  • Patent number: 10587536
    Abstract: Techniques for improved handling of queues of data units are described, such as queues of buffered data units of differing types and/or sources within a switch or other network device. When the size of a queue surpasses the state entry threshold for a certain state, the queue is said to be in the certain state. While in the certain state, data units assigned to the queue may be handled differently in some respect, such as being marked or being dropped without further processing. The queue remains in this certain state until its size falls below the state release threshold for the state. The state release threshold is adjusted over time in, for example, a random or pseudo-random manner. Among other aspects, in some embodiments, this adjustment of the state release threshold addresses fairness issues that may arise with respect to the treatment of different types or sources of data units.

  • Patent number: 10567294
    Abstract: Techniques for controlling packet transmission levels in a multi-hop network may be performed in a distributed manner. Load-control functionality may be distributed among a plurality of nodes within a network, allowing such nodes to send feedback to upstream nodes, and receive feedback from downstream nodes. In an example, received packets are measured, such as by summing sizes of received packets over time, to determine a received traffic-level. Transmitted packets are measured, such as by summing sizes of transmitted packets over time, to determine a transmitted traffic-level. Feedback may be sent to at least one source of the received packets based at least in part on the received traffic-level and the transmitted traffic-level. The feedback may indicate a desired rate for the sender to transmit. A node may receive data from upstream node(s) and from an internal device, such as a metrology unit.

  • Patent number: 10560537
    Abstract: Technologies are disclosed for local and distributed function based dynamic traffic management for network services. A service host executes a network service and provides a service framework that includes one or more handlers. When a request is received for the service, one of the handlers assigns a classification to the request. The handler then provides the classification to a dynamic function based traffic controller. The controller determines whether the network service is to process the request based on the classification of the request, metrics associated with the network service, and a local traffic management policy. If the controller determines that the network service is not to process the request, the request is rejected. Otherwise, the request is passed to the network service for processing. Metrics can also be provided from the service host to a distributed performance monitoring system for use in managing network traffic at a fleet level.

  • Patent number: 10542057
    Abstract: A method of multicasting real-time video is described. The method begins by establishing a multicast network of machines capable of ingress, forwarding and broadcasting traffic, together with a mapping infrastructure. The multicast network preferably comprises a portion of an overlay network, such as a content delivery network (CDN). A video stream is published to the multicast network by (a) using the mapping infrastructure to find an ingress node in the multicast network, and then receiving the video stream from a publisher at the ingress node. One or more subscribers then subscribe to the video stream. In particular, and for subscriber, this subscription is carried out by (a) using the mapping infrastructure to find an egress node for the requesting client, and then delivering the video stream to the subscriber from the egress node. Preferably, the publisher and each subscriber use WebRTC to publish or consume the video stream, and video stream is consumed in a videoconference.

  • Patent number: 10447418
    Abstract: A method and apparatus for controlling delay over a data path in a device for transporting Ethernet packets over an optical transport network. The device is configured to receive an incoming clock signal having a first frequency and an incoming data signal and to output an outgoing clock signal having a second frequency and an outgoing data signal. One or more delays over the data path in the device are measured in a predetermined measurement period. A phase adjustment amount is determined based on the one or more measured delays over the data path in the predetermined measurement period, and based on the determining phase adjustment amount, a phase of the outgoing clock signal is adjusted by a phase locked loop in such a way that the delay over the data path in the device is substantially equal to a fixed delay value.

  • Patent number: 10432798
    Abstract: A speed tier based pricing scheme is utilized to increase average revenue per user (ARPU). To offer a speed tier based pricing scheme, the radio environment at a location of the UE can be analyzed to determine the speed tiers that can be offered to the user. In one aspect, an outer-loop scheduler can be utilized to allocate radio bearers to the UE based on a target data throughout associated with a user-selected speed tier. The priority of the non-guaranteed bit rate (GBR) bearers of the UE can be dynamically adjusted to track the target data throughput. In another aspect, a throttling function can be implemented to limit the data throughput of the UE to the target data throughput.

  • Patent number: 10425788
    Abstract: The present disclosure relates to a clustering approach for sensor nodes of a wireless sensor network. This clustering approach, equal distance different members, balances the power burden amongst sensor nodes by deriving an optimal number of sensor nodes at each segment of a length. To this end, the present disclosure describes a linear wireless sensor network wherein the distance between adjacent cluster heads is equal while the number of and distance between sensor nodes in each cluster is different. A power consumption model is derived to aid in the determination of the optimal number of sensor nodes within each cluster. Following evaluation of the cluster approach in comparison with previously described approaches, the present disclosure is observed to improve network longevity and reduce power consumption by deliberately increasing the density of sensor nodes nearest a base station.

  • Patent number: 10409628
    Abstract: Generally described, the present application relates to systems and methods for the managing virtual machines instances using a physical computing device and an offload device. The offload device can be a separate computing device that includes computing resources (e.g., processor and memory) separate from the computing resources of the physical computing device. The offload device can be connected to the physical computing device via a interconnect interface. The interconnect interface can be a high speed, high throughput, low latency interface such as a Peripheral Component Interconnect Express (PCIe) interface. The offload device can be used to offload virtualization and processing of virtual components from the physical computing device, thereby increasing the computing resources available to the virtual machine instances.

  • Patent number: 10390070
    Abstract: A method for adaptive video transmission based on channel capacity. As part of the method, a first wireless display capacity in a proximity of a wireless display source device is determined. The first wireless display capacity is based on information that is received from a wireless channel scan associated with a formation of a (P2P) peer-to-peer group that includes the wireless display source device and a wireless display. Further, the video bit rate of one or more devices with wireless display connections in the proximity is determined, the video bit rate of the one or more devices with wireless display connections in the proximity is compared to the wireless capacity, and, based on the comparing, a video bit rate of the wireless display source device is set. A second wireless display capacity in the proximity of the wireless display source device is determined based on a wireless channel scan of a wireless channel to determine wireless display connections in the proximity.
