends, the acknowledgement need not be waited for, thus permitting efficient data transfer.
