    摘要: A method is described for controlling the switching of data packets through a network element. he method comprises the steps of receiving first data packets at an input module and storing at least part of the received first data packets into an input queue of the input module, calculating from the status of the input queue a first quantity of the first data packets and requesting the first quantity of data packets to be switched from the input module to an output module, granting a first allowed quantity being all or part of the first requested quantity of data packets to be switched. The method further includes the steps of, before the step of granting, receiving second data packets at the input module and storing at least part of the received second data packets into the input queue, calculating from the value of the first requested quantity and from the status of the input queue a second quantity of the second data packets and requesting the second quantity of data packets to be switched from the input module to the output module.

    摘要: It is disclosed a method for transmitting a data traffic in a communication network. The method comprises: distributing the data traffic onto a subset of active virtual lanes among a set of available virtual lanes; marking each available virtual lane by superimposing a respective multiframe upon the data of the virtual lane so as to distinguish the active virtual lanes from the other available virtual lanes, and, on the basis of the marking, mapping the active virtual lanes to data units suitable for transmitting the data traffic through the communication network.

    摘要: Method for performing a failure analysis of a communication network comprising links and nodes supporting transmission of service demands. The method comprises: selecting a failure combination affecting the links and/or the nodes; determining one or more broken service demands and one or more broken links affected by the failure combination; computing a respective restoration path for each broken service demand by excluding the broken links; determining whether at least two broken service demands have respective restoration paths that share a network resource over a conflicting link; and, in the affirmative: associating the shared network resource to one of the at least two service demands; removing, from the broken service demands, this service demand and the service demands whose restoration paths do not share any network resource; adding the conflicting link to the broken links; and repeating the above operations until a termination condition is fulfilled.

    摘要: A method is described for switching digital signals. The method includes the step of generating multiple input flows from multiple inputs, the number of the multiple input flows being higher than the number of the multiple inputs; the step of arranging the multiple input flows into first multiple groups of flows taking into account the switching capacity of at least two fabric switches, the number of flows switched by each of the at least two fabric switches being smaller than the number of the multiple input flows; the step of duplicating the first multiple groups of flows into at least one corresponding copy; the step of arranging the first multiple groups and the at least one corresponding copy into second multiple groups of flows; the step of switching flows of the second multiple groups into the at least two fabric switches; and the step of selecting multiple output flows from at least part of the switched flows of the second multiple groups.

    摘要: It is disclosed a method for updating a cumulative residence time of a synchronization packet received at a node of a packet-switched communication network. The cumulative residence time is equal to a cumulative sum of residence times of the packet at nodes interposed between a further node which has generated the packet and the node. The node comprises an ingress circuit and an egress circuit. The method comprises: receiving the packet at the egress circuit from the ingress circuit; at a timestamp generator of the egress circuit, generating a timestamp; at the egress circuit, calculating a virtual timestamp based on the timestamp and on an estimated variable delay that will be undergone by the packet due to buffering in a buffer located downstream the timestamp generator; and, at the egress circuit, using the virtual timestamp for updating the cumulative residence time, before transmitting the packet to a still further node.
