Document Type and Number:
WIPO Patent Application WO/2001/076193
Kind Code:
A1
Abstract:
A data communication system is provided in which a host computer is connected with a plurality of peripheral storage devices, which may carry out data transmission simultaneously without substantial increases in data transmission time. A data-transmitting node comprises a plurality of data compression means of different compression ratios, measuring means for measuring the effective data transmission rate of a data transmitting node on a communication path, selection means for selecting one of the data compression means according to the effective data transmission rate obtained by the measuring means, and means for adding a data compression type to transmitted data. A data-receiving node comprises means for decompressing received data by recognizing the compression type of the received data based on the information in the data.
