DATA TRANSFER APPARATUS, PRIORITY CONTROL METHOD, AND PRIORITY CONTROL PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a data transfer apparatus in the simplified structure for enabling control with excellent line usage efficiency while ensuring frequency band in the priority port. PSOLUTION: The data transfer apparatus has an over-subscribe function for assigning a frequency band exceeding the back plane band to a group of the ports. The data transfer apparatus is constituted, including a buffer for storing data inputted from each port, an input path setting means for setting a path between each port and the buffer, and an output path setting means for setting the path between the buffer and an output channel, in order to dynamically generate a link by switching the paths in accordance with priority of each port to control the frequency band to be used.
