Description:
The openais project is a project to implement a production quality "Revised BSD" licensed implementation of the SA Forum's Application Interface Specification. The project implements cutting edge research on virtual synchrony to provide 100% correct operation in the face of failures or partitionable networks with excellent performance characteristics.

The Application Interface Specification is a software API and policies which are used to develop applications that maintain service during faults. The API consists of Availability Management Framework (AMF) which provides application failover, Cluster Membership (CLM), Checkpointing (CKPT), Event (EVT), Messaging (MSG), and Distributed Locks (DLOCK).
