Effective Transmission of Data Through RBPH for Group Communication-Java project

Pragmatic General Multicast (PGM) is a departure from previous end to end reliable protocols that exploit Internet Multicast. It has both end system and router elements to the protocol. This is an attempt to overcome the scaling problems of protocol reliability techniques (ACK or NAK, retransmission) when operating them over intermittently lossy IP Networks. PGM is targeted at one to many applications, but of course could be used for many to many simply by using multiple sessions.
i) Add IP router alert option handling in the IP packet processing
ii) Add PGM processing

 

"Pragmatic General Multicast (PGM) is a reliable multicast transport protocol mainly aimed for applications that require ordered, duplicate-free, multicast data delivery from multiple sources to multiple receivers. The advantage of PGM over traditional multicast protocols is that it guarantees that a receiver in the group either receives all data packets from transmissions and retransmissions, or is able to detect unrecoverable data packet loss. PGM is specifically intended as a workable solution for multicast applications with basic reliability requirements. Its central design goal is simplicity of operation with due regard for scalability and network efficiency".
