As the work for managing a whole network effectively without a limited purpose, there is the work of a PBNM (Policy-based network management). The PBNM has two structural problems such as communication concentration from many clients to a communication control mechanism called PEP (Policy Enhancement Point) and the necessity of the network system updating at the time of introducing the PBNM into LAN. Moreover, user support problems in campus-like computer networks such as trouble user support at updating a client's setups and coping with annoying communication cannot be improved by the PBNM. To improve these problems, we have been shown a next generation PBNM which overcomes theses problems and has the function which does not exist in the existing PBNM, and called it a DACS (Destination Addressing Control System) Scheme. By the DACS Scheme, communication concentration from many clients to the PEP is solved, and system updating becomes unnecessary. Moreover, user support at updating the client's setups and coping with annoying communication by the DACS Scheme becomes very effective. In this study, we implement a DACS system to realize a concept of the DACS Scheme.
