| QoS multicast routing plays a critical role in supporting multicast applications with QoS requirements. In this thesis, we present an active QoS multicast routing protocol using distributed agents(AQMR). AQMR introduces several new ideas for QoS multicast routing, which gives it the features of QoS awareness, scalability, responsiveness and efficiency. Agents store QoS information of the multicast tree in a scalable and flexible manner to facilitate member joins. AQMR employs an admission control scheme that enables it to better meet QoS requirements. It achieves low join overhead and low join latency. In addition, AQMR constructs a resource-efficient multicast tree. A performance study shows that AQMR can provide better QoS for receivers than QoSMIC. |
