Virtual Use Method of CGI by DACS Web Service Based on the Next Generation PBNM Scheme Called DACS Scheme

as a 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 troublesome user support in updating a client’s setups and coping with annoying communication cannot be improved by the PBNM. To improve these problems, we have been studied a next generation PBNM, which overcomes theses problems and has the function that 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, to raise the effectiveness of this scheme, we show a virtual use method of CGI (Common Gateway Interface) by using the DACS Web Service, which is the Web Service realized by the DACS Scheme that we have been proposed before.
