  • Patent number: 9699737
    Abstract: To facilitate increasing power and resource efficiency of a mobile device, in the mobile device, with regard to periodic or one-time data transfers, a communication management component can analyze information comprising data transfer parameter information, including jitter information, associated with each application of a subset of applications used by the device and can desirably schedule and/or bundle data transfers associated with the applications to reduce the number of separate data bursts to transfer that data to thereby reduce use of wireless resources and power consumption by the device. A push notification system can receive respective jitter information associated with each application from the mobile device, and the push notification system can desirably schedule and/or bundle push notifications to reduce the number of separate data bursts sent to the device to reduce use of wireless resources and power consumption by the device.

  • Patent number: 9667516
    Abstract: A system including first and second servers, a domain server, and a route controller is disclosed. The first and second servers are configured to respond to an anycast address and to first and second unicast addresses respectively. The route controller is configured to determine whether the first cache server is non-overloaded, overloaded, or offline, and may instruct the domain name server to provide to provide the second unicast address when the status is overloaded or offline. Routing of the anycast address may be modified so as to direct a content request sent to the anycast address to the second cache server when the status is offline. The domain name server may receive a request for a cache server address and provide the anycast address to the requestor when the status is non-overloaded, and provide the second unicast address when the status is offline or overloaded.

  • Patent number: 9654950
    Abstract: Techniques control traffic transmissions to manage radio resource utilization. When content is being streamed to user equipment (UE) and is at least initially intended to be streamed in real time at a constant bitrate, a communication management component can determine whether the content being transmitted to the UE can be delayed, instead of being transmitted in real time. In response to determining that the content can be delayed, the communication management component can facilitate buffering data and periodically streaming the data to the UE in data bursts to reduce use of UE power and radio resources. When transmitting a visual image to a UE, the communication management component can adjust resolution of a visual image to correspond to screen dimensions of the UE based on information indicating screen dimensions of the UE that can be received from the UE.

  • Publication number: 20160366058
    Abstract: A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network. As such, when the normal traffic peaks or there are link failures or equipment failures, the normal traffic is preferentially transmitted over the bulk-transfer traffic and thus the bulk-transfer traffic dynamically adapts to changes in the available bandwidth of the network. Further, to reduce the impact of dropped packets for the bulk-transfer traffic, the packets of the bulk-transfer traffic are encoded at or near the source component using a loss-resistant transport protocol so that the dropped packets can be reproduced at a downstream link.
