Patent number: 9680880Abstract: The invention includes a method and apparatus for configuring legacy nodes to support multicast functions. The method includes determining, in response to a request for a first user device to join a multicast group, whether any node in a multicast path between the first user device and a second user device comprises a legacy node and forming, in response to a determination that a node in the multicast path is a legacy node, a message adapted for configuring the legacy node to start forwarding multicast traffic from a first interface to a second interface of the legacy node. The legacy node may be configured to stop forwarding multicast traffic from the first interface of the legacy node to the second interface of the legacy node. The legacy node may be configured to start/stop forwarding traffic from one or more input interfaces to one or more output interfaces.Type: GrantFiled: July 11, 2006Date of Patent: June 13, 2017Assignee: Alcatel-Lucent USA Inc.Inventor: Dennis Bijwaard

Patent number: 8767733Abstract: The invention includes a method and apparatus for dynamically establishing a multicast group. The method includes receiving, from a first user device, a request to establish a multicast group including a plurality of parameters adapted for establishing the multicast group, obtaining a multicast address for the multicast group, and establishing the multicast group using the assigned multicast address and the parameters. The parameters include at least one multicast group definition parameter and at least one multicast session description parameter. The multicast address and at least a portion of the parameters are adapted for being provided to a second user device to enable the second user device to dynamically join the multicast group.Type: GrantFiled: June 27, 2012Date of Patent: July 1, 2014Assignee: Alcatel LucentInventors: Dennis Bijwaard, Arjan deHeer, Dirk-Jaap Plas

Patent number: 8737397Abstract: The invention includes methods for converting between a plurality of unicast sessions and a multicast session. A method for converting from unicast sessions to a multicast session includes receiving a request for establishing a unicast session for delivering content to a first client device, generating a multicast session establishment message adapted for establishing a multicast session with the client device for delivering the content to the client device, and generating at least one multicast session join message for the other client devices, the at least one multicast session join message adapted for enabling the other client devices to join the multicast session. The multicast session establishment message is generated using a threshold number of unicast sessions. A method for converting from a multicast session to a unicast session is provided. A method for converting from a plurality of unicast sessions to a plurality of multicast sessions is provided.Type: GrantFiled: February 4, 2011Date of Patent: May 27, 2014Assignee: Alcatel LucentInventors: Dennis Bijwaard, Ko Lagerberg

Patent number: 8392583Abstract: A method for controlling distribution of a content stream in a communications network, comprising the steps of: storing session state information about existing communication sessions within the network, receiving a request (15) for transmission of a content stream to a requesting network client (4), determining that an existing session includes the requested content stream, determining that a receiver (1) of said content stream in said existing session has a network location correlated with a network location of the requesting network client, selecting a relay network element (5) capable of servicing said correlated network locations, and setting up at least one communication session for streaming said requested content stream to both the requesting network client (4) and said receiver (1) of the content stream in the existing session through the relay network element (5).Type: GrantFiled: October 20, 2008Date of Patent: March 5, 2013Assignee: Alcatel LucentInventors: Dennis Bijwaard, Harold Teunissen

Publication number: 20120257530Abstract: This document describes a method for wireless communication in large-scale monitoring and actuation applications. Typically, these networks must be designed to use efficiently available bandwidth in the wireless communication channel and to be able to deal with high node densities. The method mitigates the effects of co-channel interference, while allowing spatially distributed simultaneous transmissions.Type: ApplicationFiled: November 1, 2010Publication date: October 11, 2012Applicant: AMBIENT HOLDING B.V.Inventors: Dennis Bijwaard, Paul Havinga, Lodewijk Van Hoesel

Publication number: 20030026208Abstract: A telecommunications network includes a plurality of user nodes, a relay node, and controller means. The controller means is operative to allocate resources so as to control levels of traffic transmitted form/to the user nodes via the relay node. Specifically, the controller means is operative to allocate a data transmission rate for traffic from user nodes via the relay node to user nodes which is twice that for traffic via the relay node in from or out of the network.Type: ApplicationFiled: July 31, 2001Publication date: February 6, 2003Inventors: Dennis Bijwaard, B.F.
