Abstract:
Group communication systems (GCSs) are now widely recognized as
powerful building blocks for supporting consistency and
fault-tolerance in distributed applications. In this paper we present
a novel GCS called Xpand. The main objective of the Xpand design
is to address the needs of a wide spectrum of collaborative wide area
network applications without compromising the semantics of traditional
GCSs to the extent possible. In order to achieve this goal Xpand
introduces a separation between strong and weak service levels, a
scalable failure detection, an external infrastructure for membership
maintenance and hierarchical engine for message reliability.
