Global content distribution method and system

Abstract

The invention relates to a global content distribution method. The method comprises a source station server, a global load balancing cluster in communication connection with the source station server, and a plurality of GCDN (Global Content Delivery Network) node servers; an access method comprises the following steps: step A, sending a domain name resolution request of a user to a local DNS (Domain Name Server); step B, making the request be directed to a GCDN global load balancing cluster through a GCDN intelligent DNS cluster; step C, performing intelligent resolution on a requested domain name, and returning a GCDN edge cluster IP (Internet Protocol) with the corresponding fastest speed to the local DNS; step D, returning a received IP address to the user by the local DNS; and step E, accessing a GCDN node by the user by using the returned IP address and directly responding to the user. A local Cache is used for accelerating a GCDN global network mirror and an acceleration engine, and through a high-speed compression channel and a cluster anti-attack technology, load balancing and intelligent multi-thread of the network are achieved and a fastest path can be automatically obtained.

Description

technical field [0001] The invention belongs to the field of Internet technology improvement, and in particular relates to a method and system for global content distribution. Background technique [0002] First of all, the traditional DNS resolution process does not prejudge whether the server is working properly when converting the domain name of the website host to an IP address; even if the server is down and cannot provide services, user requests will still be sent to this server , resulting in interruption of service. [0003] Secondly, from the very first day of the birth of the Internet, it lacked a dedicated central management structure, and also lacked unified product and technical standards. This was once the advantage of the rapid development of the Internet. However, with the increasing scale of the global Internet, this has created a situation where many different network structures coexist. Issues such as compatibility between networks in different countrie...

However, with the increasing scale of the global Internet, this has created a situation where many different network structures coexist

Issues such as compatibility between networks in different countries and transmission bottlenecks between different network operators limit the flow of data

According to statistics, the average international transmission rate on the existing Internet is not higher than 30Kbps

[0004] In addition, the existing Internet is based on data packet transmission, any data packet loss or error must be resent, and an average retransmission process takes 3 seconds, resulting in delay

Moreover, the existing HTTP protocol also has factors that induce delay. According to investigations, to download a webpage completely, it needs to go back and forth between the user and the server 20 to 100 times.

[0005] Finally, the existing routing technology determines the transmission path of the current data packet based on the historical data of the working status of the router, which cannot truly reflect the current routing and network connection status

This often results in data transfers taking a path that is not currently the best path

Moreover, numerous routers and switches not only increase the time delay of data transmission, but also increase the probability of errors, because any problem with any router will affect the entire transmission process.
