QMNF: QoS Multicast Routing Protocol Using N-Hop Dominating Flooding Approach on Programmable Network

QMNF is a QoS-aware multicast routing protocol using N-hop dominating flooding and built upon a layered routing architecture. 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-probing packets, and employs a two-pass resource reservation scheme to avoid unnecessary resource reservation. The QMNF is QoSaware, loop-free, flexible and scalable, and improves network resource utilization. In our simulation, the performance of QMNF is compared with that of traditional flooding protocol with the shortest path resources reservation, a traditional flooding protocol with the widest path resources reservation, PIM and QMBF. The simulation results confirm that QMNF has a high success rate and good resource utilization, and it can distribute traffic in a network evenly. key words: N-hop flooding, programmable network, QoS multicast routing, QMNF
