Abstract :
Content delivery networks have emerged to conquer massive requests problem in popular web services. One of the major issues in CDNs is the replica server placement problem. If the replica servers are geographically closer to the users, overall bandwidth consumption and the users´ perceived latency will be reduced significantly. In this paper we have used IP geolocation services to achieve the users´ locations in terms of latitude and longitude. Then we have clustered users according to their coordinates. Locating servers around the cluster centers, provides better performance of CDN.
