Method of and apparatus for providing reserved bandwidth to ethernet devices over switched ethernet including a home network wall plate having a combined IEEE 1394 and ethernet modified HUB
A combined IEEE 1394-2000 and ethernet network allows devices to operate according to both the IEEE 1394-2000 protocol and the ethernet protocol. The devices within the network are able to send IEEE 1394-2000 isochronous data, IEEE 1394-2000 asynchronous data and ethernet data. Both IEEE 1394-2000 and ethernet devices are coupled to modified hubs (MHUBS) to form a local cluster. The MHUBS are coupled to an ethernet switch which controls communications between devices in different local clusters. The ethernet switch and the MHUBS obey an isochronous interval in which all isochronous data transfers and asynchronous data transfers from ethernet devices with an allocation of reserved bandwidth will be allowed. The ethernet switch sends a periodic isotick signal to begin the isochronous interval. Bandwidth remaining after the isochronous interval is then allocated to the IEEE 1394-2000 asynchronous traffic, until the start of the next isochronous interval.
