Patent number: 9021018Abstract: A method for supporting the selection of communication peers in an overlay network, wherein a multitude of communication peers participate in the overlay network by providing certain pieces of information, and wherein at least one peer-to-peer server—tracker—is provided that maintains a database of the participating communication peers and the information possessed by them, wherein the tracker, upon receiving a query regarding a specific piece of information from a communication peer—requesting client—, answers the query by providing the requesting client a list that includes a subset of all communication peers possessing the requested piece of information, includes providing a network entity located such that it receives messages directed from the requesting client to the tracker, wherein the network entity stamps topological location information of the requesting client into any of the messages directed from the requesting client to the tracker. Furthermore, a corresponding system is disclosed.Type: GrantFiled: October 29, 2010Date of Patent: April 28, 2015Assignee: NEC Europe Ltd.Inventors: Sebastian Kiesel, Hans-Joerg Kolbe, Rolf Winter

Publication number: 20140192646Abstract: A method of policing network traffic based on congestion on a flow-based programmable switch, such as an OpenFlow switch is provided. The method polices congestion-causing flows in a network by detecting congestion at a flow-based programmable switch on the network. Once congestion has been detected, the method identifies one or more flows that are causing the congestion at the flow-based programmable switch, and penalizes the flows that were identified as causing congestion. A flow-based programmable switch including a data plane having input ports, output ports, and forwarding rules that map packets received on an input port to an output port based on a packet matching a rule in the forwarding rules is also described.Type: ApplicationFiled: September 6, 2011Publication date: July 10, 2014Applicant: NEC EUROPE LTD.Inventors: Faisal Ghias Mir, Marcus Brunner, Rolf Winter, Dirk Kutscher

Patent number: 8769124Abstract: For allowing a high degree of resource consumption within a network a method for operating a network is claimed, wherein at least one end user device is connected to an access network, wherein the method is characterized in that the at least one end user device or an application on the end user device queries at least one network element of the access network and/or at least one network element attached to the access network about low layer parameters information for optimizing connection and/or protocol parameters after having received the queried low layer parameters information. Further, a network is claimed, preferably for carrying out the above mentioned method.Type: GrantFiled: September 28, 2010Date of Patent: July 1, 2014Assignee: NEC Europe Ltd.Inventors: Rolf Winter, Hans-Joerg Kolbe

Patent number: 7958001Abstract: Stored in a computer are scores related to answers given by human representatives of organizational units in response to defined questions. For the organizational units, total scores and weighted total scores are calculated. The weighted total scores are calculated by adding up weighted maximum scores assigned to the questions, the weighted maximum scores depending on the respective organizational unit and the respective question. Competence levels of the organizational units are calculated by scaling the total scores of the respective organizational unit to a scale of competence reaching from zero to a maximum competence. The maximum competence corresponds to the weighted total score calculated for the respective organizational unit. The computer generates a graphical representation of the competence levels for multiple organizational units of a particular organization.Type: GrantFiled: April 28, 2004Date of Patent: June 7, 2011Assignee: Swiss Reinsurance CompanyInventors: Rico Abbadessa, Christoph Ziegler, Andreas Machler, Lars Andersson, Rolf Winter, Vladimir Bezouska

Publication number: 20110044342Abstract: A method for populating a forwarding information base of a router of an autonomous system (AS) in the Internet's Default Free Zone (DFZ), wherein the forwarding information base contains a multitude of entries, each entry mapping a destination prefix to at least one route to reach the destination prefix, is characterized in that for each prefix advertised to the router, the autonomous system (AS) the advertisement was received from is determined, and that a decision is made whether to include the prefix into the forwarding information base of the router or not, wherein in the decision the autonomous system (AS) and/or predefined characteristics of the autonomous system (AS) the prefix is learned from is/are considered. Furthermore, a corresponding router for deployment in autonomous systems (AS) in the Internet's Default Free Zone (DFZ) is disclosed.Type: ApplicationFiled: June 9, 2009Publication date: February 24, 2011Applicant: NEC Europe LtdInventor: Rolf Winter

Patent number: 4907137Abstract: An adjustable neck is provided for adjusting a lamp, in particular a lamp plugged onto a low-voltage rail, in as many alternative directions as possible. The adjustable neck is mounted between a clamping socket of the lamp and the replaceable incandescent body or bulb. The adjustable neck includes several joint members, each consisting of a ball portion that can be plugged into a corresponding joint seat portion of a next adjacent joint member and held there by a friction fit. The incendescent body can be surrounded by a lamp shade provided with ventilating slots. The clamping socket is embodied such that a positive anchoring is achievable even in the case of larger, heavier lamps.Type: GrantFiled: May 25, 1988Date of Patent: March 6, 1990Assignee: Rolf WinterInventors: Klaus Schladitz, Rolf Winter

Patent number: 4625266Abstract: A nose edge of a step of a stairway is to be marked by a lighted strip which can be seen by a person going upstairs and by a person going downstairs. This is to be accomplished by a nosing bar assembly which comprises a single illuminating device and in which transparent covering means for such illuminating device are not liable to be strongly damaged or soiled. For this purpose covering for the illuminating device is so arranged below the level of the tread surface of the step that points of the surface of the covering means can be seen from a space which is disposed above the tread surface of the step and which in the downstairs direction is defined by a vertical plane which contains the front boundary line of the tread surface.Type: GrantFiled: February 8, 1985Date of Patent: November 25, 1986Inventor: Rolf Winter
