Design and Performance Analysis of Open-Internet Access System Providing the Functions of Vicarious Certification and Billing Agent In An Web Infoshop Service of Advanced Information Communication Processing System

摘要

Nationwide advanced information communication processing system (AICPS), as a network node, links various user terminals, over ordinary public switched telephone network (PSTN), to information providers (IPs). IPs are connected to the public switched data network (PSDN) to provide the value added network (VAN) services to the subscribers. Through the AICPS systems, subscribers can easily get information services using only modems without any extra devices. The AICPS system has been promoting a more information-oriented society in Korea. The function of AICPS systems provides interconnection among various heterogeneous access networks and value-added information service to subscribers. The main goal of AICPS system is to construct the information infrastructure for open computing services that can support heterogeneous network connections and its value-added communications. There are many nodes to handle the operational and manageable functions in local center for AICPS systems. Each node must gather the data for operation and management such as node configuration, activities against fault condition and interaction with the local center for reporting node status. Also this paper focuses design and performance analysis of an open Internet access system to interconnect various access networks in an AICPS system.
