Smart Proxies in LuaOrb: Automatic Adaptation and Monitoring

Noemi RodriguezHelcio Mello

The LuaOrb project uses reflective features offered by the Lua programming language and by CORBA itself to create a platform that combines simplicity and flexibility in its support for dynamic behavior. In this paper we describe ongoing work on smart proxies. Smart proxies, based on simple QoS descriptions and event-based monitoring facilities, substitute traditional stubs, but automatically react to changes in run-time conditions, The paper also discusses support for dynamic stubs, which can implement generic adaptation procedures or performance-enhanced access to servers. Finally, we discuss an example of dynamic adaptation with smart proxies.
