The solder-joint integrity of digital electronic packages, such as FPGAs or microcontrollers that have internally connected input/output buffers, is evaluated by applying a time-varying voltage through one or more solder-joint networks to charge a charge-storage component. Each network includes an I/O buffer on the die in the package and a solder-joint connection, typically one or more such connections inside the package and between the package and a board. The time constant for charging the component is proportional to the resistance of the solder-joint network, hence the voltage across the charge-storage component is a measurement of the integrity of the solder-joint network.

A system and method detects within an IP network an offending network device that has been adversely affecting the IP network performance. A discovery protocol frame is propagated to successive network switches and is formed as a field having a query for inquiring within each network switch to which the frame is propagated whether the network switch has a database entry regarding the MAC address and switch port for the offending network device to locate the offending network device. This discovery protocol frame includes a command for any network switch that has the offending network device connected thereto to disable the switch port to which the offending network device is connected or block all data traffic from the MAC address of the offending network device.

A personal computer's (PC) microprocessor is used to provide both the physical layer (PHY) and media access control (MAC) processing functions required to implement a wireless local area network (WLAN) adapter. This technique uses the polling mechanism associated with the power save (PS) functionality of WLAN protocol to relieve networking stress on the host processing system. It does this while maintaining networking integrity and packet delivery. The WLAN protocol polling mechanism is used to briefly inhibit the transfer of packets from the WLAN access point (AP) during peak periods of network traffic and/or host processor loading. Because the modulation, demodulation, and MAC functions, typically implemented in dedicated hardware on existing adapters are implemented in software running on the host PC microprocessor, other host system processes and applications can interfere with these time critical functions. Conversely, latency introduced by WLAN specific processing tasks during peak periods of network traffic may cause unacceptable delays to the other processes and applications requiring microprocessor attention. In addition to its primary stated purpose of allowing WLAN mobile stations to save power, this technique will use power save polling as a method for controlling delivery of network packets when the host is heavily loaded or when peak interrupt latencies make reliable packet delivery difficult or impossible.

The method includes registering, by a certifying node, one or more edge devices with a peer to peer network. Upon registration, an incrementally updated ML model is received from a first registered device at the certifying node. The certifying node accepts the incrementally updated ML model if a contribution of the first edge device is within a predetermined threshold, and else rejects the updated ML model if the contribution is beyond the predetermined threshold. Limiting the contribution by each edge device enables prevention of skew by any of the edge devices at the certifying node. Upon accepting the updated ML model, the certifying node certifies the updated ML model and transfers the certified ML model to one or more other edge devices in the peer to peer network.
