Abstract: In one embodiment, a client device queries a location server using a client-selected interface for content retrieval from a content distribution network (CDN), and receives a location attribute from the location server based on a location of the client device. The client device then presents the location attribute to a CDN selector within a first content retrieval request, and may receive a redirection from the CDN selector to a selected content source based on the location attribute. As such, the client device may then initiate a second content retrieval request to the selected content source. In another embodiment, a CDN selector receives a content retrieval request from a client device, and determines that the content retrieval request contains a location attribute indicating a location of the client device. Based on the location attribute, the CDN selector selects a content source, and redirects the client device to the selected content source.

The user may be able to define rules and settings that limit the scope and timing of the push notifications that can be received, and the third party may determine if notifications received from the proprietor or merchant meet these rules and settings before pushing the notifications to the user device and user.

Abstract: Systems and techniques are described for optimizing communications between a client and a server. Specifically, in some embodiments, an executing script on a client can send a resource request to a server. In response, the server can send an optimized version of the resource back to the client. The client can then reconstruct the resource from the optimized version of the resource.

Abstract: A system and method that enables two or more hosts so that they can share a resource, such as a display. Client allocates a portion of the resource to each of the eligible hosts. This allocated size is negotiable among host(s) and the client. Client may request the hosts to scale down/up resource utilization based on the allocated portion of the resource being shared. This helps keep the client implementation simple. In this case, client maintains the allocation vector for each host. This allocation vector is used to keep track of the resource sharing. While this is a preferred approach, it is possible that “intelligent” client may actually modify resource utilization for a given host based on the negotiated allocation.

Abstract: A segment based switching architecture with hybrid control providing flow control in software defined networking (SDN). An SDN controller controls top tier macro-flows and virtual segment backbone connections in a network, and an SDN network edge device controls and manages micro-flows that are attached to the SDN network edge device. The SDN network edge device controls and manages the micro-flows locally without using a southbound API. The SDN network edge device learns flow information such as source information and incoming port information for all unknown micro-flows belonging to defined segments, and builds a virtual segment topology database for each segment. The SDN network edge device employs flow computation algorithms and micro-flow management in a distributed fashion. The virtual segment backbone connections are naturally exposed to the SDN controller through provisioning.

Abstract: A streams manager determines when congestion is happening or is predicted to happen in a streaming application, and in response, unfuses one or more operators in the streaming application from its processing element. The selection of which operators to unfuse in which processing elements is made using suitable unfuse criteria, which may include selecting operators that do not maintain state, selecting operators that have a threaded port or queue preceding the operator, selecting operators at natural boundaries, and inserting queues before operators to be unfused. Once one or more operators are unfused, the streams manager can take action to enhance performance of the unfused operator(s). For example, the streams manager can allocate additional resources to the unfused operators, can create clones of unfused operators that process tuples in parallel, can move one or more unfused operators to a public cloud, etc.

Abstract: Systems and methods are provided for obtaining look-ahead segments for a streaming media item during playback such that the viewer can easily skip to the look-ahead segments without experiencing any substantial interruption or delay in playback. In general, a streaming media source begins streaming a media item to a streaming media client for playback. In one embodiment, the streaming media client selects one or more segments of the media item as one or more look-ahead segments to prefetch from the streaming media source. Then, while the media item is being streamed to the streaming media client for playback, the streaming media client prefetches the one or more look-ahead segments of the media item from the streaming media source. The look-ahead segments are thereafter utilized to enable the viewer to skip ahead in playback without experiencing a substantial interruption or delay in playback.
