| Multicast with QoS guarantee is a resource-efficient transmission scheme for the delivery of multi-participant multimedia applications. In this thesis, we present MRMA a multicast resource management architecture designed to provision multicast service with QoS guarantee over the IP platform. Unlike most other related work, which focuses primarily on the algorithmic or protocol aspects of the multicast problem, our work focuses on the architecture and implementation aspects pertaining to the setup and configuration of multicast sessions with QoS guarantees. MRMA offers a flexible platform for integrating the necessary components for implementing the key multicast functions that are needed for creating, maintaining and terminating multicast sessions: route selection, address allocation, session advertisement, and QoS-sensitive tree construction. MRMA implements a hierarchical architecture that features centralized monitoring of network state and semi-distributed per-session multicast management which allows it to achieve a good balance between accuracy and scalability. |
