  1. A Survey and Comparison of Overlay Multicast Ching-Feng Li

  2. Introduction • Different applications have different characteristics which may have influence on the design choice of overlay multicast techniques • Survey several existing overlay multicast techniques and give a brief comparison of them

  3. Comparison of different overlay multicast techniques

  4. Example applications and their characteristics

  5. Factors that affect choice of multicast technique • Scalability • Fault tolerance • Performance • Quality of service • Security

  6. Choice of overlay multicast tree in development phase • Mobile agents can be easily deployed to implement different algorithms of overlay multicast tree construction and maintenance • Purpose: to compare the performance of different algorithms

  7. Adaptive reconfiguration of multicast tree (1/2) • Adaptive reconfiguration of host-based multicast tree • Mobile agent can migrate adaptively according to the load of resident host • After mobile agent migrates, the configuration of multicast tree won’t change at once • After mobile agent migrates, it reconfigures the multicast tree at the new resident host if necessary • If the configuration of multicast tree changes, mobile agent will notify the old resident host

  8. Adaptive reconfiguration of multicast tree (2/2) • Adaptive reconfiguration of agent-based multicast tree • Mobile agent can migrate adaptively according to the load of resident host • After mobile agent migrates, the configuration of multicast tree will change at once • After mobile agent migrates, it acts as a data transmission proxy for the old resident host at the new resident host

  9. Issues • How many agents will be used? • How to distribute the agents to the host? • How to handle agent migration for reconfiguration of multicast tree?
