Appli-Bus is a high-performance, fault-tolerant framework for building
object-oriented distributed applications. Corba IIOP is used as the wire
protocol. Appli-Bus provides a publish and subscribe distributed event model. It
uses primarily a peer to peer model of communication so that
"clients" of services can receive notifications
asynchronously and also act as service providers. The base of Appli-Bus is an access
server which is an application server like container that provides support
for fault tolerance, synchronous calls, asynchronous send and receive, and
subscriptions. It provides plug-in APIs for both clients and servers.
On the 31st January 2001 Applibus went Open Source. The Open
Source site has more information on the architecture and the programming
model and interfaces.
