atm switch in the cell loss rate in order to improve the reverse pressure signal of the input buffer control device and buffer size decision logic algorithm

摘要

this invention is a method of input buffer input buffer type switch in the system is input into the input buffer and the input buffer in order to control of a controller in the switching element, in particular in the routing table uce21uc73cub85c is reverse pressure signal transmission and the input buffer will be stored in the battery information of the switching system, the input of the input buffer, the size of the active set method in.;the old way, the size of the input buffer temporarily assigned to the area, which has a priority number is equivalent to the input drive is a multi phase traffic characteristics, the other the uc21cuc704uc758 input buffer in place of others may, a priority class of the buffer is not enough, the loss of the cell can be increased.;according to the invention the input buffer controller of the control system of the distribution of the input unit according to the size of the buffer allocated to the old way of cell loss priority zone.
