In the Internet, the IXP (Internet Exchange Point) /s tend to be congested since all traffic must go through the IXP's if the ISP (Internet Service Provider) 's belong to the different upper ISP's. In particular, this problem is serious in Japan since we have only a few IXP's. To ease this problem, we focus on the HTTP traffic exchanged among the neighboring ISP's since the web browsing causes major traffic in the Internet. In this paper, we provide a structure of regional HTTP-IXP and its experimental results. Our HTTP-IXP system aims to reduce the backborn traffic with comparatively low cost by exchanging the regional HTTP traffic via HTTP cash server. Our experimental results show that the backborn traffic can be reduced without the degradation of any user QoS (Quality of Service).
