Conflict resolution in data stream distribution

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 ( 104 a- 104 n) and second data stream connection units ( 105 a- 105 m) serve as both input and output connections. A distribution unit ( 100 ), essentially comprises a matrix switching unit ( 101 ), first intermediate buffer units ( 106 a- 106 n) and second intermediate buffer units ( 107 a- 107 m). 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.
