Fault tolerance in distributed computing is a wide area with a significant body of literature
that is vastly diverse in methodology and terminology. This paper aims at structuring the …

This paper presents two variants of virtual synchrony, which are supported by Horus. The
first variant, called strong virtual synchrony, includes the property that every message is …

Distributed systems that span large geographic distances or manage large numbers of
objects are already common place. In such systems, programming applications with even …

We explore the use of different variants of broadcast protocols for managing replicated
databases. Starting with the simplest broadcast primitive, the reliable broadcast protocol, we …

Distributed systems constructed using off-the-shelf communication infrastructures are
becoming common vehicles for doing business in many important application domains …

Existing research on replication is generally based on synchronous replication (all copies
are kept consistent at all times) and update everywhere (any replica can be updated) …

Reducing management costs and improving the availability of large-scale distributed
systems require automatic replica regeneration, that is, creating new replicas in response to …

Abstract System availability is improved by the replication of data objects in a distributed
database system. However, during updates, the complexity of keeping replicas identical …

While it is known that the tensor product of two dimension groups is a dimension group, the
corresponding problem for interpolation groups has been open for a while. We solve this …

We examine algorithmic issues associated with view-synchronous communication (VSC)
group membership in large-scale distributed systems where network partitions may result in …
