Patent number: 8861396Abstract: The invention relates to a method and devices for a packet switching system for traffic-load dependent power reduction in packet switching systems. In order to reduce the power consumption of a packet switching system, the method comprises the steps of determining a traffic rate for incoming data packets at the upstream packet processing device; processing the incoming data packets; transmitting an indication of the determined traffic rate from the upstream packet processing device to the downstream packet processing device at a time prior to the time that the processed data packets for which the traffic rate has been determined are transmitted to the downstream packet processing device; and adjusting available packet processing resources at the downstream packet processing device based on the received traffic rate indication.Type: GrantFiled: April 22, 2010Date of Patent: October 14, 2014Assignee: Alcatal LucentInventors: Ralph Schlenk, Christian Hermsmeyer

Patent number: 8594046Abstract: The invention concerns a method of performing an intra-segment handover (HO) of a mobile station (MS) from a source access point (AP1) of a tree-structured segment (S1) of an Ethernet-compliant telecommunication network to a target access point (AP2) of said segment (S1), as well as a switch (SW-123) to support the execution of this method. After establishing contact between the mobile station (MS) and the target access point (AP2), the mobile station (MS) sends an update entry request addressed to the segment gateway switch (GW). The update entry request is received by a switch (SW-123) positioned in the tree structure of the segment (S1) hierarchically above the source and target access points (AP1, AP2) and below the segment gateway switch (GW). The switch (SW-123) checks whether its forwarding database contains a first entry comprising an address of the mobile station (MS) received by means of the update entry request.Type: GrantFiled: March 18, 2010Date of Patent: November 26, 2013Assignee: Alcatel LucentInventors: Ralph Schlenk, Christian Hermsmeyer, Armin Dekorsy

Patent number: 8483241Abstract: The invention includes a method and apparatus for determining the performance of a virtual concatenation group (VCG) signal transporting a client signal over a transport network. A method includes collecting a plurality of performance monitoring indicators associated with a plurality of VCG member signals of the VCG signal, synchronizing the performance monitoring indicators with respect to each other, combining the synchronized performance monitoring indicators to form VCG-level performance monitoring indicators, calculating VCG-level performance monitoring primitive measurements based on the VCG-level performance monitoring indicators, and processing the VCG-level performance monitoring primitive measurements to determine VCG performance.Type: GrantFiled: February 15, 2007Date of Patent: July 9, 2013Assignee: Alcatel LucentInventors: Christian Hermsmeyer, Angel Molina, Wolfgang Thomas

Patent number: 8374177Abstract: In order to provide a network element for switching time-division multiplex signals in a transport network, which allows higher capacity at moderate equipment costs, the network element has a number of input ports (I; IO1-IO8), a number of output ports (O; IO1-IO8) and a switch fabric ( ) SF; 58) interconnecting the input and output ports (IO1-IO8). The switching fabric ( ) SF; 58) is a cell based switch comprising one or more switch modules ( ) SE1-SEn) which are adapted to switch fixed-length cells on the basis of addresses contained in cell headers of the cells. The input ports (I) contain a segmentation device (11) for segmenting an input time-division multiplex signal into fixed-length cells and assigning address information to each cell. The output ports (O) contain a reassembly device (14) for reassembling cells received from said switch fabric (SF; 58) into an output time-division multiplex signal. The address information contains a fabric address (H1, H2) and a TDM address (P0, P1).Type: GrantFiled: December 3, 2009Date of Patent: February 12, 2013Assignee: Alcatel LucentInventors: Werner Beisel, Christian Hermsmeyer, Joerg Pleickhardt
