Abstract: A method for improving the performance for a streaming service by link-adaptation and power-control in a wireless packet network such as an Enhanced General Packet Radio Services (EGPRS) cellular network is described. In particular, the effects of a combined link adaptation and power control scheme (referred to as an error-based scheme) for achieving a target error rate, which is non-zero but low enough so that limited retransmission and error concealment techniques are effective, is presented.

Abstract: In a data conversion system, a WSP request for obtaining WWW contents of a Web server is sent from a terminal device to a WAP proxy and constraint information of images of the terminal device is added to header information of the request. Upon reception of the constraint information, the WAP proxy converts the WWW contents obtained from the Web server into data based on the constraint information, so that the WWW contents converted into the data are transmitted to the terminal device.

Abstract: A method and apparatus for enhancing the performance of a network by performing selective spoofing, i.e., determining whether or not to spoof a connection. Selective spoofing provides the ability to discriminate among different connections, only allocating TCP spoofing resources to those where spoofing will improve performance and assigning spoofing parameters based on the specific applications using the connections. The selective spoofing is applicable to a wide variety of communication links, including both slow and fast links, high latency links, and links with low and high error rates. The selective spoofing functions are used either alone or together with other performance enhancing features. Those features include spoofing the conventional TCP three-way handshake, local data acknowledgement, multiplexing multiple connections across a single connection, data compression/encryption, prioritization, and path selection.

Abstract: A method and apparatus for exception handling in a multi-processor environment are described. In an embodiment, a method for handling a number of exceptions within a processor in a multi-processing system includes receiving an exception within the processor, wherein each processor in the multi-processor system shares a same memory. The method also includes executing a number of instructions at an address within a common interrupt handling vector address space of the same memory. The number of instructions cause the processor to determine an identification of the processor based on a query that is internal to the processor. Additionally, the method includes modifying execution flow of the exception to execute an interrupt handler located within one of a number of different interrupt handling vector address spaces.

Abstract: A method and apparatus for creating and posting media is provided. For example, the invention allows a user to quickly create, signal process, encode, and transfer media files to a server for storage, posting, distribution, and retrieval. Thus, media such as audio, video, display, photo, spreadsheet, Web Clips, and HTML pages can be combined into a media file for uploading to a server and accessed from listings posted at web sites. In accordance with embodiments, a user downloads and installs a plug-in at the user's client computer. The user then registers and logs onto the server to perform various tasks. For example, the user can create a combined audio and photo media file at the client computer, in accordance with server based control parameters received from the system server. The plug-in then allows the user to perform digital signal processing and encoding of the media file at the client computer.

Abstract: An application program interface (API) for use in monitoring a computer application executed on a computer system. The API includes software code added to the computer application for assigning a single general reference to characteristic transactional information associated with a transaction to be executed by the computer application. The API further includes an agent for marking the time at which the software code is executed and tagging that time with the characteristic transactional information as the characteristic transactional information is being currently processed by the computer application. The API and its method of operation provide precise measurement of the latency of information flowing through the computer system while being uncomplicated in design and implementation, minimally invasive, and highly scalable.

The method generally includes transmitting a disconnect request message to the first device in response to a data link establish request and transmitting a request for connection to establish link message to the second device upon one of expiration of an awaiting-response timer, receiving a disconnect mode message from the second device and receiving an acknowledgement message from the second device.

Abstract: A method and apparatus are provided for handling events received at a media streaming server. Server sockets configured to receive events are divided into collections and registered with a polling object. Each collection shares a processor thread for detecting events. Each socket is associated with an event consumer object that is notified when an event is received at the socket. The event consumer objects invoke task objects to handle the events. Task objects are queued in a task queue and execute using a pool of processor threads. Event consumer objects are derived from an abstract base consumer class that defines a common interface. Subclasses of the base consumer class are configured for different types of events that may be received (e.g., connection requests, media streaming commands, media data, media stream quality reports). Specific event consumer objects are instantiated from the subclasses to provide implementations of the common interface.

Abstract: An automatic distributed partitioning system (ADPS) determines which unit exposes an interface. The ADPS detects a reference to an interface. For the interface, the ADPS assures that the unit that exposes the interface is identified. In some embodiments, a data structure such as a hash table associates interfaces with identified units. An interface wrapper for the interface stores the identity of the unit that exposes the interface, as well as information about the interface and a reference to instrumentation. When a client unit calls a member function of an interface, the interface wrapper intercepts the call and invokes the instrumentation. The instrumentation performs an operation such as profiling the application or classifying a unit. The ADPS detects when an interface is undocumented, and handles undocumented interfaces without invoking the full instrumentation capabilities of the ADPS.

Abstract: A method for automatically tracking application and content usage is disclosed. According to an embodiment of the present invention, a method first recites the step of accessing an application interface (API) call with a parameter specifying a first portion of content to be measured. For example, the amount of time for which the portion of content is used is measured. Next the method recites, in response to the accessed call, measuring usage for the first portion of content. Then, the method recites continuing to access API calls specifying additional portions of content to be measured until the program making the calls finishes execution. In this fashion, content usage is tracked. Application developers may determine, from the content usage, where users are getting stuck in a game or what segments of an electronic document are being viewed.
