A Client-Server Oriented Algorithm for Virtually Synchronous Group Membership in WANs
نویسندگان
چکیده
We describe a novel scalable group membership service designed explicitly for wide area networks. Our membership service is scalable in the number of groups supported, in the number of members in each group, and in the topology each group spans. Our service also supplies the hooks needed to provide clients with full virtual synchrony semantics. Our service attains, on average, a low message overhead by agreeing on membership within a single message round. Furthermore, our service avoids notifying the application of obsolete membership views when the network is unstable, yet it converges when the network has stabilized.

This paper presents a formal design for a novel group multicast service that provides virtually synchronous semantics in asynchronous fault-prone environments. The design employs a client-server architecture in which group membership is maintained not by every process but only by dedicated membership servers, while virtually synchronous group multicast is implemented by service end-points runni...
متن کاملA Virtually Synchronous Group Multicast Algorithm for WANs: Formal Approach
This paper presents a formal design for a novel group communication service targeted for wide-area networks (WANs). The service provides virtual synchrony semantics. Such semantics facilitate the design of fault tolerant distributed applications. The presented design is more suitable for WANs than previously suggested ones. In particular, it features the first algorithm to achieve virtual synch...
