Multicast technology is highly efficient for the large scalemultimedia content service delivery. Its efficiency is maximizedwhen all the service recipients have identical needs.In reality however, the end users may have a heterogeneousset of requirements for different service levels as well asdifferent service components, depending on their systemand network capabilities. We propose the notion of ServiceAdaptive Multicast (SAM) that balances the tradeoffsbetween providing individualized service to each client andmaintaining an efficient overlay multicast tree structure.The novel aspects of our approach are (a) the ability to augmentand transform existing paths into service paths withthe desired attributes; and (b) integration of two tree maintenanceprocesses: a receiver-initiated just-in-time adaptationof the multicast service tree driven by application/userperceived QoS, and a demand-driven tree maintenance processgeared towards long-term tree quality. We demonstratethe performance of our approach using simulations of largeclient population.
