ModernDepartmentofDefense C4I systems utilize high speed commercial computer networks,
composed ofcommercial equipment and connectivity. The United States Special Operations Command
(USSOCOM) SCAMPI (not an acronym)Networkwas aforerunnerofthis trend. Industry uses the same
type ofcircuits but approaches thenetwork management ofthese circuits from a financial interestversus
the military strategic and tactical aspects considered by the service user. This thesis analyzes this
representativenetwork in the contextofindustrynetwork management and metrics practices. The thesis
first surveys and explains the industry practices most prevalent in this changing environment and then
examines the practices in place at USSOCOM. The compilation ofindustry wide network management
and metrics procedures is followed by a series ofproblem/solution recommendations forthe SCAMPI
network. These recommendations are explained in the context ofcurrent industry practices. This is
followedby aseries ofemergingindustrytrends and technical developments which most likely will affect
the implementation ofnetwork management and metrics tools. These developments are followed by a
comprehensive industry definitions section, network bibliography, and a hypertext link guide to current
military, industry and educational institutions networking solutions.

ABSTRACT MC' CA 93044,01
Modern Department ofDefense C4I systems utilize high speed commercial computer
networks, composed ofcommercial equipment and connectivity. The United States Special
Operations Command (USSOCOM's) SCAMPI (not anacronym)Networkwas aforerunner
of this trend. Industry uses the same type of circuits but approaches the network
management of these circuits from a financial interest versus the military strategic and
tactical aspects considered by the service user. This thesis analyzes this representative
networkin thecontext ofindustry network management and metrics practices. The thesis
first surveys and explains the industry practices most prevalent in this changing
environment and then examines the practices in place at USSOCOM. The compilation of
industry wide network management and metrics procedures is followed by a series of
solutionrecommendations forthe SCAMPI network. Theserecommendations are explained
in the context of current industry practices. This is followed by a series of emerging
industry trends and technical developments whichmostlikely will affect the implementation
of network management and metrics tools. These developments are followed by a
comprehensive industry definitions section, network bibliography, and a hypertext link
guide to current military, industry and educational institutions networking solutions.
