ISPs (120-1-120-n) comprise a backbone network (130) and a plurality of networks (140-1-140-n) connected through the backbone network. The networks provide the internet connectivity to a user device (170) and includes a plurality of contents delivery network (CDN) servers (151,152,153) and a service request routing system (160). The CDN servers (151,152,153) store contents supplied by the contents provider through the backbone network, receive the request, and deliver a corresponding content segment to the user device. The service request routing system stores routing information including position information of the CDN server in which the content segment is stored, and provides an IP address and content segment information of the CDN server according to the request from the user device.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Content business carrier; (130) Backbone network; (140-1) Access network 1; (140-n) Access network n; (160,AA) Service request routing system; (170,BB) User device
