  1. Incremental Service Deployment Using the Hop-By-Hop Multicast Routing Protocol By M.K Costa, Serge Fdida and Otto Carlos -Shwetha Bangalore Krishnakumar 2427894

  2. Buzz Words • Unicast / Multicast • Router and Routing • MCT and MFT

  3. Importance • Tradeoffs • Solutions

  4. Basic Principles of HBH • Related work • EXPRESS • REUNITE • Multicast Distribution through recursive unicast • Risks of Asymmetric Unicast Routing • Problems with the Operation of REUNITE

  5. Multicast Distribution through recursive unicast

  6. Risks of Asymmetric Unicast

  7. Problems with the Operation of REUNITE • Interception of join messages • Packet duplication due to asymmetric routes in REUNITE • Temporary loop creation

  8. HBH Multicast Protocol • Has better tree construction algorithm with three control messages: Join, Tree and Fusion • MCT and MFT( with a different meaning) • Channel <S,G> solves address allocation problem • Produces n modified copies • Departure of a receiver has lesser impact

  9. Operation of HBH

  10. Performance Analysis • Performance of HBH improves with the number of HBH routers in network • With 60% HBH routers, the performance is close to the one obtained using 100% HBH routers.

  11. Finally, • HBH supports unicast clouds • Allows incremental deployment • Provides lower cost trees in the cases where REUNITE construction fails • Guarantees that members receive data through the shortest path from the source • Member departure has minimum impact on the tree structure
