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.

Abstract: Example methods disclosed herein to prioritize anomalies in a communication network include classifying respective nodes in the communication network as normal, abnormal or indeterminate based on measurements received for the nodes. Disclosed example methods also include selecting a subset of the nodes classified as abnormal to be root cause abnormal nodes representing sources of the anomalies in the communication network, respective ones of the root cause abnormal nodes being abnormal nodes identified in the communication network and determined to have respective sets of direct descendent nodes having majorities of nodes classified as abnormal or indeterminate. Disclosed example methods further include combining respective anomaly sizes and anomaly scopes determined for the respective ones of root cause abnormal nodes based on the measurements to determine respective rankings for the root cause abnormal nodes, and outputting the respective rankings to prioritize the set of root cause abnormal nodes.

Abstract: A method, computer readable medium and apparatus for managing a degree of parallelism of streams are disclosed. For example, the method analyzes wireless traffic to determine a profile of the wireless traffic, determines an amount of available processing resources, and manages the degree of parallelism of streams based on the profile and the amount of available processing resources in a probe server.

Abstract: A system for passive estimation of throughput in an electronic network is disclosed. The system may include an plurality of mobile devices configured to operate in the network and may further include an electronic data processor. The processor may be configured to access flow records for data flows associated with the mobile devices during a predetermined time interval. Additionally, the processor may be configured to annotate the flow records with an application field and a content provider field. The processor may also be configured to determine a flow type of each data flow based on the application field and the content provider field of the flow records. Furthermore, the processor may be configured to generate a throughput index that only includes non-rate-limited flow types. Moreover, the processor may be configured to estimate maximum throughput for each data flow having non-rate-limited flow types in the throughput index.

Abstract: A computer implemented method includes identifying a universal resource locator and characterizing a traffic pattern associated with the universal resource locator. The traffic pattern can include referrer information, referring information, advertising network relationship information, and any combination thereof. The method can further include classifying the universal resource locator into a risk category based on the traffic pattern.

Abstract: A system and method to use network flow records to generate information about changes in network routing and to understand the impact of these changes on network traffic. The inferences made can be determinative, if sufficient information is available. If sufficient information is not available to make determinative inferences, inferences may be made that narrow the range of possible changes that may have occurred to network traffic and the underlying network.
