ACTA has been proposed for high speed multimedia network. It is a simple multi-channel network protocol suitable for photonic implementation. It adopts slotted cycle to transmit packets and the cycle length is dynamically adjusted according to the network load. We study the performance of the ACTA protocol both for slngle-channel and multi-channel integrated services operations. Through the simulations, we have shown that the overhead of channel tuning is quite small. We also study the priority mechanism of ACTA, and analyze the relation between the node transmission quota and bandwidth allocation. In addition, we.present a slot reuse scheme which requires only one additional access control bit, and demonstrate great improvemeat in network utilization. The simulation results show that ACTA network is a very promising candidate for the future high speed multimedia networks.
