Abstract: A system and associated methods provide solutions for reducing a volume of traffic through a multicast network attributed to repeated maintenance messages, which are required in order to maintain a multicast connection. The system configures provider edge devices to generate and send maintenance messages on behalf of members of a multicast group to establish and maintain the multicast connection and provides options for determining unknown locations of sources and/or subscribers, thereby reducing the overall volume of traffic transmitted over the multicast network.

Abstract: Lease transfer between master and slave replicas is described. A master replicator determines that an initial master replica lease takes effect. On determining that a master replica transfer needs to be performed, sending a transfer preparation message to a target replicator prior to expiration of a current master replica lease. The target replicator locally starts and calculates a new master replica lease and returns a readiness response to the master replicator. The master replicator sends a lease extension message to remaining slave replicators to extend local corresponding leases. After receiving lease extension success responses of a majority of the slave replicators, the master replicator terminates the local master replica lease of the master replicator in advance, and sends a transfer confirmation message to the target replicator. The target replicator validates the new master replica lease to make the target replicator a new master replicator.

Abstract: Reinstating access to a system of an admin whose certificate is invalid or expired is disclosed. When the admin's certificate is expired, the admin may send a request for reinstatement to tenant admins. The voting operation is based on shares of a secret that have been distributed to validators. When the shares are successfully reconstructed to obtain the secret, the voting operation is affirmed or allowed to proceed. If the vote is successful, access for the admin is restored or reinstated.

Abstract: A system and method in a building or vehicle for an actuator operation in response to a sensor according to a control logic, the system comprising a router or a gateway communicating with a device associated with the sensor and a device associated with the actuator over in-building or in-vehicle networks, and an external Internet-connected control server associated with the control logic implementing a PID closed linear control loop and communicating with the router over external network for controlling the in-building or in-vehicle phenomenon. The sensor may be a microphone or a camera, and the system may include voice or image processing as part of the control logic. A redundancy is used by using multiple sensors or actuators, or by using multiple data paths over the building or vehicle internal or external communication. The networks may be wired or wireless, and may be BAN, PAN, LAN, WAN, or home networks.

Abstract: Disclosed are systems and methods for conducting an open conversation user interface and more particularly, to a channel-agnostic user interface experience which can utilize automated background intelligence to simplify the exchange between a software system or member service representative (MSR) and a member, and avoids the need for web-based free form inputs.

Abstract: Lightweight, dynamic mechanisms are provided to support service layer interworking and resource extensibility. For example, one mechanism disclosed herein comprises defining a new service layer (SL) resource definition registration procedure that allows for specifying custom attributes of service layer resources to represent third party technology resources. A second mechanism disclosed herein comprises defining a new SL data model mapping registration procedure to map service layer resources to third party data models and to provide a new interworked retargeting indicator to the service layer. Further, a third mechanism disclosed herein comprises defining a SL generic interworking procedure to intelligently retarget requests toward interworked resources based on the interworked retargeting indicator provided by the data model mapping.

Abstract: An application programming interface (API) proxy intercepts API calls and responses for an application under test in a development environment, simulating (e.g., mocking) rate limiting and throttling behavior, which is otherwise challenging to test. The API proxy receives a API call and, based on a resource limiting parameter (e.g., rate-limiting or otherwise throttling), determines that the API call should be forwarded to the API endpoint. When the API proxy receives another API call from the application, destined for the same API endpoint, the API proxy determines to not forward the second API call, based on the resource limiting parameter (e.g., too soon after the first API call, or requests too much of a computational burden, such as exceeding a resource quota). The API proxy instead returns a throttling response, as would be expected from the API endpoint. The API proxy provides guidance messages for both outgoing calls and incoming responses.

Abstract: Disclosed are controller area network (CAN) nodes and associated methods for communicating through a CAN bus to form a set of communicatively coupled CAN nodes. A CAN node has, and is configured to monitor status of, one or both input and output devices for establishing a vehicle-carried warning system in which an event changing at least one input status causes a CAN message to be broadcast over the CAN bus to change at least one output status. Behavioral equations map input(s) to output(s), thereby resulting in desired actions. Also disclosed is a graphical user interface (GUI) for configuring the behavioral equations.

Abstract: A method includes processing parameter selection inputs corresponding to a threshold correlation rule associated with monitoring a communication network. The method also includes processing node selection inputs. The method further includes causing a list of key performance indicators (KPIs) associated with monitoring the communication network to be populated based on the parameter selection inputs and the node selection inputs. The method also includes processing threshold comparison inputs and breach consistency condition inputs to generate the threshold correlation rule. The method further includes comparing KPI values to a threshold comparison target and causing an alert to be generated indicating that an operating state of the communication network is outside a preset performance level.
