    Abstract: In one embodiment, a method includes sampling text in a received packet at a network device and analyzing the sampled text using a sampled deterministic finite automata (DFA) to identify matches between a set of regular expressions and the text. The sampled DFA is created with the regular expressions sampled at a sampling rate calculated for the regular expressions using operations including selecting a minimum sampling rate from sampling rates computed for each of the regular expressions based on a minimum length of the text that can match the regular expression. An apparatus and logic are also disclosed herein.

    Abstract: Embodiments provide techniques for transmitting data packets across a deterministic Ethernet network. Embodiments receive, at a first device in the deterministic Ethernet network, a deterministic binary schedule specifying timing information for transmitting data fragments relating to a plurality of data flows. Data packets to transmit to a destination device within the deterministic Ethernet network are received at the first device. Embodiments include fragmenting each of the data packets into two or more fragments and encoding at least one of the two or more fragments for each of the data packets with a respective sparse graph code. The encoded fragments are transmitted to the destination device, across multiple paths through the deterministic Ethernet network, according to timing information specified in the deterministic binary schedule.

    Abstract: In one embodiment, an illustrative method herein may comprise: obtaining, by a process, operational performance metrics associated with one or more devices performing an operation and contemporaneous situational sensor data associated with the one or more devices performing the operation; establishing, by the process, a correlation between a health of the operational performance metrics and the contemporaneous situational sensor data for the one or more devices while performing the operation; determining, by the process, an adjustment to increase the health of the operational performance metrics for a particular device of the one or more devices based on the correlation; and communicating, by the process, the adjustment to a receiving device to facilitate adjusting of the particular device.

    Abstract: In one embodiment, a method in a multi-tenant wireless network comprises determining a first user private network (UPN) for a first device of a first user. The first UPN provides discovery, by the first device, of other devices on the wireless network to a first subset of other devices on the wireless network. The method further comprises determining a second UPN for the first device of the first user. The second UPN provides discovery, by the first device, of other devices on the wireless network to a second subset of other devices on the wireless network. The method further comprises providing discovery of the first subset and second subset of other devices on the wireless network to the first device of the first user. Discovery of the second subset is provided dynamically based on a current location of the first device.
