Abstract: Embodiments described herein can enable minimum processing performed at a signal device level, such that the majority of the non-domain-specific processing can be offloaded to a processing device. For example, the processing device can receive signal data from a signal device, preprocess the signal data to obtain preprocessed signal data having a data format for domain-specific processing by software executed by at least one processing unit of a processing platform, and provide the preprocessed signal data for domain-specific processing by the software executed by the at least one processing unit.

Abstract: A routing controller (30) includes an interface (68) and multiple processors (60) The interface is configured to receive a permutation (76) defining requested interconnections between N input ports and N output ports of a Benes network (24). The Benes network includes multiple 2-by-2 switches (42), and is reducible in a plurality of nested subnetworks associated with respective nesting levels, down to irreducible subnetworks including a single 2-by-2 switch. The multiple processors are configured to collectively determine a setting of the 2-by-2 switches that implements the received permutation, including determining sub-settings for two or more subnetworks of a given nesting level in parallel, and to configure the multiple 2-by-2 switches of the Benes network in accordance with the determined setting.

Abstract: Systems, methods, apparatuses, and computer program products for reducing data port downtime are provided. An example network interface device of the present disclosure includes a first data port and a second data port. The network interface device performs a first link training process associated with the first data port coupled to a first communication link to determine a first communication parameter set for the first communication link. The network interface device then deactivates the first data port and performs a second link training process associated the second data port coupled to a second communication link to determine a second communication parameter set. Based on a network usage parameter set associated with a data plane of the network interface device, the network interface device determines whether to activate the first data port concurrently with the second data port.

Abstract: Systems, devices, and methods are described herein for reducing a link bringup time period for optical switching between network devices. An example method of the present disclosure receives an indication of a reconfiguration condition associated with an optical switch communicatively coupled to an optical communication channel and based on the reconfiguration condition, selects first data associated with a storage device or second data associated with a pattern generator device for transmission to a first network device. Selecting the first or second data may be based on a digital logic signal that indicates whether data is actively received from the second network device via the optical communication channel or may be based on a defined schedule for reconfiguring the optical switch.
