Abstract: The invention relates to a method for establishing a distribution compartment in a packet-switched network. A classification of the network nodes is carried out according to output nodes of the network during which the class of a node is determined according to the minimum number of hops between the network nodes and the output nodes. Based on the classification, distribution compartments for flows can be established as to provide a freedom from loops and to enable a flexible reaction to malfunctions.

Abstract: The invention relates to a circuit arrangement for data stream distribution with conflict resolution, whereby data streams are transmitted bi-directionally, such that first data stream connection units (104a-104n) and second data stream connection units (105a-105m) serve as both input and output connections. A distribution unit (100), essentially comprises a matrix switching unit (101), first intermediate buffer units (106a-106n) and second intermediate buffer units (107a-107m). Information is firstly evaluated in the cell head, which, together with information on the availability of intermediate buffer units, determine when a present data stream cell may be transmitted to a relevant output connection unit.

Abstract: A method for operating a switching system for data packets includes providing a switching system having inputs and outputs, temporarily storing data packets at an input of the switching system where, when each data packet arrives, merely sending a message to an output of the switching system at the input and placing the message into a queue at the output. The method combines advantages of temporary storage at the input with the advantages of temporary storage at the output, without having to accept the disadvantages of one of such systems.

Abstract: A method for switching a plurality of packet-oriented signals and an apparatus for performing the method includes supplying a signal to port units, each having ports, at one port, some ports, or all ports. A signal is connected from one port to another port of another unit by a central switching unit. Signal transmission therebetween is performed by transmission of data blocks. Each port unit ascertains the address information item for each packet supplied and uses the item to determine the appropriate receiving port unit. Each port unit stores the data packet in a buffer memory, compiles availability information and transmits it to the switching unit, which evaluates availability and ascertains further transmission without blocking occurring. The switching unit connects the necessary paths between the transmitting and receiving port units and transmits the packets/cells through the paths.
