项目摘要

We proposed PIX or Pseudo Internet eXchange that is a model for exchanging traffic of the Internet. A network according to PIX exchanges traffic on the application layer of the network and resolves regional traffic exchange in a prepared regional intranet. We have had some technolongical issues of PIX.The purpose of this research is finding out solutions of the issues.We firstly had constructed an experimental network, named KPIX, connecting to eight organizations at Kochi prefecture to perform the research. Each organization has an own connection to the Internet and is connected each other via wireless communication units.One of the topics is collision of private IP addresses or Acceptable Use Policies (AUPs) in a regional network. We proposed to adapt network Address Translation (NAT) and tunneling by IPsec to solve the topic and have made an implementation on KPIX.Second topic is how to share contents on application layer. We proposed about WWW servers combination that preserves an access control on the WWW servers. We also show an implementation on KPIX.Last topic is cost of maintaining a PIX based network. We proposed a cost model of PIX by an amount of connection fee variations to an intranet and the Internet where the total traffic is same. An analysis of the cost model concludes PIX takes advantage if the total traffic is larger and a ratio of the intranet traffic is greater.

我们提出了PIX或伪互联网交换，这是一个模型，用于交换互联网的流量。根据PIX的网络在网络的应用层上交换业务，并在准备好的区域内联网中解决区域业务交换。本研究的目的是解决PIX的技术问题。首先，我们构建了一个实验网络，名为KPIX，连接到高知县的8个组织进行研究。每个组织都有自己的互联网连接，并通过无线通信单元相互连接。其中一个主题是区域网络中私有IP地址或可接受使用策略（AUP）的冲突。本文提出了采用网络地址转换（NAT）和隧道技术来解决这一问题，并在KPIX上实现了这一方案。第二个问题是如何在应用层实现内容共享。我们提出了关于WWW服务器的组合，保留了对WWW服务器的访问控制。最后一个主题是维护基于PIX的网络的成本。我们提出了一个成本模型的PIX的连接费用的变化量的内部网和互联网的总流量相同。成本模型的分析得出结论，PIX的优势，如果总流量较大，内部网流量的比例较大。
