Abstract: Wireless video download rates are optimized by receiving, at a system with a computer that includes a processor and memory, a request to provide a piece of video content over a wireless network. The processor of the computer is used to determine whether to provide the video content at a first option that is as soon as possible or at a second option over a specified interval T. The interval T is calculated as a time for a destination device to download the video content at a rate level higher than encoding for the video content requires. Upon determining to provide the video content over the interval T, the video content is provided over the wireless network over the interval T to a client device that requested the piece of video content.

Abstract: A method includes receiving, at a device from a content source, a portion of a particular chunk of media content a particular quality level. The method includes receiving, at the device, network data about network conditions associated with the device in response to receipt of the portion. The method includes making, at the device, a determination based on the network data whether to download the particular chunk at a first quality level that is higher than the particular quality level based on the particular quality level and the data. The method includes, in response to the determination indicating to download the particular chunk at the first quality level: sending, to the content source from the device, a request for the particular chunk at the first quality level, and replacing the portion with the particular chunk at the first quality level.

Abstract: A crowd-sourced mobile messaging spam detection and defense system includes an application running on a mobile device. The application uses an unwanted message detection algorithm to analyze and classify messages as potential unwanted messages. The potential unwanted messages are presented to a user for confirmation that the messages are unwanted messages. In response to confirmation, the mobile device transmits a notification to a virtual machine associated with the user. The virtual machine uses the notification to update the unwanted message detection algorithm which may then be transmitted to the mobile device. The virtual machine may also transmit the notification to a global virtual machine. The global virtual machine may use the notification to update a set of classification rules maintained by the global virtual machine and transmit the set of classification rules as necessary to the multiple virtual machines for use in updating the unwanted message detection algorithm.

Abstract: A network includes a cache server and a network aware server that operates to determine an optimization between a cost of retrieving content from a communication network and a cost of caching content at the cache server. The optimization is determined as a minimum of a sum of a transit cost, a backbone cost, and a caching cost. The transit cost includes a money cost per data unit. The backbone cost includes a money cost per data unit and time unit. The caching cost includes a money cost per server unit. In response to determining the optimization, the network aware server sends a content identifier to the cache server, and the cache server receives the content identifier, determines a source of a content item, and if the source is the same as the content identifier, then cache the content item.
