CNN, too, uses caching and some method of content distribution. I thought that it was AKAM, such as Google's, but a discussion on another board, where AKAM's engineering staff often post, refutes that they are using AKAM. In any event, my guess would be that the author of the article in question didn't see a need to 'break out' the caching component, and automatically lumped the caching component as a part of Google's overall storage and distribution scheme. Does anyone else here know, or better able to explain, the interplay between search engines (Google, in particular) and caching? I suspect caching takes place under various roofings, as I explain below. In addition to serving the distributed storage needs of a particular content host, distributed caching is also a tool that is often used by carriers and SPs to cut down on their outlays for recurring high-capacity bandwidth charges in their own upstream transmission path$. For example, @Home's walled garden network employs extensive distributed caching in order to cut down on client-server distances (thereby economizing on transmission resources and providing a faster screen time), while at the same time enabling them to keep user packets "on net." Thereby lightening the exchange of otherwise heavier amounts of traffic to and from other providers. Okay, it's time for a caching expert to chime in here and answer RAT's questions. Comments, corrections of my own points above are welcome, as well. FAC
