Collaborative Simulation for Hybrid Networks

An experiment for using more than one simulation of sub-networks collaborating as a single large simulation is suggested, based on work with a similar situation. The background and relevant details of the initial solution are described to provide an outline for the solution. Work on this method will help development of simulations for hybrid networks, where newer pieces may be added to the simulation without having to build a large, monolithic and a site-centric development e ort. This material is based upon work supported in part by the National Science Foundation under Grant No. NSF EEC 94-02384, NASA-GSFC contract number NAS532378, and by the Center for Satellite and Hybrid Communication Networks under NASA contract NAGW-2777, and the State of Maryland. Some of this work was done for a similar situation in an earlier Automatic Network Fault Management project: the time e ciency of the simulations. Eventually, a second approach was suggested there, and the part of the work that did not get used there forms the basis for this note. Also with Department of Electrical Engineering. With the Institute of Systems Research during part of this work.
