A queue management system for selectively transmitting cells received from a plurality of sources, comprises: a multiplexer for multiplexing the cells from the plurality of sources into one output line; a cell pool for storing the cells received from the multiplexer; an idle-address FIFO for storing addresses of empty sectors of the cell pool; a sequencer, having a plurality of modules therein, each module for determining the cells' sequence of transmission, for storing information including a cell's priority field and its corresponding address in the cell pool, comparing the stored information with information of a new entry cell, and queuing the information on the basis of the priority field, wherein the priority field is composed of a deadline time and an eligible time, the deadline time being defined as a maximum allowable delay bound at a node and the eligible time, referring to a delay bound in which a cell is supposed to be transmitted from the node; and a write controller and a read controller for generating signals for accessing to the multiplexer, the cell pool and the sequencer.
