Abstract: Described herein are systems and methods for optimizing buffering of streamed content based on upcoming coverage. For example, during a trip, the bit rate for transmission and receipt of streamed content can be dynamically adjusted based on the upcoming coverage such that when the upcoming network coverage is limited, the bit rate of the streamed content can be increased to ensure the buffer is sufficiently large to allow the user to experience (or appear to experience) uninterrupted streaming during the limited network connectivity. The bit rate can be calculated based on calculating a buffer size that can provide content at the play rate for the duration that the device is in a minimal or no network coverage area.

Abstract: A method and a system is disclosed herein for co-operative on-path and off-path caching policy for information centric networks (ICN). In an embodiment, a computer implemented method and system is provided for cooperative on-path and off-path caching policy for information centric networks in which the edge routers or on-path routers optimally store the requested ICN contents and are supported by a strategically placed central off-path cache router for additional level of caching. A heuristic mechanism has also been provided to offload and to optimally store the contents from the on-path routers to off-path central cache router. The present scheme optimally stores the requested ICN contents either in the on-path edge routers or in strategically located off-path central cache router. The present scheme also ensures optimal formulation resulting in reduced cache duplication, delay and network usage.

Abstract: The described systems, methods, and computer-readable storage media manage pooled collections of content items in a content management system. An example system can receive, from a user device, content uploaded to an account at a synchronized online content management system, and cluster some of the content as a collection. The system can receive, from a user, a request to share the collection with a second user having a second account at the content management system. In response to the request, content management system generates a pooled collection from the collection. The system can also transmit an invitation to the second user to join the pooled collection, and, upon acceptance, link the pooled collection to the second user account so that the first user and the second user have access to the persistent pooled collection and have permission to contribute content to the pooled collection.

Abstract: A client updates a display of a user interface associated with a state-based client-server application in accordance with a client-side cache. The server supplies data for a new state and additional data for one or more subsequent states that possibly follow the new state if appropriate one or more operations are performed. When a client request is generated that indicates an operation that causes the application to transition to the new state, the client updates the display in accordance with the data that corresponds to the new state from the client-side cache, if available from the client-side cache. The new state data is available since the server has previously supplied the new state data.

The method includes determining number of computing nodes in the IoT network capable of contributing in processing of a data set. At least one capacity parameter associated with each computing node in the IoT network and each communication link between a computing node and a data analytics system can be ascertained. The capacity parameter can indicate a computational capacity for each computing node and communication capacity for each communication link. An availability status, indicating temporal availability, of each of computing nodes and each communication link is determined. The data set is partitioned into subsets, based on the number of computing nodes, the capacity parameter and the availability status, for parallel processing of the subsets.

The control unit is configured to control the communication unit to receive a low-quality version of a content from the device, store the received low-quality version in the storage unit with the low-quality version of the content associated with an identifier which is identical with an identifier of the content, thereby registering the content, generate, in response to a request from the device, a content list including a thumbnail generated from the low-quality version, transmit the content list to the device, and when the content instructed to be reproduced by the device is not stored in any device on the basis of the content list, control the communication unit to transmit the low-quality version to the device.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for notifying context clients of changes to the current context of a computing device. In some implementations, a context client can register to be called back when the context daemon detects specified context. For example, the context client can specify a context in which the context client is interested. When the context daemon detects that the current context of the computing device corresponds to the registered context, the context daemon can notify the context client that the current context matches the context in which the context client is interested. Thus, context clients do not require the programming necessary to independently obtain context updates and detect changes in context that are relevant or of interest to the context client.

Abstract: A collaborative content management system allows users to access collaborative content items. When a client device accesses a shared collaborative content item, the client device displays a portion of the collaborative content item that falls within a viewport. The client application generates a notification count of notification events associated with content that is contained in the collaborative content item and positioned below the viewport, and the client device displays the notification count in a graphical element adjacent to a bottom viewport edge. A similar process generates a second notification count of the notification events associated with content positioned above the viewport and displays a graphical element with the second notification count adjacent to the top viewport edge. The user can iteratively select one of the graphical elements to move the content of the collaborative content item to a portion corresponding to the next notification event above or below the viewport.

Abstract: A system and method is disclosed that provides fail-save, scalable and clustered correlation of transaction trace data. The transaction trace data is provided by a set of agents injected into application processes and processed by a set of clustered correlation servers. Each agent monitors parts of transaction executions performed by the application process into which it is injected. The agents generate transaction trace data fragments describing the transaction execution part and report those transaction trace data fragments to the correlation cluster. Routing of transaction trace data from agents to correlation servers is performed in a way that transaction data fragments describing a specific transaction are received by one correlation server regardless of the agent sending it. Intermediate nodes may be used to server as proxy between agents and the correlation server cluster to further improve the availability and failure tolerance of the monitoring system.
