Abstract: A method and an apparatus of transmitting power saving-poll (PS-Pall) for use in a wireless network are provided. The method includes a terminal in a wireless communication system determining PS-Poll transmission priorities of terminals based on identifiers of the terminals having downlink data to receive, monitoring to detect the PS-Polls of the terminals having downlink data to receive, and transmitting, when the PS-Poll of the terminal with a priority followed right by the priority of the terminal is received, the PS-Poll after expiry of an arbitrary backoff timer.

Abstract: Systems and methods are provided for ranking linked documents (e.g., web pages on the Internet) by modeling how users are expected to use links between the documents. One embodiment is a system that includes a memory and a controller. The memory stores probabilities for documents that each indicate a likelihood of using a link at a document to view another document. The controller is able to assign an initial value to each document, and for each document that has a value greater than a cutoff amount, to diffuse the value from the document to other documents based on the probabilities. The controller is further able to rank the documents based on an amount of value that was diffused from each document, and to process the documents based on their ranks.

Abstract: A computer implemented method for user-enhanced ranking of messages, the method comprising: receiving a datastream, the datastream comprising a message generated by an end-user, an identifier of an earlier message and an attribute defined by the end-user, the earlier message being stored in a computer-based database (4) comprising a collection of messages interrelated by a collection of directional links, storing the message in the computer based database (4) as an additional message of the collection of messages, generating a link in the computer-based database as an additional link of the collection of links, the additional link pointing from the additional message to the earlier message, storing the attribute in the computer-based database (4) in association to the additional message, and computing a link-based rank for the earlier message as a function of the collection of links and the attribute associated to the additional message.

Abstract: A method for user-enhanced ranking of information objects, comprising: generating a graphical user-interface (40) on a display (13), the graphical user-interface comprising a graph (41), wherein the graph comprises a plurality of icons each representing an information object of the collection of information objects and a plurality of connectors connecting the icons, each connector representing at least one link of the collection of links, modifying the graph by generating an additional connector between the icons in response to graph modification commands received from a user-controlled interaction means, storing an additional link in the database (21) as a function of the additional connector, wherein the additional link interrelates information objects represented by he icons connected by the additional connector, computing a link-based rank for an information object of the collection of information objects as a function of the additional link and the collection of links.

Abstract: A method for control of congestion of traffic, being categorized according to a number of layers (L), in a network node, comprises a step of monitoring the amount (n(t)) of incoming flows to this node such that, based upon this amount (n(t)) of incoming flows and on a current number of accepted layers (l(t)), a next number of accepted layers (l(t+1)) for entry into said node is determined by consultation of an action table (T). In an enhanced embodiment the action table is adjusted based on the observed traffic during an observation period.

Abstract: The invention concerns a method for testing and predicting the behaviour of a computer network. Said method consists in; a) storing a representation of the network, including routers, and a use configuration of the network including traffic classes each associated with sources; b) on the basis of the initial conditions (400), iteratively applying an additive increase and multiplicative decrease model of the traffic evolution (410, 420), to simulate an evolution of rates in the network, storing each time a set of class or source rate variables; and c) if the iteration at step b) produces a periodical orbit (430), returning to a set of class or source rate variables already encountered, examining the series of routers encountered, as responsible for losses to evaluate the rate obtained by each class or source (450).
