Abstract: Systems and methods for autonomous program management include a device which receives a request from a client responsive to execution of a script on the client. The request may include a location corresponding to the script and an identifier. The device may determine that activity of the client is activity of an autonomous program based on a comparison of the location to a reference being generated by the device for the client and determined using the identifier from the request. The device may block a subsequent request from the client to a server responsive to the determination.

Abstract: Presented are methods for converting a multicast media stream to unicast segments, for delivery over generic IP networks such the Internet. The unicast segments can be converted back again to a multicast stream that is identical to the original multicast stream closer to the consuming client device. Information required to regenerate a multicast stream from the generated unicast segments that is identical to the original multicast stream is also encoded into the file name of the generated unicast segments. Additionally, RTP header information from the multicast stream that is not required when the unicast segments are generated are stored in files linked to the generated unicast segments, enabling the multicast stream that is regenerated to be identical to the original multicast stream even at the RTP level.

Abstract: The present disclosure relates to methods and systems for providing access to external client machine via a domain name system (DNS) of an internal network. A distributed DNS service maintains distributed DNS entries as external clients log on and/or log off of the internal network. In this manner, internal systems within the internal network may access distributed client devices via the internal network DNS.

Abstract: Some embodiments provide a method for quantifying quality of several service classes provided by a link between first and second forwarding nodes in a wide area network (WAN). At a first forwarding node, the method computes and stores first and second path quality metric (PQM) values based on packets sent from the second forwarding node for the first and second service classes. The different service classes in some embodiments are associated with different quality of service (QoS) guarantees that the WAN offers to the packets. In some embodiments, the computed PQM value for each service class quantifies the QoS provided to packets processed through the service class. In some embodiments, the first forwarding node adjusts the first and second PQM values as it processes more packets associated with the first and second service classes. The first forwarding node also periodically forwards to the second forwarding node the first and second PQM values that it maintains for the first and second service classes.

Abstract: A method performs large-scale data processing in a distributed and parallel processing environment. The method defines application-independent map and reduce operations, each invoking one or more library functions that automatically handle data partitioning, parallelization of computations, and fault tolerance. A user specifies a map operation, which calls one or more of the application-independent map operators to perform data read and write operations. A user also specifies a reduce operation, which calls one or more of the application-independent reduce operators to perform data read and write operations. The method executes application-independent map worker processes. Each map worker process executes the user-specified map operation to read designated portions of input files and store intermediate data values in intermediate data structures. The method also executes application-independent reduce worker processes.

Abstract: Real-time cell performance information for each of cells in a mobile communication network, referred to herein as network topology information, is produced using IP addresses of data sessions in the cells, measured performance of the data sessions, and IP address to cell identifier mappings. The network topology information may be used to determine, in real time, a level of monitoring for each of the cells. The network topology information may be used to determine, in real time, performance of video streams in each cell. The network topology information may be used to determine, in real time, that a cell is experiencing a performance anomaly. Determinations made using the network topology information may be used to configure, maintain, and optimize the performance of the mobile communication network.
