Abstract
As the work for managing a whole LAN effectively withoutlimited purposes, there are works of Policy-based networkmanagement (PBNM). The existing PBNM is defined in someorganizations including the Internet Engineering Task Force(IETF). However, it has structural problems. For example,communications sent from many clients concentrate on acommunication control mechanism called PEP (PolicyEnforcement Point). To improve the problems, we have beenstudying next generation PBNM called Destination AddressingControl System (DACS) Scheme. The DACS Scheme controlsthe whole LAN through communication control by the clientsoftware as PEP which locates on a client computer. We havebeen studied on the aspect of principle until now. In thisresearch, we implement a DACS system to realize a concept ofthe DACS Scheme, and show implement method and results offunctional experiments.
Highlights
In enterprise computer networks, because network policies and security policies are well defined and are observed forcibly, network management is relatively easy
Third problem is that it is often difficult for the Policy-based network management (PBNM) to improve the user support problems in campus-like computer networks explained above. To improve these problems of the PBNM, we show a generation PBNM, which overcomes these problems and has the function which does not exist in the existing PBNM
As the works of Destination Addressing Control System (DACS) Scheme, we showed the basic principle of the DACS Scheme [20], and security function [21]
Summary
Because network policies and security policies are well defined and are observed forcibly, network management is relatively easy. Because a computer management section manages only a part of the campus network, there are some user support problems. As the works on network management, various kind of works such as the server load distribution technology [1][2][3], VPN (Virtual Private Network) [4][5] are listed. These works are performed forward the different goal, and don’t have the purpose of effective management for a whole LAN. As the work for managing the whole net-work, works on Opengate [6][7] are listed This is a kind of Policy-based network management (PBNM).
