  • Patent number: 10917353
    Abstract: In various embodiments, methods and systems for implementing network traffic flow logging in a distributed computing system are provided. At a high level, the network traffic flow logger is implemented using a network traffic flow logger framework that includes a plurality of modular network traffic flow logging objects for adjustable processing of network flow events. In operation, a plurality of tokens is counted at a first throttling rate. The first throttling rate is associated with a maximum number of tokens threshold. The maximum number of tokens threshold is an adjustable threshold. A flow event is accessed, where flow events are quantified based on tokens. The flow event is queued, based on a count of the plurality of tokens or the maximum number of tokens threshold. Based on queueing the flow event, the first throttling rate is adjusted to a second throttling rate based on a queue length of the queue.

  • Patent number: 10652769
    Abstract: A method for wireless network operation includes, in a cluster of transmitters and receivers in a wireless network, configuring a transmitter of a first node and a transmitter of an interfering node to transmit only in their own dedicated time-frequency partition a signal at a non-zero transmission power, and to transmit a zero power signal in a second time-frequency partition. A receiver of a second node is configured to measure a first received power in a third time-frequency partition dedicated to an interfering transmitter and a second received power in the second time-frequency partition dedicated to receive interference from outside the cluster. A net signal power is determined by subtracting the second received power from the first received power. A coupling loss between the interfering transmitter and the receiver is computed based on the net signal power and the non-zero transmission power.
