The Internet Cache To Accelerate Research And Application System

Today, the rapid development of the Internet, surfing the Internet has become an indispensable part of people’s life, it can be used to browse the Internet and transfer of information, transfer of business activity information, and has been called "the fourth media. For example, rely on a network of online business, in a few minutes or even seconds can be a large number of important data service. It is precisely because of the popularity of the Internet, users of it depends on more and more big, requirements are also getting higher and higher, so the browsing speed slow, the response time is long, the effect is poor with Internet user complaints come one after another.We will of course take relevant technical measures (such as increasing the bandwidth, the replacement of faster processing server etc.), but after the huge investment has not received very good results. In order to speed up access, many large websites even tried in all over the building of the mirror, although in theory can solve these problems, but this method greater investment and management difficult, very difficult to be. So we began to explore how to speed up the access network and the response in the existing conditions, the investigation found, Internet traffic generated is very large, and many users in the same position of a query a large number of identical content, thus creating the redundant data of a large part of the encroachment of limited bandwidth. This suggests that, if can eliminate these repeated transmission on the Internet at the same content, can effectively reduce the cost, save the cost of enterprise and service provider.On a visit to cyber source, and many other factors, resulting in delay of each connection link, therefore, we need a new technology:it is convenient and flexible, easy to configure and manage, closer to the end user, store frequently accessed content, but without the need to continue the server and network bandwidth upgrade, this structure is called the Web cache.Web caching technology is key to cyber source node is cached (node includes local resources), but not in the wide area network repeat pass query command and query results, provides efficient service for the user’s query and browse.
