Explanation:
With the CRA answer, requests received from a particular D-proxy are served by the content server that responds first to the request. Response time is measured using a DNS race, coordinated by the GSS and content routing agents running on each content server. In the DNS race, multiple hosts respond simultaneously to an A-record request. The server with the fastest response time (the shortest network delay between itself and the client’s Dproxy) is chosen to serve the content.
