Abstract: Automatic switching between two executable programs occurs between a first mode wherein a first executable program is visible and active, and a second mode wherein a second executable program is visible and active. Switching is triggered by detecting that the first executable program has initiated an information processing mode. The first mode is restored upon completion of information processing. In one particular embodiment of the present invention, the first executable program is a browser for requesting, receiving and displaying information obtained from remote information sources, the first mode is a browser mode, and the information processing mode is the requesting by the browser for information.

Abstract: A method for handling multiple accesses to a messaging mailbox prompts the user for action when the status indicates an active session in the mailbox. The method includes receiving a request from a user to access the mailbox to retrieve messages, and determining the session status in the mailbox. If the session status indicates an active session in the mailbox, the user is prompted for action, otherwise, the user is granted access to the mailbox.

Abstract: The invention disclosed herein enables a collection of computers and associated communications infrastructure to offer a new communications process which allows information providers to broadcast information to a population of information consumers. The information may be targeted to those consumers who have a precisely formulated need for the information. This targeting may be based on information which is inaccessible to other communications protocols. The targeting also includes a time element. Information can be brought to the attention of the consumer precisely when it has become applicable, which may occur immediately upon receipt of the message, but may also occur long after the message arrives. The communications process may operate without intruding on consumers who do not exhibit the precisely-specified need for the information, and it may operate without compromising the security or privacy of the consumers who participate.

Abstract: Methods and systems for controlling data flow between a sender and a receiver include communicating credit lists to the sender. The credit lists include credits indicative of receive buffer sizes accessible by the receiver and capable of receiving data. The sender transmits data packets to the receiver. The data packets are preferably no greater in size than the credits specified in the credit list. When the sender uses all of the credits, the sender preferably refrains from sending data packets to the receiver until the supply of credits is replenished by the receiver. Because data flow between the sender and the receiver is regulated using credits, the likelihood of data overflow errors is reduced and communication efficiency is increased.

Abstract: A method for scheduling performance measurements to be collected over a network, each measurement target having an associated measurement interval specifying an approximate time between measurements. The method includes identifying a cost for each target and sorting the targets into a plurality of time periods. Each period has approximately the same total cost of measurement targets. Targets having similar measurement intervals are grouped together within each of the time periods and assigned to a time range within the period. The method further includes sorting the measurement targets within each time range to provide a generally even load balance across the time range. A system for scheduling performance measurements is also disclosed.

The plurality of interfaces emulate a single high-speed interface. According to an embodiment of the present invention, a first identifier is assigned to the first interface and the second interface at the first device. According to another embodiment of the present invention, one of the plurality of interfaces is selected to transmit a packet of data.

Abstract: An accelerated access system for a computing device, in which the computing device is connected to a first data network, such as the Internet, via a second data network such as a wireless telecommunication network. The system comprising a server for downloading data from the first data network before that data has been requested by a user of the computing device and a cache for storing the downloaded data. For example, during browsing of the Internet by a user of the computing device the server downloads data linked to an Internet site being displayed by the computing device for storage in the cache. Then when a user subsequently requests the data stored in the cache it appears on the screen of the computing device faster than it would take to access it from the Internet.

Abstract: The present invention is method and system capable of delivering video across the Internet using the hypertext transfer protocol. Client objects periodically request to view a uniform resource locator that is aliased to a servlet. For each request, the servlet retrieves and delivers a video image to the requesting client object. The invention can simultaneously deliver images to a variety of client objects, regardless of whether they are requesting the images at the same rate.

Abstract: A guest station on a foreign network is provided IP access by the foreign (i.e., hosting) network without changes to the guest station, including settings for IP address, next-hop-router (gateway), and netmask. An access router automatically detects guests and their home-IP-address and assigns a local care-of address to every guest. For outgoing traffic, the router replaces the guest's original/home IP address with the care-of address, and the reverse is performed for incoming traffic. IP traffic may thus be initiated, and responses received at the temporary current location without having to change its IP address.

Abstract: A system and method for controlling usage of a particular software program in a computer network environment is disclosed. The invention operates by controlling the throughput of the software as it executes on a server computer. In particular, the invention monitors the number of active requests to the software. If the number of active requests exceeds a predefined number, the software throughput on the server (e.g., requests completed per minute) is artificially restricted. As such, the present invention continues to allow further connections to the software but intentionally restricts further use by inhibiting the throughput for all connections to the software. Preferably, the present invention continues to allow the predefined number of active requests to be exceeded, but as more requests are made, the overall performance of software progressively degrades.

Abstract: The routing address lookup problem is one of the major bottlenecks in high performance routers and deals with forwarding of packets. In the Internet domain it is known as “IP address lookup problem.” This invention provides a new and easy way to preprocess routing tables which gives efficient packet/message forwarding and is feasible in the time and the space it consumes. More precisely, the method for m-bit IP addresses gives a balanced trade-off between performing a binary search on T with O(log|T|) accesses, where |T| is the number of entries in T, and executing a single access on a table of 2m entries obtained by fully expanding T. While the prior art starts out from space-efficient data structures and aim at lowering the O(log|T|) access cost, the invention starts out from the expanded table with 2m entries and aim at compressing it without an excessive increase in the number of accesses.

Abstract: A uniform mechanism for building containment hierarchies separates the code/method which actually perform the containment insertion operations on the components from the specification of the containment and then provides an automatic way of obtaining and executing that code when containment hierarchies need to be created. The mechanism consists of an abstract syntax for describing the containment relationships, processing mechanism for creating the containment mechanism, and a registry containing the mechanisms for implementing specific containment policies. Having this abstraction allows an application programmer to be able to construct hierarchies of objects without having to be concerned about the specific details of how that containment is performed. In fact, the details may be deferred until run-time (and even downloaded from elsewhere).

Two variables representing the common output flow are measured and the control instructions are determined by a fuzzy-logic controller. Application to controlling a set of compressors.

Abstract: A recognition system of the self-organizing artificial neural network type is arranged to classify input data according to stored categories which have been determined by a training process. In the training process the initial category representations are selectively iteratively updated in response to a series of training patterns and in accordance with a competitive learning routine. this routine uses measures of category utilization based on the proportion of all inputs received over a representative period, particularly long term utilisation and short term utilization, to ensure that all available categories will be used and that the system is stable. The training rate which determines the amount of modification to a category representation at an up-date is local to each category and is based upon the maturity of the category and on the similarity measure between the internal representative pattern and the training input so that the training duration can be minimized.
