EVALUATION OF ACKNOWLEDGMENT METHODS FOR HIGH-SPEED DATA-TRANSMISSION

The protocol in the open system interconnection (OSI) basic reference model is specified as a system with a multilayer structure, The perfor mance of the network is related closely to the network configuration a nd the protocol parameters. The authors have been attempting to evalua te the transmission efficiency of the network using the multilayered p rotocol, with the transmission speed, the window size, and the transmi ssion delay as the parameters. It is assumed in the studies that the a cknowledgement is returned at the end of each window. On the other han d, it is seen that the throughput of the network in the high-speed tra nsmission is affected greatly by the acknowledgement method. This pape r notes this point and evaluates the relation between the acknowledgem ent method and the transmission efficiency. To achieve the desired tra nsmission speed, the conditions for the window size, the acknowledgeme nt method, and the protocol processing time are presented.
