The present invention is directed to a network switch that determines when
specific content is hot and directs flow to one or more cache servers.
The architecture can include a tag generator to generate unique tags
corresponding to a server in a plurality of servers, a content
pre-fetching algorithm to retrieve information before the information is
requested by determining the hotness of the information, and a cache
server in which stored information is configured based upon the relative
degrees of hotness of the stored information.
