USTRACT. The mutmg in ATM networks consists in assigning a path to the CoMCctio~ls dunands. For each new call the network must select a path that has s&cicnt baadwictth available to canbd (CAC) policy bas a stmq influence in the routing pdormancc.?he CAC propossd hr the cvaluatioll ofthe best routing option is the Enhanced Convolution Approach. supportthe L L c w d m. Every cell ofthis call will use the same route path. 'Iheodopted dl admission In the future broadband network an &d requirement arises. Indeed, somc scrviccs have a distributive nature, and thus reqrure of fittux ATM switches the capablltty to provide a multicast and broadcast filnctiOrdlQ. I In thls paper we propose an multicast implementation based on the adaptive routing with auticipated calculation. Three different cost measures for a point-to-multipoint c o w o n: bandwictth cost, carmtction establisment cost and "g cost can be cwsidmd. The application of the adaptative routing method based in preevaluated m u t q tables makes possible the reduction of bandwidth cost and CwLltCtioLl establishment cost individually. 1. INTRODUCTION. The routing in ATM networks consists in assigning a path, virtual channel (VC) or
