Patent number: 9426062Abstract: The invention relates to a method of fault monitoring in a fault monitoring entity of a network node of a network having at least a first connection-oriented network layer, having first protection measures associated therewith, and a second connection-oriented network layer, having second protection measures associated therewith. In a first step the service condition status of the first network layer is monitored using the first protection measures. In a second step the second network layer protection measures are determined for onward transmission within the second network layer depending on the service condition status of the first network layer. Since the network node is aware of the monitored status condition of both the first and second layers the protection mechanisms for the first network layer and the second network layer can be co-ordinated and the second network layer protection measure for onward transmission may be determined for optimum network fault protection operation.Type: GrantFiled: January 15, 2010Date of Patent: August 23, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Raoul Fiorone, Riccardo Martinotti, Andrea Corti

Patent number: 9203732Abstract: A connection-oriented network (5) has a plurality of connections terminated at a first node (N6). A recovery group (A) is configured at the first node (N6) comprising at least two of the plurality of connections (LSP1-6, LSP2-6, LSP3-6, LSP4-6). Fault detection is performed over each of the connections in the recovery group (A) and the node determines if at least one recovery group fault condition is met, based on the results of the fault detections performed over the connections in the recovery-group (A). When the at least one recovery group fault condition is met, the node causes traffic on the plurality of connections in the recovery group (A) to be transferred to backup paths. When the at least one recovery group fault condition is not met, and a fault has been detected on a connection in the recovery group (A), the node causes traffic to be transferred from that connection to a backup path.Type: GrantFiled: October 1, 2009Date of Patent: December 1, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Raoul Fiorone, Andrea Corti, Riccardo Martinotti

Patent number: 9112629Abstract: Configuring a node (410) of a synchronization network involves identifying (10) possible alternative time synchronization trails arranged to carry time synchronization information for time synchronization at the node, and possible alternative frequency trails, arranged to carry frequency synchronization information for frequency synchronization at the node. Using information about the sources (20), a comparison of the trails (30) is biased to increase a likelihood of choosing time synchronization and frequency trails which share the same source, over a likelihood of choosing trails with different sources. This can help avoid divergence and consequent bit errors arising from phase errors, resulting from trails having different sources. It can encompass for example changing both to a new common source, or changing one or both trails while still using the old common source.Type: GrantFiled: January 18, 2010Date of Patent: August 18, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Stefano Ruffini, Raoul Fiorone, Sergio Lanzone, Orazio Toscano

Patent number: 8750111Abstract: A method and a transport scheme for packets of traffic over a logical link made up of the aggregation of several physical links (16) connecting a transmitting side to a receiving side in which flows of incoming packets are sent to a scheduler/shaper (12) which selects therefrom packets for creating a global flow of packets falling within the bandwidth offered by the logical link on the basis of the bandwidth capability offered by the logical link. A distributor (13) distributes the global flow over the plurality of physical links (16) making up the logical link, oversees the physical links and sends to the scheduler/shaper signalling of a bandwidth decrease caused by failures of one or more physical links. The scheduler/shaper (12) is arranged to allow automatically for the logical link bandwidth variations while selecting the packets from the various incoming queues depending on the associated service class so as to cause the global flow to fall within the aggregated logical link bandwidth.Type: GrantFiled: November 23, 2006Date of Patent: June 10, 2014Assignee: Ericsson ABInventors: Riccardo Martinotti, Raoul Fiorone, Andrea Corti

Patent number: 8730815Abstract: A node (110) for an MPLS telecommunications network has interfaces (100) for OAM information exchange relating to a path for data traffic, between first and second other nodes each operating according to different OAM state machines for OAM information exchange. An OAM state machine mapper (120) maps the states of either of the different OAM state machines of the first and second other nodes into states recognized by the other of the different OAM state machines. OAM information exchange is according to either the first or the second OAM state machine and according to states mapped from the other of the OAM state machines, to support the path for data traffic through the node. By such mapping of the different states OAM information can be exchanged across corresponding boundaries and so paths no longer need to be terminated at the boundary to enable end to end operations.Type: GrantFiled: April 27, 2011Date of Patent: May 20, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Antonella Sanguineti, Riccardo Martinotti, Raoul Fiorone
