A CONTROLLER FOR DISTRIBUTING LOADS AMONG CALL PROCESSORS

摘要

A main processor (3) assigns originated-call processings to each of a plurality of call processors (2a ... 2n) in the sequence of call originations according to the first principle of this invention. A switching state controller (4) collects usage information about a plurality of buffers composing the switching network (1) in the ATM exchanger. The call processors (2a ... 2n) to which call processings are assigned perform the call processings based on the content of switching state controller (4). A main processor (3) assigns a call processing for an originated call to one of a plurality of call processors (2a ... 2n) by referring to the call processing assignment table memory (5) with the virtual channel identifier corresponding to an originated call according to the second principle of this invention. Thus, call processing loads are distributed among call processors (2a ... 2n).
