Abstract: Apparatuses, methods and storage medium associated with techniques to detect soft errors of a TCAM are disclosed herein. In embodiments, an apparatus may include a TCAM, and logic and/or circuitry to apply a plurality of fault detection patterns to the TCAM to generate respective hit output arrays for the plurality of fault detection patterns, generate parity signatures for the hit output arrays, and compare the generated parity signatures to expected parity values. Other embodiments may be disclosed or claimed.

Abstract: A plurality of physical queues, in a memory of a network device, are logically coupled to define a logical queue. Packets are received by the network device, and respective data units associated with the packets are distributed to the plurality of physical queues for storage according to a predetermined scheme i) to alternate among the plurality of physical queues, and ii) to maintain an order of data units stored in the logical queue. The data units are retrieved from the plurality of physical queues according to the predetermined scheme i) to alternate among the plurality of physical queues, and ii) to maintain the order of the data units.

Abstract: In a method for queuing data units in a network device, a plurality of physical queues corresponding to a port of the network device are defined in a memory of the network device. Respective subsets of the plurality of physical queues are logically coupled to define a plurality of logical queues that are respectively formed of logically coupled physical queues. The logical queues correspond to respective data flows of the port. A data unit belonging to a data flow is received. A logical queue for storing the data unit is selected, based on the data flow of the data unit, from the plurality of logical queues The A physical queue for storing the data unit is then selected from the subset of physical queues that corresponds to the selected logical queue. The data unit is stored in the selected physical queue.
