摘要： Disclosed is a method and apparatus for inferring AS paths between two endpoint nodes communicating over a network having a plurality of nodes without having access to the endpoint nodes. The method and apparatus determine routing tables of at least some of the plurality of nodes. A relationship between each node is then inferred from the routing tables. The method and apparatus then determine a path between the two endpoint nodes from the relationship and the routing table determination.

摘要： Method and apparatus for mitigating routing misbehavior in a network is described. In one example, routing protocol traffic is received from a remote router destined for a local router. The routing protocol traffic is parsed to identify a subset of traffic. The subset of traffic is normalized to identify and correct misconfigured routing updates. The routing protocol traffic is provided to the local router. In one embodiment, the subset of traffic is normalized by at least one of detecting and correcting routing protocol semantics, detecting and correcting violations in routing policies, detecting and correcting routing anomalies, or mitigating routing instability.

摘要： Techniques for using controlling traffic transmissions to manage radio resource utilization are presented herein. 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.

摘要： Systems and methods for analyzing mobile device applications within a wireless data network are presented herein. More particularly, described herein is a novel Intelligent Mobility Application Profiling Tool (iMAP) and/or other mechanisms, systems and methods for profiling and benchmarking applications associated with mobile devices in a wireless data network. Various systems and methods described herein expose cross-layer interaction associated with a network device in order to profile an application on the network device with respect to energy efficiency, performance, and functionality. As described herein, radio resource control (RRC) analysis can be performed to infer RRC states associated with a given application, identify tail time, etc. Further, analyzers are employed for various layers, including transmission control protocol (TCP) and/or hypertext transfer protocol (HTTP), as well as to analyze communication bursts associated with a given application. Analysis results are subsequently utilized to deliver application profiling results to a user.

摘要： Detection of user accounts associated with spammer attacks may be performed by constructing a social graph of email users. Biggest connected components (BCC) of the social graph may be used to identify legitimate user accounts, as the majority of the users in the biggest connected components are legitimate users. BCC users may be used to identify more legitimate users. Using degree-based detection techniques and PageRank based detection techniques, the hijacked user accounts and spammer user accounts may be identified. The users' email sending and receiving behaviors may also be examined, and the subgraph structure may be used to detect stealthy attackers. From the social graph analysis, legitimate user accounts, malicious user accounts, and compromised user accounts can be identified.

摘要： A cloud infrastructure that communicates with computing devices is provided. The computing devices install filters on other computing devices that they wish to receive items from including pictures, messages, and documents. The filters include criteria that are evaluated on the computing devices, rather than at a server, to determine if an item may be sent to another computing device. The computing devices may then send items that match the criteria to the cloud infrastructure, and the items may be stored and queued for delivery to other computing devices. The items may be encrypted before being provided to the cloud infrastructure, and decrypted when received by the computing devices.
