We describe our collaborative efforts towards the design and implementation of a next generation integrated network management system for hybrid network (INMS/HN). We describe the overall software architecture of the system at its current stage of development. This network management system if specifically designed to address issues relevant for complex heterogeneous networks consisting of seamlessly interoperable terrestrial and satellite networks. Network management systems are a key element for interoperability in such networks. We describe the integration of configuration management and performance management. The next step in this integration is fault management. In particular we describe the object model, issues of the Graphical User Interface (GUI), browsing tools and performance data graphical widget displays, management, information database (MIB) organization issues. Several components of the system are being commercialized by Hughes Networks Systems.
