CDN node emergency processing method and system for source station fault

Abstract

The invention provides a CDN node emergency processing method and system for a source station fault, and the method comprises the steps: receiving an access request transmitted by a terminal through aCDN node, and determining a resource type obtained by the access request; when the resource type is a dynamic resource, if the source station is normal, sending a dynamic resource access request to the source station to obtain the corresponding dynamic resource; and if the source station fails, returning a pre-stored static control to the terminal to enable the terminal to display a basic page toa user. The invention can provide an automatic detection takeover and recovery strategy of the CDN node when the source station fails, effectively control the service influence range and improve thecustomer experience.

[0002] With the continuous development and growth of the Internet financial business, in order to meet the needs of customers in different scenarios, the front-end applications that provide services to customers have been continuously enriched, and the volume of front-end sites has increased sharply. In order to alleviate the pressure on the origin site, our bank introduced CDN nodes for architecture optimization. Cache static resources to CDN nodes, but the current "CDN-origin site" deployment architecture does not have a strong application relationship linkage. CDN can only be used as a cache node, which is heavily dependent on the source site, and cannot be used in extreme scenarios. Site emergency takeover function, when the source site is abnormal, manual intervention is required to switch CDN nodes

With the Internet server architecture transformation and version iteration of financial institutions getting faster and faster, equipment, systems, networks, and applications are constantly facing development and changes. Mistakes in production strategies and manual operations will all bring extreme pressure to the stable operation of production. Large risks and hidden dangers, the complexity of the application environment put forward higher emergency skills requirements for the production and maintenance department, manual operation requires high technical requirements for front-line technicians and seriously affects emergency efficiency
