ABSTRACT:
For route searching in a multi-stage ATM switching matrix network, the free transmission capacities of ATM links are individually stored with an occupation memory. For setting up new virtual connections, a required transmission capacity is reported. Based on the extent thereof, a route selection occurs only via ATM links having free transmission capacity that is momentarily adequate. Bit rate classes are formed for storing the free transmission capacity. The required transmission capacities are also classified therein. For a respective ATM link group that is connected to an ATM switching element at the output side and/or input side, link-associated storage locations are binarily identified in storage cells of the occupation memory provided per bit rate class when transmission capacity corresponding to the allocated bit rate class is still respectively freely available. Presence of coincidence in view of the binary identification established for the respective bit rate class is checked in the route searching.
