USER PARAMETER CONTROL IN THE ATM VIRTUAL CONNECTION AND THE

摘要

a cell input processor for extracting fields for control by temporarily inputting an input ATM cell in one cell unit time and sparing any time for a control process; an imaginary connected discrimination translating unit for converting an imaginary connected discriminator into a specific address of a memory in order to find out the input cell to be inputted the input cell processor; a parameter storage memory for inputting a cell/octet timing signal and storing a traffic parameter to be used for controlling the specific address; a determination logic circuit for comparing the stored cell parameter with a real parameter, and outputting a determined signal according to the result of the comparison; and a cell output processing unit for outputting a cell packet and tagging of the cell input processing unit under use of the resulted signal from the determination logic circuit and the priority of cell damage.
