摘要： The present invention relates to a switching system with a plurality of switching means (FM,SM) which are connected to a communication network (CM).
Each of said plurality of switching means operates independently of each other and has call processing means for executing a call processing in accordance with information from an associated subscriber line or trunk line.
Said communication network includes transmission means for transmitting information to be received/transmitted through an associated subscriber line or trunk line in the form of fixed length packets each having a header added thereto, said header containing information about a destination of said information.

摘要： Method and system for adapting access to a packet switching network including a dynamic bandwidth adjustment mechanism which continuously monitors the mean bit rate of the signal source and the loss probability of the connection. These values are filtered to remove noise and then used to test whether the values fall within a pre-defined acceptable adaptation region in the mean bit rate, loss probability plane. Values falling outside of this region trigger bandwidth adaptation procedures which, in turn, result in acquiring a new connection bandwidth, and determining new parameters for the adaptation mechanism. Furthermore, the mechanism controls the number of connections that can be adapted by a single processor, given its processing capability. It ensures fairness between the connections in the sense that it prevents a single connection to use, on the average, a unconsiderate portion of the processor capacity.

摘要： A method is described for network optimization based on a multirate, circuit-switched analysis. Network loss probabilities are determined as a solution of a set of fixed point equations and the sensitivity of network performance, as a function of offered load and loss probabilities, is determined as a solution to a set of linear equations. Because the numerical complexity of solving both the fixed point equations and the sensitivity equations is of an order which renders an exact solution computationally intractable, an asymptotic approximation is applied which yields a solution to the network loss probabilities and network sensitivities. A global optimization procedure is then applied using an iterative, steepest ascent optimization procedure to yield a set of virtual path routings and capacity allocations.

摘要： A cell buffer is provided for storage of cells for each quality class. A counter is provided for each cell buffer. A threshold value which regulates the respective readout interval is set for each quality class. The count of the counter for each quality class is increased by 1 for each time slot. When the count for a certain quality class reaches the threshold value, if a cell is stored in the cell buffer for that quality class, that cell is read out and output, and, at the same time, the count is decreased by the threshold value. When the count for a certain quality class reaches the threshold value, if a cell is not stored in the cell buffer for that quality class, the count is left unchanged.

摘要： A multimedia packet communication system, wherein connections can be selectively used automatically and dynamically in accordance with qualities required by an application, in which a plurality of communications of different required qualities are involved, to set quality classes, is disclosed. The multimedia packet communication system comprises a network layer including mapping means (204) for mapping a plurality of different required qualities from a layer protocol (201,202,203) of a higher layer than the network layer into corresponding connection types. The network layer further includes a driver (205) for setting the thus mapped connections to individual packets.

摘要： An improved access control system for a common or global data storage supporting virtual output queues dedicated to each of the output lines of the storage is described for data of different priorities. The improvement consisting in having thresholds for each priority class with respect to the global occupation level of the storage and to the occupation level of each virtual queue. The new access control system enables a contention control. It further includes the generation of a backpressure signal for the data transmitting input as to indicate the success of the transmission. This signal can be reduced to a single bit irrespective of the number of thresholds and priority classes.

摘要： Die ATM-Kommunikationseinrichtung (KE) dient zum Weiterleiten von im Zuge virtueller Verbindungen über zumindest eine Zubringerleitung (E1,...,En) zugeführten Nachrichtenzellen an eine für die jeweilige virtuelle Verbindung in Frage kommender Abnehmerleitungsanordnung (A1,...,An). Dabei werden für die jeweilige virtuelle Verbindung im Zuge des Verbindungsaufbaus charakteristische Parameter sowie eine von zumindest zwei unterschiedlichen Prioritäten festgelegt. Der jeweiligen Abnehmerleitungsanordnung ist eine Behandlungseinrichtung (BHE) zugeordnet, welche einen zentralen Zellen-Speicher (CM) aufweist, in dem verbindungsindividuelle Zellen-Warteschlangen für die Speicherung von Nachrichtenzellen eingerichtet sind. Mit dem Zellen-Speicher ist eine Steuereinrichtung (STE) verbunden, in welcher eine Zuordnungstabelle (LUT) geführt ist. Durch diese wird den in den Nachrichtenzellen geführten Verbindungsinformationen (VPI/VCI) eine Warteschlangen-Kennung sowie eine Prioritäts-Kennung zugeordnet. Nach Maßgabe der einzelnen Prioritäts-Kennungen werden die zugehörigen Warteschlangen-Kennungen in eine der jeweiligen Priorität zugeordnete Referenz-Warteschlange (Q1, Q2) eingefügt. Diese Referenz-Warteschlangen werden mit unterschiedlichen Prioritäten abgearbeitet, wobei die dadurch bereitgestellten Warteschlangen-Kennungen nacheinander dem Zellen-Speicher (CM) für eine Abgabe von gespeicherten Nachrichtenzellen zugeführt sind.
