Abstract: Techniques for implementing a last known good (LKG) client-side cache for DNS resiliency are disclosed. A first DNS request is submitted to a DNS server. A first DNS resolution that resolves an IP address for a domain name is received. A service stores the first DNS resolution in an LKG cache residing on the local host. A second DNS request is sent, where the second DNS request again requests to resolve the same domain name. In response to determining that a second DNS resolution for the second DNS request has not been received, the service obtains the IP address for the domain name from the LKG cache.

Abstract: A system detects a fuel dispensing operation that indicates fuel is being dispensed from the fuel dispensing terminal. The system determines an identifier value associated with a volume of fuel dispensed from the fuel dispensing terminal. The system determines a measured volume per unit time parameter associated with the fuel dispensed from the fuel dispensing terminal by dividing the determined identifier value by a unit parameter. The system compares the measured volume per unit time parameter with a threshold volume per unit time parameter. In response to determining that the measured volume per unit time parameter is less than the threshold volume per unit time parameter, the system instructs the fuel dispensing terminal to stop dispensing fuel.

Abstract: A system determines an interaction period during which a fuel dispensing operation is performed at a fuel dispensing terminal. The system determines a measured volume per unit time parameter associated with fuel dispensed from the fuel dispensing terminal by dividing the determined volume for fuel by the interaction period. The system compares the measured volume per unit time parameter with a threshold volume per unit time parameter. In response to determining that the measured volume per unit time parameter is less than the threshold volume per unit time parameter, the system retrieves a video feed that shows the fuel dispensing terminal during the fuel dispensing operation. The system creates a file for the fuel dispensing operation. The system stores the video feed in the created file.

Abstract: Methods and systems for detecting a preamble of a data packet in wireless communication systems is provided. To determine a preamble from a received signal, which may include a noise-altered preamble bit sequence, linear feedback shift registers (LFSRs) can be used to generate a count of the received preamble, and the count is compared to pre-generated scores to identify a match. Example methods include for each of a number of different preamble orientations of a preamble, generating a count value based on a comparison of bits of the preamble with a random bit sequence to produce a sequence of count values, and comparing the sequence of count values with m sequences of count values. A sequence of count values is identified that includes a maximum number of matching elements, and the received preamble is determined to be one of the m preambles corresponding to the identified sequence.

Abstract: Sub-channels in cells of an Orthogonal Frequency Division Multiple Access (OFDMA) network are formed based on random permutations of a set of subcarrier indices. The random permutations are performed for each cell of the network using a pseudo-random number generator (PRNG) and a shuffle technique. Different initial states of the PRNG are used to generate the random permutation of the subcarrier indices for each cell. In an embodiment, sub-carriers represented by a contiguous group of indices in the random permutation obtained for a cell are assigned to form a sub-channel. Interference diversity for the OFDMA network is thereby improved.

Abstract: A network system employs path health information to select an acceptable path between a source node and destination node within an information handling system (IHS) and/or between a source node within one IHS and a destination node within another IHS. One or more switches may connect these two IHSs together. The network system accesses the path health information to determine the availability of paths for communicating between nodes.
