Title: Communication system between computers
Inventor: WATABE NOBUO
IPC: G06F13/00
Filed: 1983-01-31
Abstract: PURPOSE:To make high-speed data transfer possible and limit the number of an unprocessed bucket by making a response as long as a margin is left in a buffer. CONSTITUTION:In case of transfer from an application process 1 to an application process 4, the application process 1 requests transmission to a communication process and does not request the next transmission before receiving the response to the preceding transmission request from the communication process 2. When the communication process 2 receives the transmission request from the process 1, the process 2 returns the response to the process 1 immediately if a margin is left in the buffer. Since the response is returned quickly, the prefetch of a transmission-side application program is possible to make the high-speed data transfer possible.
