	abstract = {Hybrid communication networks provide an economically feasible and technologically efficient means to implement the global information infrastructure. The management of such heterogeneous networks is a critical market differentiator for telecommunications companies and a formidable technical task. In this paper we describe our efforts in the Center for Satellite and Hybrid Communications Networks, to design and implement an integrated network management system for such networks. The major accomplishments to date are the design and implement an integrated network management system for such networks. The major accomplishments to date are the design and implementations of an object oriented data model for hybrid networks consisting of satellite networks and terrestrial ATM networks; the extension of the system to hybrid networks with as many as 300,000 nodes; the development of browsing graphical tools so that mesh-connected graph networks (as opposed to tree networks) can be efficiently queried; specifically designed graphical widgets for displaying performance data continuously from the network management information database (MIB); extensions of the GUI to distributed operation including appropriate designs for consistency and concurrency between the GUI display and the network MIB;~storage and organization issues for performance data in the MIB; integration of configuration management and performancce management.},

	abstract = {Commercial and military networks are rapidly becoming hybrid networks;~that is interconnected wireless terrestrial, wireline terrestrial and satellite networks. There is a great need for software tools to design, model and also do performance analysis efficiently for such large heterogeneous networks. This is the topic addressed in this paper. The hybrid network modeling and performance evaluation tool is currently under development at the University of Maryland. The tool consists of an algorithmic structure and a software architecture. The algorithm is hierarchical in form, deriving its structure from that of the network which follows the network{\textquoteright}s routing hierarchy. At each level, a node represents a set of nodes at a lower level. The boundary of a node is characterized by a set of statistical models. The statistics and their parametric representations for the models of the level 1 nodes are obtained from the OPNET simulations which are run offline. The model defines procedures that convey modeling, simulation and performance data up and down the hierarchy of models. We consider the following performance metrics only: end-to-end delay, throughput, blocking probabilities, cell or packet loss rate. We describe algorithms based on loss network approximations and fast progressive solutions of resulting fixed point equations.},

This software incorporates a complex system simulation paradigm, advanced visualization techniques, a flexible interface and an object-oriented database to allow the simulator to be used not only as a network simulation tool, but also as a network design tool, as a network performance evaluation tool, and as part of an intelligent network management software.},
