| 20080259793 | Network traffic control in peer-to-peer environments - A method and an electronic unit are disclosed for controlling traffic on a network, especially for controlling peer-to-peer related traffic. A filter unit is intercepting messages related to peer-to-peer application from a network line, irrespective of the messages' destination, A control logic then manages a request represented by an intercepted message subject to its content and subject to peering specific information. | 10-23-2008 |
| 20080269957 | Method and apparatus for determining wagon order in a train - The present invention relates to a method and apparatus for determining the order of wagons in a train. The invention configures a plurality of wagons of a train to sense at least one environmental condition that the wagons are respectively exposed to when the train is moving. The invention configures the wagons to generate a corresponding announcement message in response to a change in state of the environmental condition. The invention configures the first wagon of the train to listen for the announcement message generated by any of the plurality of wagons. The invention configures the first wagon to compute a sequence of the announcement messages from an order in which the wagons have been heard. | 10-30-2008 |
| 20080271146 | Identifying a distributed denial of service (DDoS) attack within a network and defending against such an attack - The invention provides methods, apparatus and systems for detecting distributed denial of service (DDoS) attacks within the Internet by sampling packets at a point or points in Internet backbone connections to determine a packet metric parameter. The packet metric parameter which might comprise the volume of packets received is analysed over selected time intervals with respect to specified geographical locations in which the hosts transmitting the packets are located. The expected behaviour can be employed to identify traffic distortions revealing a DDoS attack. In a complementary aspect, the invention provides a method of authenticating packets at routers in order to elevate the QoS of authenticated packets. This method can be used to block or filter packets and can be used in conjunction with the DDoS attack detection system to defend against DDoS attacks within the Internet in a distributed manner. | 10-30-2008 |
| 20080275885 | INDEX SERVER SUPPORT TO FILE SHARING APPLICATIONS - An index server support for file sharing applications is disclosed. A way of retrieving an index server includes sending a request for investigating a hierarchical structure of index servers in a network to a known index server, intercepting the investigation request by the first index server that becomes aware of the investigation request, notifying an originator of the investigation request of the intercepting index server identity, dropping the intercepted request is dropped by the intercepting index server. The originator of the investigation request then registers the intercepting index server as addressee for future file querying requests. | 11-06-2008 |
| 20090064177 | METHOD FOR DATA DELIVERY IN A NETWORK - The present invention relates to a method of delivering data from a sender application to at least one receiver application that are arranged in a protocol stack comprising: underlying the sender application a sender messaging layer and a sender transport layer, and underlying the receiver application, a receiver messaging layer and a receiver transport layer, wherein the sender transport layer and the receiver transport layer are coupled by way of a network layer, the method comprising the steps of: incorporating a sender intermediate layer between the sender messaging layer and the sender transport layer and a receiver intermediate layer between the receiver messaging layer and the receiver transport layer; configuring the interface characteristics of the intermediate layers to be the same as for their corresponding transport layers; creating a sender queue in a non-volatile data storage component of the sender intermediate layer and a receiver queue in a non-volatile data storage component of the receiver intermediate layer, storing the data to be sent from the sender application to the receiver application in the sender queue, and transmitting the data stored in the sender queue to the receiver queue via the sender transport layer and the receiver transport layer. | 03-05-2009 |
| 20110007663 | Determining Placement of Nodes Within a Wireless Network - A system of nodes including processors within a wireless sensor network includes an arrangement of the nodes with data connections therebetween within the wireless sensor network, wherein the data connections are limited to a set of distinct, non-intersecting paths, wherein each source node of the nodes is connected with a root nodes of the nodes by at least a predetermined number of the paths | 01-13-2011 |
| 20110061054 | METHOD AND APPARATUS FOR SCHEDULING EVENT STREAMS - Apparatus and method for scheduling event streams. The apparatus includes (i) an interface for receiving event streams which are placed in queues and (ii) a scheduler which selects at least one event stream for dispatch depending on sketched content information data of the received event streams. The scheduler includes a sketching engine for sketching the received event streams to determine content information data and a selection engine for selecting at least one received event stream for dispatch depending on the determined content information data of the received event streams. The method includes the steps of (i) determining content information data about the content of event streams and (ii) selecting at least one event stream from the event streams for dispatch depending on the content information data. A computer program, when executed by a computer, causes the computer to perform the steps of the above method. | 03-10-2011 |
