CONTROL METHOD FOR DATA FLOW IN COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a control method for a data flow in a communication system where a deadlock state of transmission/receiving terminals caused by missing a WSN(Window Size Number) sent from the receiving end to the transmission end is prevented and eliminated. SOLUTION: The control method is characterized in that it includes a step where the receiving terminal transmits number of desired window sizes of 0 or over to the transmission terminal, a step where the step above is repeated until the transmission terminal transmits a protocol data unit to the receiving terminal after a predetermined time of a timer expires through the final transmission of the window size number, and a step where the connection between the transmission and the receiving terminals is finished when the protocol data unit to be sent to the receiving terminal does not exist until the step above is repeated by the number of times that is already decided.
