Processing of MLD control packets in an access point (AP) connected to a digital network. According to the present invention, an AP in a network converts MLD queries from multicast to unicast and sends these unicast packets to each client of the AP. These MLD query packets may be filtered or restricted by per-user client rules These MLD query packets may also be tagged as high priority packets to speed their delivery. The AP also suppresses the retransmission of MLD Join packets to clients of the AP.

The invention provides a wireless transmission apparatus, a phase compensating apparatus, and a phase compensating method thereof. The phase compensating apparatus includes main transmission wire, a plurality of capacitors, and at least one phase compensating unit. The main transmission wire is coupled between the output end of the power amplifier and the input end of the impedance matching apparatus. A first end of each of the capacitors is coupled to the main transmission wire. The phase compensating unit has two ends for being coupled to second ends of two of the capacitors.

Methods and arrangements for assessing impact of an event on a network. An event notification is received relative to traffic in the network. Metadata are extracted from the notification, and the extracted metadata are converted into a predetermined format for processing. The converted metadata are received, and an impact of the event on traffic in the network is determined. Other variants and embodiments are broadly contemplated herein.

Systems and methods for cabling verification may include one or more operations including, but not limited to: receiving floor plan data representing a floor plan of a premises; receiving at least one user input specifying a location of at least one cabling endpoint relative to the floor plan; receiving at least one user input selecting at least one cabling verification test for the at least one cabling endpoint; receiving one or more cabling verification test results for the at least one cabling endpoint obtained by at least one testing device; and updating at least one database element associated with the at least one cabling endpoint and maintained by the cloud-based server.

An inter-circuit board connector connects a first circuit board to a second circuit board. The inter-circuit board connector includes power pins to transmit power from the first circuit board to the second circuit board. Each power pin provides an equal amount of current from the first circuit board to the second circuit board. The inter-circuit board connector includes a current sensor to measure current on a selected number of the power pins that can be less than a total number of the power pins.

In a reset period of a first stage, a switching circuit is turned on, and high-level driving voltages are output from driving circuits. In a charge transfer period subsequent to the reset period, the switching circuit is turned off, and low-level driving voltages are output from the driving circuits. It is determined whether or not an output voltage of an amplifier circuit in the charge transfer period is included in a normal range. In the inspection of a second stage subsequent to the first stage, in the same manner as in the normal measurement, voltages having opposite phases are output from the driving circuits in the reset period and the charge transfer period, and it is determined whether or not the output voltage of the amplifier circuit in the charge transfer period is included in a normal range.
