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