Abstract: A communications system and method enables delivery of packets over network boundaries while preserving the QoS bits configuration. The communications system includes at least one sending site configured to send the packet. The packet may have a first set of bits in a first bit-set location that indicates an intended packet forwarding priority of the packet. A data network is included that has a traffic class identification. The data network associates the packet forwarding priority with the traffic class identification and writes a second set of bits into the first bit-set location of the packet based on the traffic class identification. The second set of bits indicates a delivery priority that corresponds to the packet forwarding priority. The packet is forwarded based on at least one of the packet forwarding priority and the delivery priority, wherein the delivery priority is based on the data traffic class identification.

Abstract: The present invention relates to transmitting data units of a radio protocol layer, wherein one logical channel identifier is added to one or more data units belonging to one logical channel. Because only one logical channel identifier is added to the data units belonging to one logical channel in constructing a MAC-e PDU, overheads of the MAC-e PDU are reduced. Such reduction of the PDU overheads increases data throughput, which is advantageous for a high-speed data communication system, such as the HSUPA.

Abstract: A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and determining whether one or more samples included in the flow should be suppressed. The method also includes suppressing a selected one or more of the samples. The method also includes retransmitting certain samples when a given sample has stopped changing, in comparison to a previously received sample, for a configured time interval.

Abstract: A first block of packets is sent through a network at a first throughput rate. The first block of packets has a differential treatment field set to a first value. A second block of packets is sent through the network at a second throughput rate. The second block of packets has the differential treatment field set to a second value. A first report indicating that the reception of the first block of packets satisfies a criteria is received. A second report indicating that the reception of the second block of packets satisfies the criteria is received. A treatment field value for the differential treatment field is selected based on the first report and the second report. A packet with the differential treatment field set to the treatment field value is sent to the network.

Abstract: The invention provides a method for operating an apparatus capable of Bluetooth and Wireless Local Area Network (WLAN)/WiMAX communications. In one embodiment, the apparatus comprises a Bluetooth module, and a WLAN/WiMAX unit comprising a packet traffic arbitration (PTA) module, and a WLAN/WiMAX module. The Bluetooth module sends a request for Bluetooth signal transceiving to be performed in a Bluetooth time slot to the WLAN/WiMAX unit, wherein the request comprises a length information about length of a transceiving time period for Bluetooth signal transceiving. The Bluetooth module then performs an Bluetooth signal transceiving during the transceiving time period of the Bluetooth time slot after the WLAN/WiMAX unit grants the request. The WLAN/WiMAX unit then performs an WLAN/WiMAX signal transceiving during a residual time period of the Bluetooth time slot in response to the length information.

Abstract: The present invention relates to a method for data-flow quality control in a Digital Subscriber Line communications system comprising a transmitter, a receiver, and a Digital Subscriber Line intercoupling the transmitter and the receiver. The transmitter sends a data-flow to the receiver, where the data-flow is modulated onto data-carriers according to a bit allocation indicative for the number of bits to be modulated on each data-carrier. The method comprises the steps of the receiver measuring the data-flow quality and subsequently the receiver instructs the transmitter to decrease the bit allocation with a same amount for a plurality of data-carriers in case the data-flow quality is unsatisfactorily low. Then the transmitter decreases the bit allocation accordingly.

Abstract: An apparatus includes ports to transmit and receive packets, each packet being associated with one of a plurality of sessions, and a packet buffer to store the packets. A classifier identifies packets that include data representing a transmit window size for one of the sessions. A processor determines whether to reduce the transmit window size for the one of the sessions by comparing a size of the packet buffer to a sum of (i) the transmit window size for the one of the sessions and (ii) transmit window sizes for others of the sessions. The processor modifies the data representing the transmit window size for the one of the sessions to reduce the transmit window size for the one of the sessions before one or more of the ports transmits the packets comprising the data representing the transmit window size for the one of the sessions.

Abstract: A technique for examining the relationships of autonomous systems (ASes) participating in an Internet Exchange Point (IXP) utilizes packet tracing servers proximate the IXPs. Where such packet tracing servers cannot be found in the participating ASes, the methodology identifies additional vantage points by looking at a list of ASes that are one hop away from the ASes at the IXP. The choice of one-hop away ASes is made judiciously by picking ones that have better connectivity, based on past-data. Plural-hop ASes may also be used where necessary.
