Abstract: Systems and methods provide for Selective Tracking of Acknowledgments (STACKing) to improve buffer utilization and traffic shaping for one or more network devices. A network device can identify a first flow that corresponds to a predetermined traffic class and a predetermined congestion state. The device can determine a current window size and congestion threshold of the first flow. In response to a determination to selectively track a portion of acknowledgments of the first flow, the device can track, in main memory, information of a first portion of acknowledgments of the first flow. The device can exclude, from one or more buffers, a second portion of acknowledgments of the first flow. The device can re-generate and transmit segments corresponding to the second portion of acknowledgments at a target transmission rate based on traffic shaping policies for the predetermined traffic class and congestion state.

Abstract: In one embodiment, a device obtains telemetry data indicative of channel usage by a plurality of Bluetooth Low Energy (BLE) tags. The device also obtains tag characteristic data indicative of one or more characteristics of the BLE tags. The device determines that usage of a particular channel by the BLE tags exceeds a predefined threshold, based on the obtained telemetry data. The device selects a subset of the plurality of BLE tags, based on their one or more characteristics indicated by the obtained tag characteristic data. The device instructs, for each of the selected subset of BLE tags, the selected BLE tag to increase an interval of time between BLE advertisements sent by the selected BLE tag.

Abstract: Generating and enforcing tenant-specific policies within a container includes, applying a first policy for a specific operational parameter when a software package that is running within a container and that is utilized by a plurality of tenants is leveraged by a first tenant of the plurality of tenants. A second policy is applied for the specific operational parameter when the software package is leveraged by a second tenant of the plurality of tenants.

Abstract: Systems, methods, and computer-readable media for orchestrating data center resources and user access to data. In some examples, a system can determine, at a first time, that a user will need, at a second time, access to data stored at a first location, from a second location. The system can identify a node which is capable of storing the data and accessible by a device from the second location. The system can also determine a first service parameter associated with a network connection between the device and the first location and a second service parameter associated with a network connection between the device and the node. When the second service parameter has a higher quality than the first service parameter, the system can migrate the data from the first location to the node so the device has access to the data from the second location through the node.

Abstract: A network node in a service function chaining system receives multiple media streams of a media session between endpoints. Each media stream is encapsulated with a service header indicating a service function path and a session identifier. The network node determines that multiple service functions connected to the network node perform a particular service function in the service function path. The network node provides all of the media streams of the media session to a single service function instance to ensure that the media session is processed by the single service function.

Abstract: A gateway device is configured to operate as a network function in a service function chain and is connected to a plurality of network connected devices. The gateway device receives a service function chain packet that includes a request to obtain data from one or more of the plurality of network connected devices. The gateway device obtains the data from the one or more network connected devices and modifies the service function chain packet to include the data obtained from the one or more network connected devices. The gateway device sends the service function chain packet that has been modified to include that data obtained from the one or more network connected devices along the service function chain.
