Abstract: Systems and methods are provided for personalizing new song suggestions for a user. A plurality of users provides thumbs up and thumbs down ratings for a pair of songs (song A and B). A first aggregate rating for song B is calculated based on ratings given to song A by all of the users that gave a like rating to song A. Similarly, a second aggregate rating is calculated for song B based on ratings given to song B by all users that gave a dislike rating to song A. Then a user that has not previously rated song B, supplies a rating for song A. A prediction is performed of how the user will rate song B based on the user's rating of song A. For example, the first aggregate rating for song B is used if the user rated song A positively.

Abstract: Internet protocol packets are statelessly identified as associated with a particular session-instance by identifying a key, or session-instance identifier, within the data (or payload) portion of a user plane packet. This identifier is specific to the session-instance and remains constant throughout the session-instance. Using this stateless identification, transmitted user plane packets are automatically routed at the transmission speed of the transmission link using a method that automatically balances the analysis processing load between network probes. The load is balanced by routing the user plane packet to a network probe that is either already analyzing the session-instance or by routing the user plane packet to a system that has processing capacity to analyze a new session-instance. The network probe then analyzes the user plane packet and the session-instance to measure the quality of the user experience of the session-instance and performance of the network.

Abstract: The systems and methods discussed herein provide for a predictive monitoring technique to suppress data exchange between the client device or devices and the monitoring device or devices. Regression-based intelligent predictions systems executed both by the client device or devices and the monitoring device or devices perform identical prediction algorithms. If the predicted metric values and the actual measured metric values on the client device are very close, then the client device may skip transmitting the measured metric values to the monitoring device; similarly, if a measured metric value is not received by the monitoring device, then the monitoring device knows that the measured metric was similar to the predicted metric on the client device, and accordingly may utilize the predicted metric on the monitoring device. Because transmission of the measured metric values may be skipped, network traffic and interface and processor utilization is significantly decreased.

Abstract: The described captive portal techniques cause client devices to render and display designated web pages. One designated web page may be different than a requested web page such as when a client is not authorized to access the requested page and is instead caused to display a login portal. The captive portal may modify the designated web page to ensure that relative links lacking base domains now have specified base domains pointing to an authorized web server. The modified content is sent from the captive portal to the client device for display. Client web browser security measures related to redirection messages are thereby bypassed and load on the captive portal is minimal. Another designated web page may be the same as the requested web page such as when the requested page is an authorized page even for non-logged in clients. Authorized pages may be modified to add a login link.
