TCP RETRANSMISSION PROCESS METHOD OF A FIXED ADDRESS BASE WHICH IMPROVES OPERATION OF A SYSTEM BY SIMPLIFYING A SCHEDULING ALGORITHM AND A POINTER OPERATION OF A TRANSMISSION BUFFER

摘要

PURPOSE: A TCP(Transmission Control Protocol) retransmission process method of a fixed address base is provided to simplify pointer operation of a transmission buffer and a scheduling algorithm by assigning a fixed address about the transmission buffer.;CONSTITUTION: A transmission buffer Initialization part establishes a transmission buffer of n piece of ethernet frame size for TCP transmission(S10). A transmission buffer data processing part commands a scanning of a transmission buffer to a transmission buffer scan part according to an input of TCP data(S20). The transmission buffer scan part searches the transmission buffer(S30). A transmission buffer data storage part stores the TCP data(S40). A transmission buffer locking control part locks a write protect flag of an 'i'th transmission buffer(S50). A data transmission part transmits a TCP packet corresponding to read data to a receiving side(S60). A reception confirmation processor decides whether received a receipt notification signal of 'k'th data or not(S70). The reception confirmation processor decides time-out for retransmission(S80). The transmission buffer locking control part unlocks the write protect flag of the 'i'th transmission buffer(S90).;COPYRIGHT KIPO 2011
