Abstract
A communication method applied to a communication system is provided for enhancing communication performance such as a throughput and a turn around time in the so-called intra-computer communication. In the communication procedure, when a source end system (SES) like a host computer transfers data to a destination end system (DES) such as a LAN or a WAN through a communication control system (CCS), the CCS served as a virtual destination receives the data and transmits an acknowledge (+Cresp) to the SES. In response to the acknowledge (+Crest), the SES performs the next transfer of the data. In response to the last acknowledge, the SES operates to output an indication about completion of the data transmission (End TX-C). The CCS continues to transfer the data temporarily received from the SES to the DES unless the CCS receives the acknowledge from the DES. The acknowledge +Cresp contains information about an amount of data transferred from the CCS to the DES. The SES operates to calculate an amount of data to be transferred on the basis of the amount of transferred data contained in the information, a window size and the amount of data so far transferred to the CCS.
