METHOD OF INTELLIGENT CELL DISCARDING IN ATM SWITCHING SYSTEM

摘要

The present invention provides a VPI / VCI (Virtual Path Identifier) in a cell header when providing an ABT service.;The intelligent cell closure method in an asynchronous delivery switch that quickly eliminates the overload condition generated by using the / Virtual Channel Identifier value and efficiently uses the wasted bandwidth. A first step of checking whether it has been exceeded or if the current exchange is overloaded; A second step of determining whether a cell is in communication or an ongoing service is ABT according to the cell entry rate or an overload state of a current exchange; And the third step of tagging or discarding the corresponding cell if the ongoing service is not the ABT service and releasing the circuit connection or discarding the corresponding block if the ABT service is the ABT service. High effect can be expected to prevent and eliminate overload.
