Abstract: Apparatus and method for low density parity check code decoding in a first processing device, wherein the method includes receiving a first bit-word of a first length related to a log-likelihood ratio of a bit of a signal; obtaining a second bit-word of a second length that is shorter than the first length, wherein obtaining the second bit-word comprises applying a correction to the first bit-word; and determining a message depending on a set of second bit-words, wherein the set of second bit-words includes the second bit-word.

Abstract: Various example embodiments for supporting forward error correction (FEC) in a communication system are presented. Various example embodiments for supporting FEC in a communication system may include selection of a FEC setting (e.g., an amount of puncturing and/or shortening of a FEC code, a FEC code, or the like) for a communication channel from a transmitter to a receiver based on channel characteristic information of the communication channel from the transmitter to the receiver (e.g., transfer function information, channel loss information, noise characteristic information, error information (e.g., bit error rate, error modeling, or the like), or the like). Various example embodiments for supporting FEC in a communication system, based on selection of a FEC setting for a communication channel based on channel characteristic information of the communication channel, may be applied within various types of communication systems, including various types of wired and/or wireless communication systems.

Abstract: Systems for transmitting information from terminal systems (1) via access multiplexers (3) comprising virtual forwarder systems (5) to networks are made less complex by inserting at the terminal systems (1) virtual forwarder internet protocol addresses (35,64,66) into destination fields of internet protocol headers for heading the information and by inserting destination internet protocol addresses (36,37,38,65,67) into routing fields of the internet protocol headers. Both the terminal systems (1) and the access multiplexers (3) should be made capable of dealing with internet protocol headers of the internet protocol version-4 or the internet protocol version-6 or higher, which comprise a destination field and a routing field.

Abstract: Access nodes (1) for giving client devices (2,3) access to internet networks (5) comprise detectors (11) for detecting request messages in client information defining requests for receiving media contents and are provided with processors (12) for processing detections of the request messages for gathering statistical information about the media contents. The statistical information comprises viewing figures per media content. Further request messages in the client information define further requests for finishing receptions of the media contents for gathering further statistical information. The further statistical information comprises timing figures per media content. Data messages define client data with respect to the media contents for gathering yet further statistical information. The yet further statistical information comprises appreciation figures and/or yet further viewing figures per media content.

Abstract: 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’.

Abstract: A single ended line testing method for qualifying an electrically conducting line, including the steps of sending a plurality of randomized excitation signals from a first end of the line towards a second end of the line, subsequently taking measurements, at the first end of the line, of each reflection of the plurality of randomized excitation signals, and then inversely randomizing the measurements. Line qualification is determined based on an average of the inversely randomized measurements.

Abstract: Systems comprising aggregation equipment (1) and remote equipment (2-3) for exchanging messages between a subscriber unit (4,5,6,7,8,9) of the subscriber equipment (4-9) and the aggregation equipment (1) via a remote unit (2,3) of the remote equipment (2-3) are provided with translation equipment (12) for translating at least one virtual local area network identifier in at least one of the messages. As a result, it is no longer necessary to configure the remote equipment (2-3) to distribute the available virtual local area network identifiers among the remote equipment (2-3).

Abstract: 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.

Abstract: A packet based access multiplexer (DSLAM2) comprising an Ethernet switch (E-SWITCH2) and a single network processor (NP2) adapted to process at least part of incoming packets. The single network processor (NP2) is parallel coupled to the Ethernet switch (E-SWITCH2) in an architecture suited to process part of the packets, or alternatively is cascade coupled to the Ethernet switch in an architecture suited to process all packets.

Abstract: The present invention relates to a Single ended line testing method for qualifying an electrically conducting line. This method comprises the steps of sending a plurality of excitation signals from a first end of said line towards a second end of said line and before the sending of this plurality of excitation signals, randomising each excitation signal of the plurality of excitation signals. Subsequently, measurements are performed, at the first end of the line, of each reflection of the plurality of excitation signals sent towards the second end of the line. Then an inverse randomisation on each of the measurements of reflections is performed which is succeeded by determining an average of all the measurements of reflections of the excitation signals. Finally, from the average a qualification of the electrically conducting line is determined.
