Abstract: In one embodiment, a non-powered, non-ethernet device can be plugged into an ethernet port of a host to transfer data stored on the device to the host.

Abstract: In a circuit delivering common mode inline power over a pair of conductors imbalance in the current carried by the first and second conductors of the pair of conductors is detected and compensated with a bias current applied to counter the imbalance.

Abstract: In a wired data telecommunication network power sourcing equipment (PSE) coupled to a powered device (PD) carries out an inline power discovery process to verify that the PD is adapted to receive inline power, then a plurality of classification cycles are carried out to convey a series of inline power classes back to the PSE. The series of inline power classes may all be the same, in which case the PD is legacy equipment and is adapted to receive the power level corresponding to that class. If they are not all the same, information is thus conveyed to the PSE which may, for example, correspond to a specific power level to be applied or to other information.

Abstract: The present invention communication network system and method facilitates authentication and registration in a communication network as mobile nodes move from one geographical region to another. Multiple wireless domain services (WDSs) share client authentication information permitting relatively seamless roaming between subnets with minimal interruptions and delays. In one embodiment, a wireless domain service network communication method is performed utilizing partial authentication processes. A mobile node engages in an authentication protocol with a first wireless domain service (WDS) access point in a first subnet. The authentication credentials are forwarded to a second wireless domain service in a second subnet if the authentication protocol is successfully completed. The forwarded authentication credentials are utilized to authenticate the client entering the service area of the second wireless domain service in the second subnet.
