Abstract: A server and plural terminal devices form a network. Messages are transferred among the terminal devices via a plurality of virtual communication spaces formed on the network. The transmitted and received messages are displayed on a display device of each terminal device together with the message sender identifying information. The identifiers of members utilizing the virtual communication spaces and character-train information corresponding to the respective identifiers are stored in a display name management table. When an identifier and a message are sent from a terminal device, the server converts the identifier into a character train by means of the display name management table and sends the character train to the terminal devices.

Abstract: In a content retrieval device, a browser section generates a retrieval request for sub-content data to be retrieved presently. A protocol control section determines which communication path between a first communication path or a second communication path should be used prior to the reception of the sub-content data which is specified by the browser section. If the protocol control section determines that the first communication path is to be used, a first communication control section receives the sub-content data which is specified by the browser section from a content server. If the protocol control section determines that the second communication path is to be used, a second communication control section receives the sub-content data from the content server. In this way, the content retrieval device can select a suitable connection method prior to the reception of data.

The data storage device also includes a control module to control the transmission of data from the memory to the power integrated network and the storage of data received from the power integrated network in the memory. A power module in the data storage device receives power from the power integrated network. The power module converts the power received from the power integrated network to a voltage level that may be used to power the data storage device.

Abstract: A system and method is provided for seamlessly switching between different network access technologies without interrupting active network applications or sessions. A Network Access Arbitrator (NAA), which contains a virtual network adapter driver, resides between a Data Link Layer and a Network Layer of the standard OSI-7 Layer Protocol Stack for controlling necessary switching between different network access technologies. Since all network applications are controlled by layers residing on or above the Network Layer, all applications using network services provided by the Network Layer will continue their active network sessions or applications without disruption, as the NAA switches between different network access technologies.

Abstract: A broadcast system, method and apparatus providing content on demand. In one embodiment, the disclosed broadcast system includes a server that broadcasts meta-data to a plurality of clients. The meta-data describes a plurality of data files that are to be broadcast or potentially broadcast later by the server. Each client receives the broadcasted meta-data from the server and updates and maintains a local meta-data table and a content rating table. Based on the meta-data, previous access habits of the user and optional user classifications, the client system selectively receives and/or stores the data files that are later broadcast by the server. In one embodiment, the client systems transmit back to the server ratings of each one of the data files described by the meta-data based on the user's previously accessed data files and optional user classifications. The server then determines the data files to be broadcast and the broadcast schedule based on the ratings received from the clients.

Abstract: On a computer cluster, a distributed object, called a console, manages all interactions with users and manages error reporting. The console provides a simple synchronous call interface that does not use any network semantics. This allows all layers of the software to use the console. User interaction and error reporting is enhanced by an error stack, included in the console. The error stack can be maintained on a per client context basis. When an error occurs, each layer of software can add details to the error stack. The result is the relaying meaningful error messages to the user.

Abstract: The present invention involves reducing the amount of unsolicited e-mail. In one embodiment, a method for automatically detecting unsolicited electronic mail from a mailer and automatically notifying facilitators of the mailer of the unsolicited electronic mail is disclosed. In one step, an electronic mail message is received from the mailer. It is automatically determined if the electronic mail message is probably unsolicited. A check for an open relay in routing information of a header of the electronic mail message is performed. The facilitating party of the mailer is determined. Information relating to the electronic mail message is automatically reported to the facilitating party.

Abstract: The admission control algorithm implements measurement-based connection admission control using effective envelopes of an arriving traffic aggregate and the service curves of the corresponding departing traffic aggregate. The approach provides the statistical service guarantees to a variety of service classes. According to the admission control algorithm, arriving traffic is admitted if the sum of the effective envelopes of the arriving traffic entering a network and admitted traffic currently in the network is less than or equal to the service curve.

Abstract: A method is presented that includes generating a content identifier for at least one article. The content identifier identifies the article. Also, determining if at least a portion of the at least one article is present on at least one device based on the content identifier. The at least one portion of the at least one article is stored if the at least one portion of the at least one article is determined to be not present on the at least one device. Also presented is a method including requesting at least one article by a content identifier representing the article. The at least one article is determined if it is present on at least one device based on the content identifier. At least one portion of the at least one article is returned if the at least one portion of the at least one article is determined to be present on the at least one device.

Abstract: When XML data stored in a server are to be updated, a client displays an update form by using update form display means. The update form includes paths, methods and values (after addition or change) of elements of XML data. Then, the paths, methods and values are inputted into input boxes in the update form. Then, an update instruction is generated on the basis of the information inputted into the input boxes, and is transferred to data update mean in the server. Thus, the client need not to convert the XML data into the DOM object, and a memory capacity of the client is reduced, because the update instruction includes only the paths, methods and values.

Abstract: A data transmission method includes the steps of generating a data characteristic table and a retrieval data table in a memory area on a server side (S102, S103); converting items of the tables into serial form and combining them to generate transmission data (S104); attaching control data corresponding to the characteristics of the transmission data (S108); transmitting the data to a client machine (S110); regenerating the data characteristic table and the retrieval data table in a memory area on the client side (S203); and reading predetermined data from the regenerated table (S204). This method increases the data transmission rate, decreases the response time, and increases the efficiency of use of the database.
