Efficient Network Management System with DACS Scheme

Abstract

Where customers with different membership and position, use computers as in the university network systems, it often takes much time and efforts for them to cope with the change of the system management. This is because the requirements for the respective computer usage are different in the network and security policies. In this paper, a new destination addressing control system (DACS) scheme for the university network services is proposed. The DACS Scheme performs the network services efficiently through the communication management of a client. As the characteristic of DACS Scheme, only the setup modification is required by a system administrator, when the configuration change is needed in the network server. Then, the setup modification is unnecessary by a customer, which shows a merit for both a system administrator and a customer. This paper describes the instruction and the prototype for DACS Protocol as the implementation of DACS Scheme. Then, the simplicity of the system management in DACS Scheme, is examined from the customer and the system administrator viewpoints.

Practical Virtual Use Method of CGI Program for User Creation Personal Portal Page Using DACS Web Service

“…In existing mechanisms, user authentication is performed at this point in time. If access is permitted, information related to the user is searched from data that is accumulated in advance (6). To accumulate the data, there are methods using relational databases or document medium.…”

“…To accumulate the data, there are methods using relational databases or document medium. Following search, the data related to each user are extracted (7). Programs on the Web server side programs that receive the data, such as CGI, generate a Web page dynamically from the data.…”

“…(1) The program on the Web server that the user accesses first is implemented with Web APIs such as Simple Access Object Protocol (SOAP) [20] (2) Communication between (6) and (7) is performed with use of Extensible Markup Language (XML) [26][27] through each Web server distributed on the local area network. The essential commonality of the mechanisms explained by here in Section 2 is that the program on the Web server extracts data from some database and generates the Web page as a personal portal.…”

“…The basic principle of the DACS Scheme is that the entire network system is managed through communication control for each user on the client machine [6]. Moreover, functional extension is achieved by allowing the communication control for each user to coexist with communication control for each client machine to use in a user group [7][8].…”

“…(1) Suggestion of the principle in the DACS Scheme [27] (2) Additional access control function for preventing the access from the physical client that does not have the PEP on it.…”
