Patent number: 9276870Abstract: A packet switching node is coupled by links to other nodes of a network, and receives and assembles packets belonging to a specified packet flow, into bursts of packets with a burst control packet indicating a sequence of the burst in the flow. The node determines whether to distribute the flow across several links. If so, the bursts are then forwarded for switching to the output ports of the selected links. Distributing the flow over multiple links can enable more flexible and efficient filling of allocated bandwidth on links, as traffic increases. To reduce the risk of losing the order of packets the sequence of the bursts is indicated for use in reordering at intermediate nodes during transmission through the network.Type: GrantFiled: August 25, 2010Date of Patent: March 1, 2016Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Patrizia Testa, Angelo Germoni, Marco Listanti

Patent number: 9197438Abstract: A packet forwarding node of a transport network performs a first packet forwarding mode in which received packets are processed and forwarded on a per-packet basis. The forwarding node performs a second packet forwarding mode when the node identifies a group of consecutive packets. The group of packets are destined for the same destination node of the transport network. The second packet forwarding mode comprises determining a forwarding treatment for the group of packets and forwarding the group of packets with the determined treatment. The forwarding is performed without processing the headers of at least some of the packets in the group. The group of consecutive packets is identified by a control packet preceding the group or by inter-packet signalling which indicates that the packet before the inter-packet signalling and the packet after the inter-packet signalling are to be treated as part of the same group.Type: GrantFiled: December 18, 2009Date of Patent: November 24, 2015Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Patrizia Testa, Angelo Germoni, Marco Listanti, Roberto Sabella

Publication number: 20140198812Abstract: A communications network transport node comprising an optical add-drop multiplexer (OADM), comprising optical signal processing apparatus, electrical signal routing apparatus, and a packet switch. Each optical signal processing apparatus comprises an optical input, an optical output, optical-to-electrical (O-E) signal conversion apparatus arranged to receive input optical channel signals and to convert each into an input radio frequency (RF) modulated electrical channel signal, and electrical to optical (E-O) signal conversion apparatus arranged to receive output RF modulated electrical channel signals and to convert each into an output optical channel signal. The electrical signal routing apparatus determines which input RF modulated electrical channel signals are to be dropped, and routes these to the electrical drop outputs, and which are to be transmitted, and routes these to a selected E-O apparatus.Type: ApplicationFiled: June 3, 2011Publication date: July 17, 2014Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Bengt-Erik Olsson, Fabio Cavaliere, Patrizia Testa

Publication number: 20110176415Abstract: A method is proposed for controlling the admission of connections in a wireless communication system between a base station and a subscriber unit, in which the modulation and coding scheme of the uplink and downlink can be varied over time. The method comprises the steps of receiving a request for a connection and of admitting the connection and updating the available bandwidth, if the available bandwidth corresponding to the current AMC scheme is greater than the admission bandwidth of the connection. Moreover the method periodically evaluates if the current admission bandwidth can be changed for a plurality of active connections: if this is the case, and there is not enough bandwidth to allow the change, the method stops the admission of new connections, suspends at least one active connection of said plurality of active connections or changes the AMC scheme of such at least one active connection.Type: ApplicationFiled: August 29, 2008Publication date: July 21, 2011Inventors: Marina Settembre, Patrizia Testa
