COMMUNICATION DEVICE, ITS CONTROL METHOD, COMMUNICATION SYSTEM, AND CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To quickly perform data communication in a packet switching system by easy credit management. SOLUTION: When a reception buffer has a space for at least one credit, the number of credits on the reception side is reported as '1' to start communication; and when a data packet is received, prescribed credit space information is artificially returned as long as the reception buffer has a space for one or more credits even after data in the data packet is stored in the reception buffer.
