Abstract

The embodiment of the invention discloses a CDN node selection method and equipment, relates to the communication field, and realizes the selection of a CDN node with strong service capability from edge CDN nodes and external CDN nodes. The specific solution is: the MEC server receives the DNS request sent by the terminal, sends the DNS request to the load balancer, receives the IP address of the target external CDN node and the first service delay sent by the load balancer, and determines each of the at least one edge CDN node The service delay of the edge CDN node, and determine the minimum service delay as the second service delay, according to the IP address of the target external CDN node, determine the transmission delay, according to the second service delay, and the first service delay The target CDN node is determined based on the comparison result with the sum of transmission delays, and the IP address of the target CDN node is sent to the terminal. The embodiment of the present invention is used in the process of selecting a CDN node for a terminal.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a method and device for selecting a content delivery network (Content Delivery Network, CDN) node. Background technique [0002] With the development of mobile Internet services and network technologies, a mobile edge computing (Mobile Edge Computing, MEC) architecture began to emerge. The MEC architecture can be used to provide mobile network services. When providing CDN services, the CDN node can be selected through the MEC architecture so that the terminal can obtain the required content nearby, and the selection of the CDN node can be done through the domain name service (Domain Name Service, DNS ) technology to achieve. [0003] The selection process of the CDN node in the prior art is as follows: After receiving the DNS request sent by the terminal, the MEC server can select a node closest to the terminal from among the multiple connected edge CDN nodes...
