Patent ID: 7345995

Claim:
A circuit arrangement for data stream distribution, the circuit arrangement comprising: a distributor device having a matrix switching unit, a first temporary buffer unit in communication with the matrix switching unit, and a second temporary buffer unit in communication with the matrix switching unit; a first data stream connection unit in communication with the first temporary buffer unit, the first data stream connection unit being configured to receive a data stream having a data stream cell, the data stream cell running in an opposing data stream direction and including a back pressure determination field and a back pressure bit vector field; a second data stream connection unit in communication with said respective second temporary buffer unit for receiving a data stream; a first access unit for providing communication between the first data stream connection unit and the respective first temporary buffer units, said first access unit being configured to buffer data; and a second access unit for providing communication between the second data stream connection unit and the respective second temporary buffer unit, said second access unit being configured to buffer data.
