In this investigation, we propose a new multicast protocol, QoS multicasting routing protocol on N-hop dominating flooding (QMNF), based on a layered routing architecture of active network approach. In this architecture, QMNF invites the N-hop flooding component and the shortest path routing table from OSPF by open signaling interfaces, floods the path-finding messages in capsules and employs two-pass resource reservation scheme to avoid unnecessary resource reservation. In our simulation, we compare the performance of QMNF with a traditional flooding algorithm, an optimal flooding algorithm, PIM and QMBF. The simulation results confirm that QMNF has the high success rate, the better resource utilization and the traffic can be distributed evenly in a network
