Evaluating light-weight reliable multicast protocol extensions to the CORBA event service

The article proposes and evaluates some extensions to the CORBA event service, based on the use of the light-weight reliable multicast protocol (LRMP). These extensions address some limitations of the CORBA Event Service, namely multicasting, reliability and total ordering. The extensions were developed and tested in a prototype environment created for this purpose, and are transparent and fully compatible with the standard OMG event service, enabling the user to decide on the use of standard IIOP or IP multicasting.
