为了以变通方式解决带宽问题,使用网络缓存,ISP可以通过一个活动的缓存将用户最常用的web站的内容保存到ISP的本地。当用户对缓存的web站进行访问时,就可以将缓存中的内容发送给用户。而无须路由到实际的web站,这样可以显著提高访问的速度。 一些国际组织准备推出一种新的缓存结构,例如:如果一个中国的用户需要访问位于英国的URL。那么该用户的个人浏览器需要先察看该URL是否还存在本地的硬盘中。如果没有的话,则检查是否还存在网络中。依次的检查顺序是:中国地区缓存区,中国国家缓存区,英国缓存区。如果还没有发现的话,浏 In order to work around the bandwidth problem in a workaround, using network caching, the ISP can save the content of the user’s most used web site locally to the ISP through an active cache. When a user accesses a cached web site, the content in the cache can be sent to the user. Without having to route to the actual web site, this can significantly increase the speed of access. Some international organizations are preparing to launch a new caching structure, for example, if a Chinese user needs to visit a URL located in the United Kingdom. Then the user’s personal browser needs to check whether the URL still exists in the local hard disk. If not, then check if there is still in the network. The order of check is: China buffer area, China National buffer area, the British buffer area. If you have not found it yet, browse
