MESIS: the Agent Interoperability Facility (1)

Management Environment for Secure and Interoperable Services

CORBA is the most widely accepted technology to overcome network, platform and programming language heterogeneity and has acquired a central position in the evolution of telecommunications environments.

Within the MESIS DPE, the AIF module implements full compliance with CORBA. This compliance introduces some overhead, but the resulting openness and component stability to applications represent an invaluable saving of investments in the design of services. The AIF facility is implemented by the CORBABridge add-on that is composed by two modules, the CORBA Client/Server and the MASIFBridge. The AIF facility permits to achieve interoperability along the following directions (see Figure 3):

1. a MESIS DPE component may call any CORBA DPE component or any service with a published CORBA interface by means of the CORBA Client/Server module (MESIS as CORBA clients);

2. any service, whether MA-based or not, may exploit the CORBA Client/Server module to call MESIS DPE services, which publish CORBA standard interfaces (MESIS as CORBA servers);

3. MESIS DPE may interwork with any other MASIF-compliant MA DPE via the MASIFBridge (MASIF Interoperability).
