Abstract: A method and a user terminal for establishing a connection between the user terminal and a content server are provided. The method includes receiving, at the user terminal, a domain name server (DNS) response including addresses of a plurality of content delivery network (CDN) servers, detecting a round trip time (RTT) for each of the plurality of the CDN servers based on the address of each of the plurality of the CDN servers, the RTT being a time length for rounding trip from the user terminal via one of the CDN servers to the user terminal, determining a first CDN server based on the lowest RTT, transmitting a request for content to the first CDN server, and receiving the requested content from the first CDN server.
