  • Patent number: 11337087
    Abstract: A method, system and computer-readable medium where a weighted composite quality index having a plurality of components for a network element is identified. A historical baseline value from historical data for each component is determined, and a deviation from the historical baseline values is measured. A risk level for the deviation is assigned. A loss score for the measured components is computed by mapping the risk level to a numerical score. An aggregated risk score based on a sum of weighted risk scores for each of the components is computed. An expected risk score based on probabilities associated with the aggregated risk score is determined by computing future probabilities of each risk level at the network element based on a trained machine learning model.

  • Patent number: 11303472
    Abstract: A new processing architecture is described in which a data processing unit (DPU) is utilized within a device. Unlike conventional compute models that are centered around a central processing unit (CPU), example implementations described herein leverage a DPU that is specially designed and optimized for a data-centric computing model in which the data processing tasks are centered around, and the primary responsibility of, the DPU. For example, various data processing tasks, such as networking, security, and storage, as well as related work acceleration, distribution and scheduling, and other such tasks are the domain of the DPU. The DPU may be viewed as a highly programmable, high-performance input/output (I/O) and data-processing hub designed to aggregate and process network and storage I/O to and from multiple other components and/or devices. This frees resources of the CPU, if present, for computing-intensive tasks.

  • Patent number: 11303531
    Abstract: Systems, methods, and computer-readable media for generating counterexamples for equivalence failures between models of network intents. A listing of conflict rules corresponding to an equivalence failure between at least first and seconds model of networks intents describing the operation and communication of network devices in a network is obtained. A logical exclusive disjunction between first conflict rules from the first model and corresponding second conflict rules from the second model is calculated. One or more counterexamples corresponding to the equivalence failure are generated based at least in part on the logical exclusive disjunction, such that a given counterexample comprises network and packet conditions that cause the first conflict rules to trigger a first action and cause the second conflict rules to trigger a second action that is different from the first action. Hot fields that are more likely to be associated with the equivalence failure are identified in the counterexample.

  • Patent number: 11202297
    Abstract: Systems and methods described herein provide a centralized solution for interference mitigation that focuses on efficient spectrum management. Wireless Access Points (APs) collect interference measurements for wireless channels and generate corresponding interferer airtime estimates. The APs also determine Packet Error Rates (PERs) for wireless client devices currently being served via the channels by the APs. The APs send the interferer airtime measurements and the PERs to a centralized controller. If an interferer airtime estimate and a PER for a particular channel satisfy predefined threshold conditions, the controller modifies an allocation of wireless bandwidth for an AP that is currently using the channel and sends a message to the AP indicating how the allocation has been modified.

  • Patent number: 11076314
    Abstract: A mobility management entity (MME) can enable overload control of data transmission via control plane in an evolved packet system (EPS), optimized for cellular internet of things (CIoT), by use of a control plane data backoff timer that suppresses the use of control plane for data transfer by a user equipment (UE) for the duration of the timer. For example, an MME sends a control plane data backoff timer to a UE that suppresses the use of control plane for data transfer for the duration of the timer. Alternatively, when an MME load reaches a threshold, an MME triggers an Overload Start message and sends it to the RAN node, so that the RAN node can restrict selecting this MME for UEs requiring data transfer using control plane CIoT optimization. The RAN node can reject these UEs and return a wait timer in an RRC Connection Release message.

  • Patent number: 11055313
    Abstract: The “free world replication protocol” makes use of client computing resources, wherein the clients are not part of the replicated key-value store, but instead reside in the “free world” outside of the dedicated resources of the nodes of the replicated key-value store. In the free world replication protocol, only a single “write” client is authorized to modify the key-value store at any time but any number of clients may be authorized to read data from the key-value store. The write client sends its transactions to multiple nodes in the replicated key-value store. As a result, the latency between the transaction being sent from the client and the transaction being received by the multiple nodes is reduced by comparison to existing protocols in which each client sends transactions to a single node and that node forwards the transactions. A consensus protocol, driven by a master node, is used to periodically ensure consistency, but the data transactions themselves do not make use of a master node.

  • Patent number: 10530677
    Abstract: A network element employing multiple namespaces in performing IP packet routing. The network element maintaining two or more namespaces. A first namespace corresponds to an in-band network domain and a second namespace corresponds to an out-of-band network domain. The network element performing IP packet routing over the in-band network domain and the out-of-band network domain using said two or more namespaces. Embodiments allow operators to more easily implement separate routing tables for “in-band” and “out-of-band” communication. Having separate routing tables for in-band and out-of-band communication prevents malicious CPEs and hacked CMs from directly communicating to servers on the out-of-band network, thereby increasing security for CMTS operators.

  • Patent number: 10462015
    Abstract: The embodiments herein uses sensor APs (e.g., APs that do not associate with client devices) to detect changes in physical topology that affect cell coverage areas and determine cell edges for different client devices. In one embodiment, using test signals (e.g., test probes) transmitted by the sensor APs which are received at normal APs which do associate with client devices, a controller can generate baselines which characterize the signals received from the sensor APs at the normal APs. At intervals or in response to an unexpected action by a client device, one or more of the sensor APs can transmit another test signal. Because the test signal can be received at multiple normal APs, the controller can compare the test signal to the baselines to identify whether there has been a change in physical topology that affects the cell coverage area for the client device.

  • Patent number: 10452547
    Abstract: A cache coherence system manages both internode and intranode cache coherence in a cluster of nodes. Each node in the cluster of nodes is either a collection of processors running an intranode coherence protocol between themselves, or a single processor. A node comprises a plurality of coherence ordering units (COUs) that are hardware circuits configured to manage intranode coherence of caches within the node and/or internode coherence with caches on other nodes in the cluster. Each node contains one or more directories which tracks the state of cache line entries managed by the particular node. Each node may also contain one or more scoreboards for managing the status of ongoing transactions. The internode cache coherence protocol implemented in the COUs may be used to detect and resolve communications errors, such as dropped message packets between nodes, late message delivery at a node, or node failure.
