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 determination whether to establish a new connection that will supply new variable bit rate data packets to be transmitted in a shared system for transmitting variable bit rate data packets is made by determining, for the new connection, a value of a moment generating function defined based on the number of possible data packet sizes for the new connection, (Ri, Pi) pairs representing possible new connection data packet sizes, Ri, with corresponding assigned probabilities, Pi, and theta is an arbitrary positive real number. A determination is then made whether any value of theta exists that satisfies the Chernoff bound for all established connections and the new connection, given a length of a buffer for storing data packets supplied to the shared system for transmitting variable bit rate data packets, and a predefined packet loss rate that can be tolerated in the shared system for transmitting variable bit rate data packets. If a value of theta exists that satisfies the Chernoff bound, then the new connection is established, else it is rejected. In another aspect, a maximum number of connections in the shared system is determined, given a transmission rate of the shared system.

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.

Abstract: A digital switch intended for use in a node in a circuit switched telecommunication network with a distributed switching function includes a switch memory, and a time slot counter, which is connectable to the switch memory and arranged to point out an address in the switch memory for cyclical writing of incoming data into the switch on this address. A control memory is arranged for controlling the sequence order for read out of data from the switch memory. The switch memory is connectable via an adapting device to a transmission medium, which is common to a number of nodes in the network. The time slot counter is connected via the adapting device to receive frame synchronization from the common transmission medium. The control memory is arranged for selecting time slots from the common transmission medium and generating read address to the switch memory. The control memory and the switch memory are realized with fewer memory cells than admitted by the address space.

Abstract: A system and a method are described herein which provide for congestion handling in a packet switched network domain. In case of congestion overload is measured by a core node, the data packets in proportion to the overload are marked and the signaled overload is stored. At least one egress node receives marked and not marked packets, decodes and counts the overload from the marked packets in a counting interval. Congestion report messages are sent to ingress nodes where flows are terminated.
