View Synchronous Communication in Large Scale Distributed Systems
View synchronous communication (VSC) is a paradigm initially proposed by the Isis system, that is well suited to implement fault-tolerant services based on replication. VSC can be seen as an adequate low level semantics on which ordered multicasts and uniform multicasts can easily be implemented. This paper presents the specific problems related to the implementation of VSC in a large scale network (e.g. Internet). The paper also shows how these problems are solved within Phoenix, a group oriented platform under development. Specifically the Phoenix implementation of VSC allows progress in cases where traditional solutions would block forever.
