    摘要: A method to preserve the ordering of data packets of a same flow (P1-P4, P7, P8) passing either through a control plane (CP) or through a data plane (DP) of a telecommunication network element. The method comprises the step of, when the control plane starts processing the new flow, the control plane controls the data plane to latch any other packet belonging to this flow by sending a first control packet (C1) to said data plane. When the processing is completed, the control plane controls the data plane to release the latched packets by sending a second control packet (C3) to said data plane. The present method is particularly applicable to Ethernet frames, where it is also not allowed to reorder frames belonging to a same ‘Ethernet flow’.

    摘要: The present invention relates to a multicast traffic control unit (21) for use in a data communication system (1) operable to transmit multicast traffic, and adapted: to receive membership reports (41 to 45) from at least one station (11 to 13), whereby memberships of multicast groups are notified, to report at least one membership (41, 44) out of said memberships to a multicast router (31) of the data communication system. A multicast traffic control unit according to the invention is further adapted, before reporting the at least one membership to the multicast router: to estimate a total amount (X) of multicast traffic which the multicast router would supposedly forward towards the at least one station on account of the at least one membership, to select the at least one membership such that the so-estimated total amount does not exceed a configurable threshold (Xmax).

    摘要: Network units (1) for exchanging signals (20-70) comprising information (50) at layers (500) higher than internet protocol layers (300) comprise detector systems (2,3) arranged to detect fields of the information (50). To improve the detections of a status of priority, of fragmentation and/or of aggregation, the signal (20-70) is provided with further information (60) at further layers (600) higher than the layers (500) and the detector systems (2,3) are arranged to, in response to detections of the fields of the information (50), detect further fields of the further information (60). The further layers (600) comprise codec independent layers and yet further layers (700) higher than the further layers (600) comprises codec dependent layers. The layers (500) comprise real time protocol layers, the further layers (600) comprise generic real time protocol payload formats for transport abstractions and the yet further layers (700) comprise real time protocol payload formats for specific codec's. The further fields of the further information (60) comprise priority fields (611-d), fragmentation fields (611-b-c), aggregation fields (611-a), aggregation count fields (612) and aggregation header fields (613-618).

    摘要: An access node (1) that is preferably a Flow-Aware Ethernet DSLAM adapted to transmit Ethernet data frames between subscribers (2) and an aggregation network (3). The access node comprises a first memory (4) for storing classification rules and a second memory (6) for storing flow rules. These rules are applied by a classification agent (5) and by a service agent (7) to information extracted from incoming data frames in order to infer flow awareness information of outgoing frames corresponding to these incoming data frame. In this way, the subscriber access network evolves to a multi-service architecture by replacing ATM with Ethernet for cost reasons. The concept of “flow awareness” is applied to the present access node. With respect to known tunnel-based Ethernet DSLAMs, the present access node removes all dependency on correct encapsulation or labeling at the customer side and at the service provider side. By removing the need for tunnels, traffic may be inserted at any intermediate point, as may be required for multicast.
