Embodiment Construction

[0011] High-quality CDN services must be reflected in the experience of end users. For small and medium-sized enterprise users who pay great attention to the distribution speed of file content, a large number of CDN services can be used.

[0012] The IPTV system has high requirements for the quality of service of users, and it must ensure smooth playback. In the wide area network, after a very complicated route has passed between the user's client terminal and the streaming media server, it is difficult to ensure smooth playback. In order to overcome the constraints brought by complex network routes, edge services must be used in IPTV to realize end-user on-demand services. Therefore, to effectively distribute content from the central server to the edge server, the content can be distributed from the central storage server through CDN to the edge server.

[0013] Streaming media technology is a technology that allows users to start browsing or playing streaming media without...

Abstract

A working process of a content delivery network (CND) comprises that when a user visits a website which has joined in a CDN service, an optimum CDN nodal point which is closest to the user is determined by using a CDN re-direction technique and request of the user is enabled to point to the nodal joint. When a nodal point of the user arrives at the designated nodal point, a server (cache of the nodal point) of the CDN is responsible for providing content which the user requests for the user, namely that the user inputs the realm name of a website which the user visits on a browser of the user, the browser requests a local DNS to analyze the realm name, the local DSN sends the request to a main DNS of the website, the main DNS determines the optimum CDN nodal point at that moment by adopting a series of strategies and sends an analyzing result (internet protocol (IP) address) to the user and the user asks the designated CDN nodal point for the content of the corresponding website. The CDN system is capable of sending the content to the user in a high-efficiency way by judging user accessibility and server load. A good service can be provided for the user.

Description

technical field [0001] The present invention is based on the research on the method of realizing network acceleration by using CDN (Content Delivery Network) technology based on the integration of three networks. Request network requirements from designated nodes, involving technical fields such as computer networks and databases. Background technique [0002] The so-called triple play refers to the three major networks of telecommunication network, computer network and cable TV network through technical transformation, mutual penetration and mutual compatibility, and gradually integrated into a unified information communication network, providing integrated multimedia communications including voice, data, images, etc. business. The integration of triple play is the long-awaited expectation of people in the information age. The realization of triple play can combine the last "one kilometer" line connecting users into one. The integration of three networks can integrate pe...
