Patent number: 10200297Abstract: Method for queueing packets, each packet of the packets including timing information representing a remaining time until a deadline associated with delivery at its destination; the system including N queues, each queue thereof being configured for buffering at least one packet, the N queues having a cyclic order; the method including keeping track of a pointer, initially pointing to a queue of the N queues; afterwards, repeatedly incrementing the pointer over the N queues, according to the cyclic order, after each passing of a scheduling interval S; enqueueing each packet of the packets in a queue of the N queues, that queue differing from the queue to which the pointer is pointing, based on the packet's timing information and taking into account the cyclic order; and dequeueing enqueued packets from the N queues, while prioritizing dequeueing from the queue to which the pointer is pointing.Type: GrantFiled: March 18, 2016Date of Patent: February 5, 2019Assignee: Provenance Asset Group LLCInventors: Werner Van Leekwijck, Koen De Schepper

Publication number: 20180097739Abstract: A computer-implemented networked application component includes a need parameter manager adapted to regularly determine an instantaneous need of an application for throughput in the network; a credit parameter manager adapted to regularly update a throughput credit built up as a function of throughput difference, i.e. difference between actual data throughput and fair share; and a transport layer application programming interface adapted to alter one or more congestion control parameters in the transport layer of the network depending on the instantaneous need to temporarily receive a throughput above, respectively below, fair share in return for consuming, respectively building up, the throughput credit.Type: ApplicationFiled: September 12, 2017Publication date: April 5, 2018Inventors: Danny De Vleeschauwer, Werner Van Leekwijck

Patent number: 8689246Abstract: A method of providing an Internet protocol television service to a subscriber, and a network element to execute this method. At an acquisition tier, IPTV packets are generated from video stream data of one or more video channels and transmitted to a FCC server cluster at a client-facing tier. IPTV packets associated with one of the one or more video channels selected by the subscriber are delivered from the deliver server cluster to a receiver of the subscriber at a client tier wherein the IPTV packets associated with the one of the one or more video channels are reassembled at said receiver into a coherent video stream. Said generated IPTV packets are routed from a network (5) of a TV broadcaster to networks of one or more TV operators or from a network of a TV operator to networks of one or more TV operators by means of IPTV service routers installed at an intertwine tier arranged between the acquisition tier and the client-facing tier.Type: GrantFiled: August 28, 2007Date of Patent: April 1, 2014Assignee: Alcatel LucentInventors: Werner Van Leekwijck, Toon Coppens, Ing-Jyh Tsang, Tim Gyselings

Patent number: 8688855Abstract: A method is disclosed for performing traffic control in a network, the network comprising at least one link, the method comprising: —measuring the data traffic rate, the data traffic comprising at least one data flow, at at least one link which carries the data traffic; —defining a first and a second threshold value, the second threshold value being larger than the first threshold value; —determining whether the measured data rate is larger than the first threshold value; and if so, starting congestion signaling of a first type, —determining whether the data rate is larger than the second threshold value; and if so, starting congestion signaling of a second type, wherein at least one of the first and the second threshold values are modified over time, based on data traffic information.Type: GrantFiled: November 30, 2009Date of Patent: April 1, 2014Assignee: Alcatel LucentInventors: Josephine Adriaan Werner Van Leekwijck, Koen De Schepper

Patent number: 8588063Abstract: The invention concerns a method of providing resource admission control to packet flows (11, 12, 50) associated with sessions in a communication network (2), and an access controller (21, 22) to execute this method. The communication network (2) handles packets according to priority levels assigned to the packets. The priority levels comprise at least a first and a second priority level wherein the first priority level is higher than the second priority level. First, a packet flow (12) associated with the new session is identified when packets of the packet flow (12) enter the communication network (2). Preferably, the new session is a real-time session. The second priority level is assigned to the identified packet flow and the packet flow (12) is handled according to the second priority level within the communication network (2). A congestion level is measured in the communication network (2).Type: GrantFiled: June 29, 2007Date of Patent: November 19, 2013Assignee: Alcatel LucentInventors: Werner Van Leekwijck, Ali Rezaki, Stefan Custers, Jan Van Den Abeele, Adrianus Van Ewijk

Publication number: 20070127493Abstract: A sending transmission control protocol (TCP) host is used in a first network node (106) to transmit TCP flows over a network segment to a receiving TCP host in a second network node (104). The sending TCP host comprises a TCP convergence module for aggregating all TCP flows through the network segment between the first network node (106) and the second network node (104) into an aggregate TCP flow (112). The receiving TCP host comprises a TCP convergence module for disaggregating the TCP flows from the aggregate TCP flow (112).Type: ApplicationFiled: November 30, 2006Publication date: June 7, 2007Applicant: ALCATELInventors: Ing-Jyh TSANG, Werner Van Leekwijck, Tim Gyselings
