  • Patent number: 11263172
    Abstract: A method, computer program product, and/or computer system improves a future efficiency of a specific system. One or more processors receive multiple historical data snapshots that describe past operational states of a specific system. The processor(s) identify a time series pattern for the time series of data in the multiple historical snapshots and calculate their variability. The processor(s) then determine that the variability in a first sub-set of the time series pattern is larger than a predefined value, and determine that future values of the first set of the time series pattern are a set of non-forecastable future values. The processor(s) also determine that the variability in a second sub-set of the time series pattern for the data is smaller than the predefined value, and utilizes this second sub-set to modify the specific system at a current time.

  • Patent number: 11258709
    Abstract: In one embodiment, the system identifies one or more geographic areas covered by a communication network. The system determines, for each identified geographic area, a congestion metric for the identified geographic area based at least on a difference between a first and second reference point on a network speed curve, wherein the network speed curve represents download speeds for a volume of traffic in the identified geographic area. The system identifies one or more network traffic congestions in one or more of the identified geographic areas based on a comparison of the respective congestion metrics of the identified geographic areas to a threshold congestion metric. The system sends, to one or more operators of the communication network, one or more alerts about the identified network traffic congestions.

  • Patent number: 11252626
    Abstract: A method for reducing delay during a link switchover is disclosed. The method comprises determining whether transmission of data in progress is a segmented data transmission, and detecting whether there is a link switchover. If there is a link switchover, the method generates new link characteristic header information for a data packet, and determines a segmentation of the data packet based on the new link characteristic header information. The method then generates segmentation header information for the data packet, and transmits the data packet over a current link.

  • Patent number: 11245637
    Abstract: A non-transitory processor-readable medium storing code representing instructions to be executed by a processor can cause the processor to receive an indication to load balance a group of sessions associated with a network node and a switch across a group of links between a gateway device and the switch at a first time. The code causes the processor to calculate at a second time, a load based on the group of sessions and associated with a first set of links in an active configuration before the first time. The code causes the processor to send a signal to cause a set of sessions from the group of sessions to re-establish themselves at a third time based on a threshold value calculated based on the load such that the set of sessions are load balanced across a second set of links in the active configuration at the third time.

  • Patent number: 11240843
    Abstract: The disclosed subject matter is directed towards a clear channel assessment procedure based on a common preamble, such as for use with 3GPP and IEEE 802.11 technologies, or any other radio technology, including for use in the 6 GHz band. Detection of the common preamble is based on detecting known sequences in signal part, which can be detected without decoding the preamble's payload (channel) part to determine an ongoing transmission's duration. If an ongoing transmission is detected, subsequent energy detection monitoring is performed to determine when transmission ends, which can use a different energy detection threshold from what is used in the initial clear channel assessment's energy detection. The technology facilitates the usage of different sampling rates by different radio technologies that work concurrently in the same unlicensed band, by correlating a received preamble with a stored preamble that accounts for deterministic distortions arising from the different sampling rates.

  • Patent number: 11240637
    Abstract: A wireless communication system has an access point managing a first wireless local area network. To transmit the frame, the access point: obtains data to be transmitted in multicast mode; obtains data to be transmitted in unicast mode; and constructs a physical-layer header including: in a common signalling field, an identification of each channel resource intended to be used for making the frame transmission, whether this be for the data to be transmitted in unicast mode or in multicast mode; and, in each field in a series of specific signalling fields, information representing an association between a channel resource identifier used and a unique identifier of the destination concerned or group of destinations concerned. Thus each destination can determine each channel resource to listen to in order to receive the data that are addressed to it, whether this be in unicast mode or in multicast mode.
