INFORMATION TRANSFER CONFIRMATION SYSTEM FOR COMPUTER NETWORK

摘要

PURPOSE:To simplify the control for the units at the reception side and thus to ensure a high efficiency for the packet transfer by providing the answer request on the packet to be transmitted next in case the answer of the reception confirmation information is required from the reception side before reaching the fixed packet number of the reception side at the transmission side. CONSTITUTION:Packet transmission process mechanism 1 analyzes the information through analysis mechanism 2 and then carries out transmission 3 and packet holding 5 under the control of transmission procedure control mechanism 4; while packet reception process mechanism 6 performs transfer confirmation answer 8 and message assembling 9 under the control of transmission procedure control mechanism 7. In other words, the answer request given from the transmission side is detected at the reception side and then detects the prescribed packet number to answer the reception confirming information to the trnamission side. At the transmission side, the answer request is set up on the packet to be transmitted next in case the answer of the recetion confirming information sent from the reception side is required before reaching the prescribed packet number of the reception side. Thus, the reception confirming information is obtained quickly from the reception side. As a result, the control is simplified for the units of the reception side, thus ensuring a high efficiency for the packed transfer.
