ABSTRACT:
A system and method for effectively performing isochronous data transfers comprises a network device including an input/output (I/O) bus that is coupled to an input/output (I/O) node and an isochronous-capable network interface. The network interface and the I/O node may send requests to an arbiter for control of the I/O bus to perform a data transfer operation. In accordance with the present invention, an arbiter filter is interposed between the arbiter and both the network interface and the I/O node to filter respective requests for control of the I/O bus. The network interface advantageously provides an isochronous request to the arbiter filter to thereby de-assert conflicting requests so that the network interface may effectively perform a time-sensitive isochronous data transfer.
