  • Patent number: 11353855
    Abstract: An OT-IT (operational technology-information technology) service of a provider network allows operators to configure gateway connectors for data sources (e.g., machines at an industrial site) and allows developers to specify workflows that consume data from the data sources. To do so, the OT-IT service provides an operator interface to receive topology data for the client's remote network. The OT-IT service configures connectors for data sources based on the topology data and deploys the connectors to gateway devices. The OT-IT service also provides a developer interface to present available data sources and to receive specifications for workflows that consume data from the data sources. The OT-IT service deploys the workflows to execution locations. The OT-IT service then configures the gateways to send tagged data from the connectors to the workflows for processing.

  • Patent number: 11329920
    Abstract: A method for congestion control in a data communication protocol employing acknowledged communication may include measuring a flight size. A transmission rate may be measured. A trend of the flight size may be determined. A trend of the transmission rate may be determined, and the trend may be derived from a transmission rate gradient calculation, in which either the transmission rate measurements or the transmission rate gradient calculations or both may be filtered to reduce their temporal variability. Whether there is a congestion may be detected according to the determined trend of the transmission rate and the trend of the flight size. Upon detection of the congestion, a change may be made from a current congestion control state to a new congestion control state. Data may be transmitted while respecting a maximum amount of unacknowledged data which the transmitting node may transmit. An apparatus is also disclosed.
