Abstract: A method for identifying a failed network interface card in a system having two NICs configured as a team includes the steps of transmitting a first data packet from the first NIC to a third NIC, wherein the third NIC is not a member of the team, and transmitting a second data packet from the first NIC to the second NIC or from the second NIC to the third NIC, depending on whether the third NIC responds to the transmission of the first data packet. One advantage of the disclosed method is that it specifically identifies which NIC within the team has failed, which is something that cannot be determined by simply exchanging packets between the two NICs.

Abstract: A communications link of multiple parallel communications lines includes at least one redundant line. In a first aspect, the lines are periodically recalibrated one at a time while the others carry functional data. If a fault is detected, the faulty line is disabled and the remaining previously calibrated lines transmit functional data. In a second aspect, impending line malfunction is detected from anomalies during calibration. In a third aspect, line malfunction is detected from receiver circuit output by determining a logical lane upon which each detected error occurs, and by mapping the logical lane to a physical line currently carrying the logical lane data.

Abstract: A method begins by a processing module detecting a potential dispersed storage network (DSN) protocol issue that effects access of dispersed storage error encoded data within a DSN. The method continues with the processing module identifying a DSN entity based on the DSN protocol issue and generating a DSN protocol inquiry frame. The method continues with the processing module transmitting the DSN protocol inquiry frame to the DSN entity. The method continues with the processing module receiving a DSN protocol response frame from the DSN entity and resolving the DSN protocol issue based on the DSN protocol response frame.

Abstract: Systems and methods of testing a wireless network are provided. Simulated user data, spread across all user data sub-carriers of all sub-channels of a frequency band assigned for transmissions, is transmitted by a number of base stations surrounding a base station under test. The power level of the simulated user data is determined based on a selected network load. A mobile station receives signals from the base station under test and the number of base stations, and the interference caused by the simulated user data to the transmission from the base station under test is determined. When less than 100% loading is employed for testing, the sub-channels carrying the simulated user data can vary on a frame-by-frame basis.
