Abstract: Application usage is profiled based on application streaming. Code pages of multiple applications are streamed from a server to multiple client computers (endpoints) for execution. The streaming of the code pages is monitored, and usage data is collected such as which pages are streamed to which endpoints, under what circumstances and when. By referencing the streamed code pages and the underlying source code, the code pages are mapped (at least approximately) to corresponding application features. The collected usage data usage and the relevant mapping are analyzed, to create application usage profile data for streamed applications. The application usage profile data can include such information as how often, when, where and by whom application components are being executed, as well as which components cause errors, are most popular, confuse users, etc.

Abstract: Described is a technology by which additional network communications capacity is provided to an oversubscribed base network where needed, through the use of dynamically provisioned communications links referred to as flyways. A controller detects a need for additional network communications capacity between two network machines, e.g., between two racks of servers with top-of-rack switches. The controller configures flyway mechanisms (e.g., one per rack) to carry at least some of the network traffic between the machines of the racks and thereby provide the additional network communications capacity. The flyway mechanisms may be based on any wireless or wired technologies, including 60 GHz technology, optical links, 802.11n or wired commodity switches.

Abstract: Methods, computer readable media, and apparatuses for balancing the number of transaction requests with the number of applications running and processing information for those transaction requests are presented. According to one or more aspects, a message queue receives one or more messages, each including a transaction request, from a computing device.

The applications process the transaction requests and send a response for each of the transaction requests to the message queue. The message queue sends the response back to the computing device.

Abstract: An approach for caching potentially repetitive message data in a publication/subscription messaging environment is provided. Specifically, when a message is received on a broker system from a publisher system, the broker system analyzes the message for potentially repetitive data. Once such a set of data has been identified, a unique identifier/key corresponding thereto will be sent back to the publisher system and the set of data will be stored in a (data) cache. Upon receipt, the publisher system will cache/store the unique identifier in a (key) cache. Then, when the publisher system generates a future message that would contain the same set of data, the publisher system will substitute the unique identifier (as retrieved from the key cache) for the set of data to yield an abbreviated/truncated message.

Abstract: In a system for streaming data over a network, the type and rate of streaming are automatically varied based on available network bandwidth. Video media is transcoded into different bit rate encodings that are divided into segment files. Segments are sent from a network-aware adaptive streaming (NAAS) server and reassembled and presented to a media player at a client device. The system may download additional segment files ahead of time from multiple NAAS servers to increase throughput. A playback status (“bookmark”) may be maintained to keep track of what the user has viewed and to allow the user to continue playing from where the user left off. The user may continue watching from the bookmark point on the same device or on a different device.

Abstract: Techniques are disclosed for a client device to stream a user-selected media file from a content server. The client device may create a playlist of dynamic virtual chunks to represent a single media stream file on a streaming media server. The playlist itself may be generated from an index in the header of a given stream defining what chunks, or segments of multiplexed audiovisual content, are present within that stream. The playlist of dynamic virtual chunks provides the playback engine on the client device with a list of individual files that may be requested from the streaming server independently of one another, despite the stream being stored on the server as a single media stream file.

Abstract: A server-client system or architecture that allows datacast applications to reliably transport data objects from a network server over a unidirectional packet network (“datacast network”) to one or more clients, each of which may be listening to the packet stream at different times. The invention allows the clients to listen intermittently to the datacast, yet still receive all of the data objects published by the server in a timely manner, and in a way that is more optimal in terms of client resource use. This ensures that listening clients can receive a complete set of the data objects broadcast while being able to conserve client processing and power resources by not requiring continuous listening by the client to the datacast.

Abstract: Systems and methods for providing the progressive download of media content using techniques that preferentially identify and use periods of surplus network capacity to maintain the content delivery. A buffer of a receiving system is maintained and pre-filled with enough content to bridge playback intervals where a network is unable to deliver content as fast as it is played out. When no surplus network capacity is available, a user requesting content may be given the option to continue the delivery in the background so that the content may be played at a later time. The user may then resume their playback experience once the content has been completely delivered using surplus network capacity as it becomes available. A first portion of a content file may be pre-delivered to the receiving system so that users may consume the first portion content while the buffer is pre-filled.

Abstract: Systems and methods for providing the progressive download of media content using techniques that preferentially identify and use periods of surplus network capacity to maintain the content delivery. A buffer of a receiving system is maintained and pre-filled with enough content to bridge playback intervals where a network is unable to deliver content as fast as it is played out. Content delivery does not impact other users' applications and use of the network and its resources since content is only sent when surplus network capacity exists in the network. When no surplus network capacity is available, a user requesting content may be given the option to continue the delivery in the background so that the content may be played at a later time. The user may then resume their playback experience once the content has been completely delivered using surplus network capacity as it becomes available.

In contrast, if the load balancing apparatus determines that the path control identifier is not contained, the load balancing apparatus sends the message to the relay device specified in accordance with a predetermined condition.
