DACS scheme as next generation Policy-based network management scheme

As the work for managing a whole network effectively without a limited purpose, there is the work of PBNM (policy-based network management). 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 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 can not be improved by PBNM. To improve these problems, we show a next generation PBNM which overcomes theses problems and has the function which does not exist in existing PBNM, and called it DACS (destination addressing control system) scheme. By DACS scheme, communication concentration from many clients to PEP is solved, and system updating becomes unnecessary. Moreover, user support at updating the client´s setups and coping with annoying communication by DACS scheme becomes very effective.
