METHOD AND DEVICE FOR MULTICASTING OF ATM CELL

摘要

PROBLEM TO BE SOLVED: To efficiently multicast ATM cells by using a less number of memories. SOLUTION: A first ATM cell pointer 62 related to a first port 18a and a second ATM cell pointer 76 related to a second port 18b have first ATM cells 14a. The pointer 62 indicates a first node 64 having a first address 66 and a node address pointer 68. A second node 70 having a second address 71 exists and the node address pointer 68 of the first node 64 indicates a second node 70. Each node forms a link list 72 of addresses and a first ATM cell 14a has a cell pointer 20. A multicasting system has a second ATM cell 14b and the cell pointer 20 of the first ATM cell 14a indicates the second ATM cell 14b. The first and second ATM cells 14a and 14b form a link list 14b. The multicasting system has a controller 250 and a write pointer 26.
