Abstract
The invention relates to a distribution of load to peripheral adaptation units of a packet-based switching system, whereby the peripheral adaptation units serve as an interface between the packet-based switching center and a packet-based communications network. According to the invention, a load that accrues in the switching center is statically or dynamically distributed to the peripheral adaptation units by a load distributor. This enables the periphery adaptation units to be utilized whereby preventing wiring-related overloads and, in addition, being able to take different performance capacities of the peripheral adaptation units into account. When at least one additional switching center is provided upstream, a load budget concerning its use of the peripheral adaptation units can be transmitted thereto from the packet-based switching center. The load distribution is adapted in the event of hardware failures and signaling interferences.

18. A method for load distribution in a packet-based switch in which peripheral adaptation units are used as the interface between a packet-based communications network and applications of the switch, the method comprising:
-
performing communication and/or signaling tasks by the applications;
determining the individual workloads of the peripheral adaptation units; and
forming an assignment between the applications and the peripheral adaptation units depending on the determined workloads. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
