Abstract
A method of request routing redirection includes: receiving, by a first content delivery network (CDN) among a plurality of CDNs connected by CDN interconnection (CDNi), a domain name system (DNS) request including a list of CDN-provider-identifications (IDs) of higher CDNs, from a client; determining whether the client's request is processable; and when the client's request is not processable, redirecting the request, while preventing a loop of the request routing on the basis of the list of the CDN-provider-IDs.
