Abstract: Various embodiment provide a multi-terminal cooperative working method, a terminal device, and a multi-terminal cooperative system. In those embodiments, a primary device can send networking information to a plurality of secondary devices, and the primary device has a permission to manage the cooperative network. The primary device can receive networking confirmation information sent by the plurality of secondary devices; and send configuration information to the plurality of secondary devices separately. The configuration information can be used to instruct to switch, based on a preset management permission switching mechanism when the primary device becomes abnormal or the primary device exits from the cooperative network, the permission to manage the cooperative network. The primary device can clear the secondary device from the cooperative network the secondary device becomes abnormal. In this way, robustness of the cooperative network can be improved.

Abstract: A power over Ethernet (PoE) power supplying method where power sourcing equipment (PSE) and a powered device exchange link layer discovery protocol data units (LLDPDUs). Each of the LLDPDUs includes two power values. Each of the power values indicates requested or allocated power for one of two sets of cable pairs of the Ethernet twisted pair connecting the PSE and the powered device. Accordingly, the supplied powers to the powered device at sets of cable pairs are independent from each other.

Abstract: A power over Ethernet method where power sourcing equipment (PSE) detects and determines that a first set of cable pairs and a second set of cable pairs of an Ethernet twisted pair are connected to a valid powered device (PD), the PSE receives a link layer discovery protocol data unit (LLDPDU) from the PD, where the LLDPDU includes a load quantity type-length-value (TLV) used to notify a quantity of PD loads included in the PD, and when the PD receives power from both the first set of cable pairs and the second set of cable pairs, and the PD includes two PD interfaces, and the PD includes two PD loads, the PSE supplies power to the PD at a first power using the first set of cable pairs, and supplies power to the PD at a second power using the second set of cable pairs.
