This paper presents the Reliable Multicast Protocol (RMP). RMP provides a totally ordered, reliable, atomic multicast service on top of an unreliable multicast datagram service such as IP Multicasting. RMP is fully and symmetrically distributed so that no site bears an undue portion of the communication load. RMP provides a wide range of guarantees, from(More)
Pragmatic general multicast (PGM) is a reliable multicast transport protocol that runs over a best effort datagram service, such as IP multicast. PGM obtains scalability via hierarchy, forward error correction, NAK elimination, and NAK suppression. It employs a novel polling scheme for NAK delay tuning to facilitate scaling up and down.

We describe a decentralized reconfigurable implementation of a conference management system based on the low-level Internet Protocol (IP) multicasting protocol. IP multicasting allows low-cost, worldwide , two-way transmission of data between large numbers of conferencing participants through the Multicasting Backbone (MBone). Each conference is structured(More)
ragmatic General Multicast (PGM) is a reliable mul-ticast transport protocol for applications that require multicast data delivery from a single source to multiple receivers. PGM runs over a best effort datagram service, such as IP multicast. PGM guarantees that a receiver in the group either receives all data packets from transmissions and repairs, or is(More)
The Reliable Multicast Protocol (RMP) provides a unique, group-based model for distributed programs that need to handle reconnguration events at the application layer. This model, called membership views, provides an abstraction in which events such as site failures, network partitions, and normal join-leave events are viewed as group reformations. RMP(More)
