Goolge's ability to manage massive amounts of memory is increasing (just to keep up the stack of PCs:)). There is such a large-scale distributed system, nodes distributed throughout the country, the system for the delivery of Internet content is obvious. So what is missing, of course, a national IP backbone can be covered. That's why Google, a website company, wants to buy a fiber-optic backbone across the United States. Manufacturing more than tens of thousands of nodes of distributed comput

always in one place, and when your users visit your site in other parts of your country or in other countries, their pages may take a long time to load because they are too far apart from the client and server. After all, we're talking about "the World Wide Web", not "local".The popular strategy is to use a Content distribution network (CDN), a large "proxy" server distributed system that is deployed in multiple datacenters. A proxy server is just an intermediary server that acts as a client an

application architecture and focus on decentralized static content. While this does not result in significant time savings, it is easy to implement with the help of content distribution networks. The so-called Content distribution network (Delivery NETWORD,CDN) is a collection of Web servers in which servers are distributed in different locations to distribute content more efficiently to users. A server that is ultimately determined to distribute content to users is usually based on measurement

, it is better to distribute static content first. This not only greatly reduces the response time, but also makes it easy to implement distributed static content due to the presence of CDN.CDN is a collection of geographically distributed Web servers for more efficient content publishing. Generally, the web server is selected for a specific user based on the network distance. Some large websites have their own CDN, but it is cost-effective to use services provided by CDN service providers such

adaptation template ensures that only the necessary resources are loaded on the user's terminal. Because device detection is moved to the mobile terminal to detect itself, CDN networks, such as Akamai and EdgeCast, can use most of the caching capabilities without disrupting the user experience. The client adaptation method has a higher threshold than the response design in use. Developers need a solid JavaScript base to use this technology. It also

occurs, the connected device may need to configure the dual-Stack: IPv4 address and IPv6 address. Old devices that do not support IPv6 addresses may cause network communication problems and eventually become a burden. Where is IPv6 today? People may not realize that there are already more than 9 million domain names and more than 20% of the networks already use IPv6 connections. Many companies (such as Comcast, Verizon, and other cellular service providers) Use IPv6. According to Google statist

But surprisingly, in this experiment, traffic and investment were reduced by 20%, apparently because more search results resulted in more than half a second to load the page. ^5The user's expectations are always rising. In 2009, a study by Akamai, a Forrester Institute, found that the threshold for Web page response time was 2 seconds, and that 40% of
