METHOD FOR CONTROLLING OVERLOADS IN ATM COMMUNICATIONS SYSTEMS
Cells are transmitted with possible bit rates and overload information (NÜ(NI/CI)) via an existing virtual connection, using two ATM-communications terminals (KE1/KE2) that are connected to an ATM communications system (ATM-KS). In the event that an overload is identified in the ATM communications system (ATM-KS) for a virtual connection in one direction of transmission (ÜR1), the overload information (NÜ(NISx,CISx)) is inserted into the cell stream (ZS(ÜR2)) flowing in the opposite direction of transmission (ÜR2). The insertion of the overload information (NÜ(NISx,CISx)) can be permanent as well as temporary. The invention hereby provides a significantly more rapid means of controlling overloads in ATM communications systems.
