Data transfer method and data transfer apparatus for hybrid isochronous/ asynchronous networks

摘要

According to a data transfer apparatus of the present invention, a wait time setting section (14a) sets a wait time. The wait time is selected so as to be equal to or greater than a transmission delay time, as detected by a delay time detection section (12a), that is incurred between data transfer apparatuses (1a) and (1b), and to guarantee a bandwidth, as detected by a bandwidth detection section (18a), that is required for data signals which require periodic transmission. As a result, it becomes possible to perform a long-distance transmission of data signals which require periodic transmission and sporadically-occurring asynchronous data signal by applying time-multiplex thereto.
