Problems solved by technology

[0019] The main disadvantage of the circuit structure based on the prior art data stream distribution method is the presence of long information channels which prolong the data stream exchange time
[0020] Another disadvantage of prior art stream allocation methods and devices is that conventional conflict resolution methods limit the total amount of streams that can be transmitted

Embodiment Construction

[0062] FIG. 1 shows the circuit structure of the data stream allocation according to the contention resolution method of the present invention.

[0063] In the circuit configuration of data stream distribution shown in FIG. 1, data streams are applied to first data stream connection units 104a-104n and second data stream connection units 105a-105m. The circuit structure of the present invention and the inventive method allow bi-directional transfer of data streams, so that the first data stream connection units 104a-104n and the second data stream connection units 105a-105m serve as circuit input and output connections.

[0064] By way of example, Figure 1 shows four first data stream connection units 104a-104n and four second data stream connection units 105a-105m. However, it should be pointed out that two or more first data flow connection units can be connected with two or more second data flow connection units, i is the order subscript, n is the total number of first data...

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.

Description

technical field [0001] The present invention relates to the circuit structure and method of data flow distribution, in particular to the circuit structure of data flow distribution with conflict resolution method. Background technique [0002] Usually, the circuit structure of data flow distribution is designed according to the principle of "cross-track distribution". In this context, data streams acting on one or more input connections are sent to one or more output connections. [0003] In addition to this unidirectional method, bidirectional methods are known which allow cross-track distributor device connections to function as inputs and outputs. In known protocols there are data streams—in particular bit data streams—to be transmitted, eg the known Ethernet V2 / IEEE 802.3 protocol. Conflicts arise especially in the case of bidirectional data streams passing from one or more inputs / outputs to one or more inputs / outputs, because elements of a data stream transfer prevent...
