Abstract:
A method and apparatus for managing communication congestion for internet of things (IoT) devices are provided. An exemplary apparatus includes an IoT device that includes a data transfer controller configured to create a sensor message and dispatch the sensor message to a pipeline processing application in a cloud. A data store is configured to store the sensor message in a cache if it cannot be sent due to communication issues. A data backlog transfer controller is configured to send the sensor message from the data store when the communications issues are not present.
Abstract:
A technique is provided for providing a multi-level data rate control for a service flow within a wireless network, the technique including: sending, by a network convergence service to one or more data providers, a first level data rate limit for a service flow, receiving, by the network convergence service from the one or more data providers, data for the service flow, applying, by the network convergence service, a second level data rate limit for the service flow, and forwarding, by the network convergence service, data for the service flow within the second level data rate limit.
Abstract:
Methods, systems, and computer readable media can be operable to facilitate dynamic packet prioritization for delivery of content to multiple devices. Methods, systems, and computer readable media described herein are operable to prioritize packet delivery to a plurality of client devices based upon feedback received from the client devices, wherein the feedback includes buffer status information associated with the client devices. The rate of transmitting packets to a client device having a stressed buffer may be increased, while the rate of transmitting packets to one or more other client devices may be decreased. Buffer status information may be received periodically or conditionally at a central device in the form of feedback messages output from one or more client devices.
Abstract:
In an example, a method of processing data includes transmitting data over a network at a first bit rate, identifying a reduction in a network link rate of the network from a first network link rate to a second network link rate, and in response to identifying the reduction in the network link rate, determining a recovery bit rate at which to transmit the data over the network, where the recovery bit rate is less than the second network link rate. The method also includes determining a buffering duration based on a difference between a time of the identification of the reduction in the network link rate and an estimated actual time of the reduction in the network link rate, and determining a recovery rate duration during which to transmit the data at the recovery bit rate based on the recovery bit rate and the buffering duration.
Abstract:
A system and method is provided for sending congestion notification messages through L3 networks. For example, a data packet is received at a first switch (533) in a first fabric block (510) of an L3 network, and the first switch performs source MAC tagging of the data packet. The data packet is then forwarded to a second switch (555) in a second fabric block (560) of the L3 network, and the source MAC tag is maintained by the second switch (555) and any intermediate switches (544). The second switch (555) determines, in response to receiving the data packet, whether it is congested, and generates a notification message (585) if it is congested. The notification message (585) is L2 forwarded to the first fabric block (510), and further forwarded from the first switch (533) to a source (511) of the data packet using ACL matching.
Abstract:
Described is a method for estimating throughput between first and second communication devices, the method comprising: determining maximum bottleneck throughput of a communication link between the first communication device and a third communication device, wherein the communication link between the first and third communication devices applies a common access network as between a communication link between the first and second communication devices; determining Round Trip Time (RTT) between the first and second communication devices; transmitting packet by applying User Datagram Protocol (UDP) from the third communication device to the first communication device; measuring packet loss rate associated with the transmitted packet by monitoring sequence number of the packet; and translating measured packet loss rate to Transmission Control Protocol (TCP) throughput according to maximum bottleneck throughput and RTT.
Abstract:
There is provided a method of controlling a rate at which content data is received at a receiver over a network, wherein the receiver has caused a first stream of real-time communication event data to be received at the receiver, and a second stream of content data to be received at the receiver, the method comprising steps of: dynamically measuring network conditions of the network based on the real-time communication event data; and limiting the rate at which the content data is received at the receiver based on the dynamically measured network conditions.
Abstract:
Content is received within a network by a content receiver based upon fetch requests by the content receiver to a content source, where the fetch requests for content are based upon a first adaptation logic scheme to fill a buffer of the content receiver at a selected rate and to download segments of content at selected encoding rates. A network priority is detected at the content receiver that includes an observed download rate at the content receiver that is greater than a fair share rate for other content receivers in the network. Fetch requests for content are revised in response to detection of the network priority, where the revised fetch requests are based upon a priority adaptation scheme that results in at least one of filling the buffer at a faster rate and downloading segments of content at higher encoding rates compared with the first adaptation logic scheme.
