ISP(Internet Service Provider)是向广大用户提供Internet接口与相关服务的机构。ISP有两大类:一类为只向用户提供拨号入网的IAP(Internet Access Provider),它规模小,局域性强,向用户提供的信息服务有限,一般没有自己的骨干网络和信息源,用户仅将其作为一个上网的接入点看待。另一类是ICP(Internet Content Provider),它能为用户提供全方位的服务,可以提供专线、拨号上网,提供各类信息服务和培训等,拥有自己的特色信息源,它是ISP今后发展的主要方向,也是未来Internet建设的重要力量。到目前,国内ISP有100多家(据说待批的还有300～400家),总投资达20亿元(不包括四大互联网),入网计算机数超过5万,用户数已逾15万。但因为我国ICP很少,用户数没有大规模增加,通信资费不合理,致使ISP巨额投资几乎全部亏损运营,严重制约了中国Inter-

However, due to the fact that there are few ICPs in our country, the number of users has not increased by a large scale, and the unreasonable communication charges have caused almost all of ISPs’ huge investments to operate at a loss. This has severely restricted China’s Inter-
