Problems solved by technology

In this architecture, the CDN node closest to the user is actually the CDN node closest to the MEC server serving the user. Since the MEC server usually sinks to the edge of the mobile network, the actual topological location of the MEC server may be far away from the local DNS server. If the traditional CDN node allocation method is adopted, the CDN global load balancer still selects the CDN node for the user according to the IP address of the local DNS server, and cannot effectively select the appropriate distance for the user under this framework. The topology of the MEC server serving the user Closer CDN nodes

Abstract

Embodiments of the present invention provide a method and system for allocating CDN nodes based on MEC, which relate to the communication field and are used for allocating CDN nodes with smaller delays to users under the MEC framework. The method includes: the MEC server receives the DNS request sent by the user terminal and sends it and the identifier of the nearest CDN node to the CDN global load balancer; the CDN global load balancer obtains the distance according to the identifier of the nearest CDN node and the pre-stored CDN node topology information The ID of the closest CDN node, and then select the best CDN node according to the topological distance between the target CDN node and the nearest CDN node and the load rate of each pre-stored CDN node, and send the ID of the best CDN node to the MEC server so that it will The pre-stored network protocol IP address corresponding to the identifier of the best CDN node is sent to the user terminal; the target CDN node includes the nearest CDN node and the closest CDN node.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for allocating CDN nodes based on MEC. Background technique [0002] CDN (Content Delivery Network, content distribution network) technology refers to the placement of node servers throughout the network, thereby forming a layer of intelligent virtual network architecture on the basis of the existing Internet. Through CDN technology, the content of the website can be released to the network "edge" closest to the user, so that the user can obtain the required content nearby, thereby improving the response speed of the user's access to the website and improving the user experience. In traditional CDN technology, the allocation scheme of node servers is mainly realized through dynamic DNS technology. In the dynamic DNS technology, it assumes that the user client and the local DNS (Domain Name System, Domain Name System) server used by the user are in the same a...
