Abstract: The bandwidth utilization and transmission efficiency associated with the point-to-point transportation of internet protocol (IP) data packets in a network environment is improved by employing asynchronous transfer mode (ATM) adaption layer two (AAL2) minicells as a bearer. Bandwidth utilization and transmission efficiency may be further enhanced by mapping one or more data fields from the header portion of the IP data packets into one or more look-up tables and then transporting the look-up table addresses in the AAL2 minicell headers rather than the data associated with the one or more data fields in the IP data packet headers.

Abstract: Transportation of low bit rate, circuit emulation data over an asynchronous transfer mode (ATM) connection is improved by packetizing the circuit emulation data into short packets in accordance with a packetization clock. The packetization clock is derived as a function of the ATM cell shaping clock. The short packets are then multiplexed together into a single ATM connection and transported to a receiving unit in accordance with an ATM cell shaping clock. The circuit emulation data is then extracted at the receiving unit and forwarded to the corresponding circuit emulation connection at the appropriate service rate, which is recovered based on ATM connection characteristics.

Abstract: The present invention deals with the problem with packet based services consuming considerable bandwidth over links with shortage of bandwidth. The object of the present invention is to reduce the amount of information when transferring a signalling message and thus save bandwidth. After receiving a signalling message in a first node the signalling message is identified. The signalling message is replaced by an indicator, under usage of information from the identification, which indicator is transferred to a second node. Th e second node restores the signalling message using the indicator.

Abstract: In a telecommunication system that generates more than one type of communication data stream, in which each data stream exhibits a distinctive data transfer format, bandwidth utilization is improved by first reformatting the different data transfer formats so that all of the data is compatible with a common data transfer protocol, for example, the Asynchronous Transfer Mode (ATM) protocol. The communication data and the corresponding control data, required to maintain communication data alignment, are multiplexed into a single data stream which is then transmitted over a common telecommunication channel to a receiving station.

Abstract: A method for discarding data within an IP-network communications link (10) i n a manner that optimizes the quality of speech data contained in the IP-netwo rk communications link (10). Initially, the IP-network communications link (10) is monitored to determine the occurrence of an overload condition. At least a portion of a plurality of data packets (30) within the IP-network communications link (10) are selected in response to detection of the overlo ad condition. The selected portions are discarded from the IP-network communications link (10), and the remainder of the packets (30) transmitted on the link (10).

Abstract: The soft state of a header compression scheme in a communication system carrying packet traffic including a real time communication signal can be updated (63) during periods of communication signal inactivity (62), during which there is no need to transmit the communication signal. The header compression soft state can also be updated by stealing bits (83, 84) from th e communication signal to carry the header update information (73). If the communication signal includes source encoded data, the header compression so ft state can be updated selectively (126) based on the bit rate (122, 124) of a codec that produced the source encoded data.

Abstract: Data packets are transmitted in forward and backward directions via a multiplexed communications medium, wherein each of the data packets is associated with a corresponding one of a plurality of connections. Transmission is performed by, for each connection, assigning a forward delay limit and a corresponding backward delay limit, wherein the sum of the forward and backward delay limits is equal to a round-trip delay bound for the connection. The assigned forward delay limits are used to determine the order in which the data packets supplied by the plurality of connections will be transmitted in the forward direction. Similarly, the assigned backward delay limits are used to determine the order in which the data packets supplied by the plurality of connections will be transmitted in the backward direction. One embodiment accomplishes the forward and backward delay limit assignments by maintaining forward and backward lists of connection identifiers sorted in, for example, ascending order based on time of connection establishment in the forward direction, and in descending order based on time of connection establishment in the backward direction. In another embodiment, transmission order is determined by sorting arriving data packets at the time of their corresponding connection identifiers, wherein the forward and backward sorting rules are selected so that a sum of a forward transmission delay limit and a backward transmission delay limit is less than or equal to a round-trip delay bound for each connection.
