document: Measurement and analysis of cyberlocker services Cyberlocker Services ( CLS ) such as RapidShare and Megaupload have recently become popular . The decline of Peer-to-Peer ( P2P ) file sharing has prompted various services including CLS to replace it . We propose a comprehensive multi-level characterization of the CLS ecosystem . We answer three research questions : ( a ) what is a suitable measurement infrastructure for gathering CLS workloads ; ( b ) what are the characteristics of the CLS ecosystem ; and ( c ) what are the implications of CLS on Web 2.0 ( and the Internet ) . To the best of our knowledge , this work is the first to characterize the CLS ecosystem . The work will highlight the content , usage , performance , infrastructure , quality of service , and evolution characteristics of CLS .
