"METHOD AND EQUIPMENT FOR MAPPING PRIORIZED QOS PACKAGES FOR PARAMETRIED QOS AND VICE VERSA CHANNELS". An apparatus and method for adapting QOS data packets, such as those used by IEEE 802.1q priority Ethernet devices for parameterized data packets that can be transmitted over the isochronous channel of an IEEE 1394, Hyper LAN 2 network, or described herein is described. similar network or serial bus with isochronous services. An adapter device uses the presence of a priority on a priority-based QOS LAN as an indication to establish an isochronous channel on the IEEE 1394, hyper LAN 2 device, or similar device for the transfer of a potential current. When the adapter device detects the priority field and has determined that, to reach the destination device, the next segment is through an isochronous LAN (for example, IEEE 1394 or Hyper LAN 2), the adapter establishes an isochronous channel. (if it is the first packet in a stream) to the next device in the current path and then forwards such packet and any future packets that are identically tagged (addresses and priorities) through such an isochronous channel. The adapter is also configured to convert packets that have been sent through the isochron channel in the manner described above back to prioritized data packets for transmission to an Ethernet device or other prioritized QOS device. Another feature of the adapter and method is the dynamic adjustment.
