  1. QMBF：A QoS-aware Multicast Routing Protocol Zhi Li and Prasant Mohapatra CS UCDavis Network Lab IEEE ICC2002 ; Elsevier Science Computer Communications Journal

  2. Outline • Introduction • Problem define • QMBF • Simulation • Conclusion

  3. Introduction QoS-based multicast routing requirement: • Scalability to large groups • Support for dynamic changes in membership • Support for receiver-initiated, heterogeneous resource reservation

  4. Introduction (cont.) QoS-aware Multicasting using Bounded Flooding (QMBF) • Source-based routing • QoS-aware routing • Feasible path search • Each node exchange QoS information periodically by Bounded Flooding (N=2)

  5. Problem define

  6. Problem define (cont.)

  7. QMBF (Bounded flooding)

  8. QMBF

  9. QMBF (case 1, on tree)
