This research is aimed at developing theoretical and experimental               understanding of the application of atmospheric optical communication           links in local area networks.  In theoretical work to date, the use of          a variable transmission-rate atmospheric optical link to provide                graceful network performance degradation in the face of weather-induced         optical link performance degradation has been analyzed.  In                     experimental work to date, development of an atmospheric optical                link/local area network test bed has been undertaken.  This research            will continue the dual thrust of theoretical and experimental studies           of atmospheric optical communications in local area networks.  The              theoretical work will treat:  transport-layer job management                    procedures; topologies and control procedures for combined                      atmospheric-optic/fiber-optic very high data rate networks; and optical         broadcast networks.  The experimental work will concentrate on ring             network operation, featuring gateway interconnection of an atmospheric          optical 2-node network into a working ring network environment.                 Experimental work will also begin on bus network applications.
