Problems solved by technology

In the scenario of full network nodes and a large number of domain names, dynamic route selection needs to calculate and optimize the path in time; especially in the dynamic acceleration scenario, not only the path needs to be calculated in real time, but also the path calculation needs to be performed separately for a huge number of domain names, which causes the CDN system to The calculation pressure is very high, which leads to the high load operation of the CDN system, and the efficiency of back-to-source is low, and the dynamic acceleration effect is poor

Abstract

The invention discloses a CDN system and a source returning method and device thereof. The method comprises the following steps: according an IP address of a CDN node in a CDN system, calculating theshortest path from other CDN nodes to the current CDN node by using a dynamic programming algorithm, and recording corresponding shortest path information, one piece of the shortest path information comprising the path length of the shortest path from one other CDN node to the current CDN node, and the node information of each hop; when source returning is needed, determining a source returning path from a current CDN node to a source station according to the shortest path information, and completing source returning processing through the source returning path; wherein the current CDN node isan edge node of the CDN system. The calculation pressure of the CDN system during back-to-source routing can be reduced, so that the load of the CDN system is reduced.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a CDN system and a method and device for back-to-source. Background technique [0002] When the content distribution network (CDN, Content Delivery Network) system returns to the source, the route is selected according to the domain name, and different domain names require different strategies. In the scenario of full network nodes and a large number of domain names, dynamic route selection needs to calculate and optimize the path in time; especially in the dynamic acceleration scenario, not only the path needs to be calculated in real time, but also the path calculation needs to be performed separately for a huge number of domain names, which causes the CDN system to The calculation pressure is very high, which leads to the high load operation of the CDN system, and the efficiency of back-to-source is low, and the dynamic acceleration effect is poor.
