DEVICE AND METHOD FOR MANAGING COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To perform communication by a plurality of data lengths by selecting the data length for each transmission opposite party. SOLUTION: A multi-data length managing part 811 sets or changes the communication data length and the driver transmission interface of a route information table 812 and an information table 813 and the communication data length and the driver reception interface of a multi-data length management table 814. An IP 805 divides transmission data into prescribed communication data length based on the destination address of transmission data by referring to the table 812. Transmission data are transmitted to a network by the communication data length which is stored in a link information table 813 through the use of a selected drier 806 or a virtual driver 810. A multi-data length receiving part 808 selects the driver reception interface based on a transmission source address by referring to the table 814 and receives reception data from the network.
