Distributed
Environment
APPLI-BUS is built on using standards
like POSIX or TCP/IP. Whatever the network supporting the
TCP/IP protocol (Example: Ethernet, Token Ring, ATM...),
APPLI-BUS can be run on it. APPLI-BUS supplies the users
with many access functions to the different servers.
These functions are to be operated within C, C++ and IDL
language software.
Depending on the needs, APPLI-BUS'
objects are distributed onto the network. Then the
applications work in Client/Server mode. Only a modular
structure allows such an architecture of applications. In
the above mentioned scheme, the opening on the world of
Windows is provided by the Orbix OLE (Object Link
Exchange) Server, which allows APPLI-BUS to exchange data
with an application on top of a PC running Windows 3.11
ou Windows 95.
Client/Server mode
APPLI-BUS supports both synchronous and asynchronous
client/server modes.
Producer/Consumer mode
The consumer subscribes to a notification that the server
is able to send. The producer realizes a mechanism of
polling in freshness instructions (the notifications are
sent only at a change). The consumer then can ask
APPLI-BUS to obtain the notifications sent by the
producer.
