METHOD FOR REMOVING ATM CELLS FROM AN ATM COMMUNICATIONS DEVICE

摘要

A number of algorithms have been used in prior art for dealing with overload situations in ATM transmission systems. The PPD and LPD algorithms are examples of known methods. When the PPD method is used, the dynamic load to which the ATM network is subjected is still too great since not all of the ATM cells can be rejected. Those ATM cells which do not belong to a frame also pose a problem in the rejection process. The invention solves this problem by establishing rules which when applied, ensure that the PPD method is only used within very strict limits and that those ATM cells not belonging to a frame are not rejected.
