|Abstract:||This dissertation is to describe the newly architecture of a Reliable Multicast Protocol (RMP) for providing reliable services at PIM-SM domain. In this approach, the protocol selected the appropriated PIM routers located at the branch for handling the NAK packets from the group members and providing the data re-transmission. RMP introduces the new term "NAK Responder" which actually is a PIM router selected for caching the sender's packets to provide the reliable services with the group members at the branch at which the NAK Responders is located. This protocol can also minimize the NAK implosion by increasing the group members because NAK packets sent from the group members are handled by the individual NAK Responder located at those branches which group members are connected. It also describes the protocol details including the definition of packet type used at RMP, procedures processed by the entities of Sender, Receiver, Rendezvous Point and PIM Router as well as the packet formats. Regarding to the Simulation Result section, it demonstrates the performance metrics including Data Loss Recovery Time, Traffic Concentration and Scalability once the RMP is introduced into the PIM-SM domain for providing reliable service. At the Conclusions Sections, this protocol can be further enhanced to reduce the overhead and made more effective once the existing PIM-SM protocol can be extended for adding some state information of the branch on it.|
