The study of DACS Scheme, which manages a whole network system by communication control on a client computer, has been advanced. The problem for applying DACS Scheme to practical network is that, processing load is heavy at the time of controlling communication. In this paper, we propose models for managing a whole network system; Course management type model (COMTM) and Client management type model (CLMTM). Each processing load which occurs at the time of controlling communication in these two models is compared. It is shown that, DACS Scheme which is CLMTM is advantageous in comparison with COMTM from the point of processing load, which occurs at the time of control communication.
