III Managing CORBA-Environments with SNMP Platforms

  The CORBA-based management of LEO/MEO satellite constellations through ground stations (as described in section II) implies the availability of a CORBA-based management platform. Although several platform vendors claim to deliver CORBA-compliant management platforms, this statement is in almost every case only true for the internal platform communication mechanisms: These systems are based on a proprietary ORB and are thus not CORBA-2.2 compliant, i.e. they cannot inter-operate with other ORBs and therefore not with CORBA agents located on remote devices. It is therefore necessary to enhance SNMP-based management platforms for handling CORBA requests. This section discusses the principal alternatives for bridging the gaps between different management architectures and describes the concept of our solution based on platform services and standardized CORBAservices.
