Apple has been granted a patent (number 7317694) by the U.S. Patent & Trademark Office for a method and apparatus for border node behavior on a full-duplex bus. It relates to bus management. In particular, the present invention relates to the behavior of border nodes within a high performance serial bus system.
According to Apple, a method is disclosed for determining and communicating the existence of a hybrid bus. The method comprises the acts of determining whether the node has a connection to a Legacy link layer; if the node determines that it has a connection to a Legacy link layer, then transmitting a Self-ID packet without a Speed Code; and if the node determines that it does not have a connection to a Legacy link layer, then transmitting a Self-ID packet without a Speed Code.
The inventors are Jerrold V. Hauck and Colin Whitby-Strevens.
