Abstract: In an implementation, a method is provided. The method may include: receiving a sensor application by a network platform, the network platform comprising a processing module and a plurality of ports, and wherein a first portion of the processing module is allocated to an operating system of the network platform; allocating a second portion of the processing module to the sensor application by the network platform; executing the sensor application by the second portion of the processing module; emulating a port of the plurality of ports by the second portion of the processing module; and allowing the executed sensor application to interact with the operating system through the emulated port.

Abstract: A method for verifying interconnection of a PSE and PD with 4-pair PoE capabilities includes performing a first classification event on first and second pairs, respectively, and detecting a first predetermined class current on first and second sets of twisted pairs, respectively. The method includes performing a second classification event on first and second pairs, respectively, and detecting first and second predetermined class currents on first and second pairs, respectively. After expiration of a first variable delay period related to a first pseudo-random variable of the PSE, the method includes performing a third classification event on the first pair and detecting a first derived class current on the first pair. After expiration of a second variable delay period related to a second pseudo-random variable of the PD, the method includes performing the third classification event on the second pair and detecting a second derived class current on the second pair.

Abstract: A technique is able to direct a power signal from a port power controller to one of multiple physical ports. The technique involves activating a set of port power controllers. Each port power controller is constructed and arranged to deliver power to a device through at most one physical port at a time. The technique further involves performing a set of discovery operations to discover device presence, the set of discovery operations providing discovery data. The technique further involves providing, based on the discovery data provided by the set of discovery operations, a set of switching signals to switching circuitry which is coupled to a set of physical ports. The switching circuitry is constructed and arranged to steer power signals from the activated set of port power controllers through the set of physical ports to deliver power to a set of devices.
