Abstract: Providing data to portlets can include a step of registering a plurality of portlets to determine a type of data required by the portlets. The registering can establish a portlet context for handling future data requests for the portlets. A type of information associated with one of the portlets can be determined. A data acquisition process can be initialized to obtain the determined type of information from a data source. A data request can be received for data of the determined type from the associated portlet. Data can be acquired from the data source using the initialized process. The data request can be responded to using the acquired data. In one embodiment, the acquisition of data from the source and the updating of the portlets can occur asynchronously, where a cache is used to temporarily store data acquired from the data source that is used to update the portlets.

Abstract: Systems and methods of removing a tunnel created when a client having an active IP session with a first portal point in a first subnet of a network, disconnects from the first portal point and reconnects to a second portal point in a second subnet of the network, the client maintaining an IP address assigned to it by the first subnet, embodiments of the method including the steps of determining whether data is scheduled to transfer from the second portal point to the client; if no data is scheduled, disconnecting the client from the second portal point; deactivating the IP session, whereby the IP address is released to the first subnet; removing the tunnel; reconnecting the client to the second portal point; and activating a second IP session between the client and the second portal point, whereby a second IP address is assigned to the client by the second subnet.

Abstract: A server migration tool used to construct data center migration scenarios allowing for a user to rapidly manipulate a large number of input parameters required to describe a transformation from one data center configuration to a new data center configuration. The tool then performs the transformation and allows the user to interact with new data center configuration to understand its performance. A novel parameterization, speed independent service demand (SISD), greatly facilitates scaling performance metrics between different hardware platforms.

Abstract: A method for distributing cached messages in a load-balanced publish/subscribe messaging network using an HTTP redirect in response to an HTTP client message request is disclosed. The redirect response including a URI at which a next message in a list of sequential messages slated for the HTTP client per the request is located, wherein the HTTP client uses the URI to automatically iterate through and receive the entire list of sequential messages.

Abstract: A system generates a web page that includes a plurality of embedded data windows. The system receives a request for the web page from a browser and in response generates and displays a frame for the web page on the browser. The frame includes holes for the embedded data windows. The system also receives a data streaming request for each of the embedded data windows and determines if the data streaming requests are thread-safe. For all the data streaming requests that are thread-safe, the system generates a parallel thread to fetch the data for each corresponding data streaming requests. When the data has been fetched for a particular data streaming requests, the data is rendered and streamed to the browser where it is displayed in place of the hole by the browser.

Abstract: A sensor-Net system includes sensor nodes which are in intermittent operation so as to save power by repeating activated state and inactivated state at a regular interval. Synchronization of time in the system is executed by aligning to the intermittent operation of the sensor nodes. A management server issues a setTime command for configuring the time to each gateway node at a specified interval. Each router node sets or corrects the time of it based on the time received from the gateway node and thereafter turns ON the time configuration flag for each sensor node in order to expand the setTime command to all of its sibling sensor nodes. The router node, upon reception of a polling, which is a command request, from the sensor node, obtains the time at that time, then uses the time to generate a setTime command to transmit to that sensor node.

Abstract: Disclosed are apparatus and techniques for escalating an instant messaging (IM) session between two or more users to an audio session so that a communication device (by one or more users) that will optimize the audio session is selectively and intelligently utilized. In one embodiment, if an IP (Internet Protocol) phone is connected to the computer on which an IM session is being escalated, the IP telephone may be used instead of the computer device's own soft telephone so as to maximize audio clarity and quality. In another embodiment, a user's cell phone may be utilized for a mobile user who is using a laptop that is not coupled to an IP telephone or who is communicating from a hotel room in which a telephone call is typically more expensive than a cell phone call. Numerous embodiments for optimizing such audio sessions are described herein.
