Usable Variable Control / Adaptive Cell Interval Adjustment Method of Network Variable Control (UPC / NPC)

摘要

The present invention relates to an adaptive cell interval adjustment method of UPC / NPC using credits for preventing congestion in a network due to a variation of cell transmission delay in ATM by reducing the delay by improving the RAT and RDT algorithms (UPC / NPC) judgment result by interworking with UPC / NPC, which monitors whether the user traffic conforms to the negotiated traffic parameter, For use, the theoretical cell arrival time is TAT (i); If the actual cell arrival time is t_a(i) if the allowed cell delay variance is ,;And the small cell gap of the output cell is allowed when the credit is large and the cell gap of the output cell is ensured to be close to the maximum gap as the credit is small.
