Abstract: Systems and techniques for adaptive dataflow transformation in edge computing environments are described herein. A transformation compatibility indication may be received from a device. A set of transformations available for use by the device connected to the network may be determined based on the transformation compatibility indicator. The set of transformations may be transmitted to the device. A value may be determined for an operating metric for an edge computing node of the network. The edge computing node may provide a service to the device via the network. A transformation request may be transmitted to the device based on the value. The transformation request may cause the device to execute a transformation of the set of transformations to transform a dataflow of the service. The adaptive dataflow transformations may be continuous with changing predicted values of operating metrics.

Abstract: An agent interfaces with a sending computing device and a receiving computing device to automatically adjust one-way or two-way real-time audio and real-time video transmission parameters responsive to changing network conditions and/or application requirements. The agent incorporates a reinforcement learning model that adjusts transmission parameters to maximize an expected value of a sum of future rewards; the expected value of the sum of future rewards is based on a current state of the sending computing, a current action (e.g. a current set of transmission parameters) at the sending computing device and a reward provided by the receiving computing device. The reward is representative of a user-perceived quality of experience at the receiving computing device.

Abstract: Systems and methods for implementing stateful services using cloud-based resources are described. A server computing system determines existence of a first volume based on a launch of a first instance by an auto-scaling group (ASG). The first volume is to have a resource tag having a value similar to a value of a resource tag of the ASG. The first volume was previously attached to a second instance terminated by the ASG. Based on a successful determination of the existence of the first volume, the server computing system attaches the first volume to the first instance. Based on a failed determination of the existence of the first volume, the server computing system generates a second volume, attaches the second volume to the first instance, and set a resource tag of the second volume to a value similar to the value of the resource tag of the ASG.

Abstract: Containerized workflow engines executing metadata for user-defined applications are described. A system utilizes user selections for configuring a user-defined application to identify application definition metadata. The system stores the application definition metadata for the user-defined application into a persistent storage.

Abstract: The present disclosure relates to systems and method for accelerated network impairment mapping. An example method may involve receiving, from a subset of downstream devices on a network, telemetry data associated with the performance of the subset of downstream devices. The example method may also involve determining, based on the telemetry data, that an impairment exists at a first device of the subset of downstream devices. The example method may also involve requesting, based on the determination that the impairment exists at the first device, telemetry data from one or more neighboring devices to the first device. The example method may also involve determining, based on the telemetry data from the one or more neighboring devices, that an impairment also exists at a second device of the one or more neighboring devices. The example method may also involve determining a lowest common ancestor to the first device and the second device on the network.

Abstract: One exemplary system described herein can detect a first request associated with invoking a serverless function in a sequence of serverless functions. In response, the system can deploy a primary container and a secondary container in a cloud computing environment. The primary container can execute the serverless function and transmit a second request for invoking a second serverless function in the sequence. The secondary container can intercept the second request and generate a modified second request. The secondary container can then transmit the modified second request to a destination other than an endpoint of the second serverless function, where the destination can cause the second serverless function to be executed in response to receiving the modified second request.

Abstract: A method for an application executed on a user terminal to retrieve a data stream from a server including a network access point in a transportation vehicle to receive a request from the application to the server to set up a connection between the application and the server, set up a first connection between the network access point and the application, and set up a second connection between the network access point and the server. The network access point requests and receives a first subset of the data stream from the server via the second connection and stores the first subset in a buffer store of the network access point. The network access point receives a request from the application to the server to send a second subset of the data stream to the application. The method sends the second subset of the data stream via the first connection.

Abstract: This technology enables prioritization of Multiple Stream Reservation Protocol (“MSRP”) transmissions in Audio Video Bridging (“AVB”) virtual local area networks (“VLANs”). An AVB switch receives a status from listener devices, associates a state with each of the statuses indicating whether each listener device is active or in-active, and stores each state in a database. For each listener device, a queue of MSRP protocol data unit (“PDU”) packets exists to be transmitted to the listener device. The AVB switch searches the database for listener devices with an active state, searches the queue for each active listener device for packets associated with an active state, and transmits the packets associated with the active state to each active listener device. Subsequently, the AVB switch searches each listener device's queue for packets associated with an in-active state and transmits the packets associated with an in-active state to each listener device.

Abstract: Systems and methods are included for detecting driving based on user-specific models for driving detection, and restricting access to an application of the user device while a user is driving. A management agent installed on the user device can collect data from sensors in a user device and provide the data to a management server, which can build a user-specific model for driving detection for that user. The management agent can then use that user-specific model for detecting when the user is driving. When the agent determines that the user is driving, it can enforce a driving policy that limits access to applications and delay or modify notifications generated by applications.
