20080250186 | BUS CONNECTING DEVICE FOR CONNECTING HOST WITH EXTERNAL DEVICE - A detecting unit detects a connection of an external device to a connection port and stores the connection in a bridge state storage unit. This setting is autonomously completed by a device before an initial configuration is started by a host. A data transfer unit receives initial configuration data of a link-connection bridge from the host. Data is transferred to the linked-uplink-connection bridge with reference to the bridge state storage unit, data to a bridge which is not linked up is wasted, or an Unsupported Request is returned to the host to represent the absence of the link-connection bridge. | 10-09-2008 |
20090059928 | COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, ABSENT PACKET DETECTING METHOD AND ABSENT PACKET DETECTING PROGRAM - Any packet loss is detected very quickly by means of only a series of sequence number in a multi-path environment where a transmitter and a receiver are connected to each other by way of a plurality of networks when no inversion of sequence arises in any of the networks.
