The objectives of this research is to show how to quickly innovate the public network to the multimedia-based network taking advantages of downsizing of switching systems, and to present a micro-switching network architecture suitable for the purpose. The remarks of the obtained results of the research are as follows ;The internet access through the public network can be a carrying vehicle for the network innovation. Immigration of the internet services into the public network must be an evolution of the public network. The distributed micro-switching network should provide functions for efficient and high-speed internet access.The micro-switching network adopts tree topology to accommodate large amounts of subscribers randomly scattered over the wide area. Cell-based signaling systems should be developed to minimize call connection delay due to the distribution of switching systems, and to reduce hardware volume of thr tandem switch. Fundamental specification of the cell-based signali … More ng system is established.A router for the internet access should locate at the distributed subscriber node to use the besteffort services for the internet access. The upward stream of the internet access uses signaling facilities ; the D-channel signaling system in the subscriber loop, and cell-based signaling systems in the tandem network. The downward stream utilizes the tandem link shared by many users. The sequential-write and random-read function in a simple one-stage time switch allows packet-by-packet multiplexing and broadcasting of the IP packets. The research also pointed out the necessity of selective downloading functions for the IP broadcasting, this is because any IP packet for some user should not reach custom premises of other users'. The services are of the public network, not of LAN in a private area. The fundamental configuration of the selective downloading facilities are also demonstrated. The architecture fits the ADSL technology which is a hopeful technology for metallic subscriber loops.Technology which is a hopeful technology for metallic subscriber loops. Less

本研究的目的是展示如何利用交换系统的小型化，快速地将公共网络改造成基于多媒体的网络，并提出一种适合于此目的的微交换网络结构。对研究成果的评述如下：通过公共网络接入互联网可以成为网络创新的载体。互联网服务向公共网络的迁移必然是公共网络的一种演进。分布式微交换网络应提供高效、高速的互联网接入功能。微交换网络采用树型拓扑结构，以容纳随机分布在广域上的大量用户。应发展基于蜂窝的信令系统，以减少由于交换系统的分布而引起的呼叫连接延迟，并减少汇接交换机的硬件体积。基于信元的信号的基本规范 ...更多信息 在分布式用户节点上设置一个用于Internet接入的路由器，以提供最佳的Internet接入服务。互联网接入的上行流使用信令设施;用户环路中的D信道信令系统和汇接网络中的基于信元的信令系统。下行流利用由许多用户共享的汇接链路。简单的单级时间交换机中的顺序写入和随机读取功能允许IP数据包的逐包复用和广播。研究还指出了IP广播选择性下载功能的必要性，这是因为某些用户的任何IP数据包都不应该到达其他用户的客户端。服务是公共网络的，而不是私有区域的LAN。选择性下载设施的基本配置也被证明。该体系结构适合于ADSL技术，这是一种很有希望的金属用户环路技术。少
