Abstract
An internal routing tag ( ) is appended to a payload of a received ATM cell upon ingress of the ATM cell into a multi-stage ATM node ( ). The routing tag comprises routing information for routing the payload of the received ATM cell through plural stages ( ) of the multi-stage node. Preferably the routing information comprises a list of destination addresses, e.g., utopia address of physical units ( ) in the multi-stage ATM node. Use of the internal routing tag streamlines connection setup, reduces the number of internal control paths required, and obviates VPI/VCI conversion at the plural stages of the multi-stage node.
