Translation bridge between ethernet and 1394A local links for consumer electronics devices
First Claim
1. A method of providing address translation between a first network and an external network, the first network including logical devices on a local link and the external network including logical devices on another local link, the method comprising the steps of:
- in a translation device;
allocating a link local address for each of the external logical devices in the external network, representing to the devices in the first network, each of the external logical devices at the corresponding allocated link local addresses, wherein the translation device presents to the devices in the first network a union of the external logical devices.

Abstract
A translation bridge is provided between Ethernet and 1394A local links for consumer electronics devices. On each logical local link, a link local IP address is allocated for each other logical link to be bridged. The translation bridge then represents each external logical unit as that singular IP address concatenated with an assigned unique Port number which corresponds to the actual IP address and Port number of the external logical unit on its attached link. Therefore, all of the devices on an external link appear as logical units in one physical device. That physical device then presents the union of all of the external logical units'"'"' 2027 file response as the local link 2027 file response for discovery. Then, physical packets are translated to the external devices as if emanating from the link local corresponding device. Further, addresses in hyperlinks are translated in exactly the same way, treating addresses and port numbers as the addresses.

16. A controller that provides address translation between a first network and an external network, the first network including logical devices on a local link and the external network including logical devices on another local link, the controller comprising:
a translation device that allocates a link local address for each of the external logical devices in the external network, and represents to the devices in the first network, each of the external logical devices at the corresponding allocated link local addresses, wherein the translation device presents to the devices in the first network a union of the external logical devices. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
