document: Analysis of multimedia workloads with implications for internet streaming In this paper , we study the media workload collected from a large number of commercial Web sites hosted by a major ISP and that collected from a large group of home users connected to the Internet via a well-known cable company . Some of our key findings are : ( 1 ) Surprisingly , the majority of media contents are still delivered via downloading from Web servers . ( 2 ) A substantial percentage of media downloading connections are aborted before completion due to the long waiting time . ( 3 ) A hybrid approach , pseudo streaming , is used by clients to imitate real streaming . ( 4 ) The mismatch between the downloading rate and the client playback speed in pseudo streaming is common , which either causes frequent playback delays to the clients , or unnecessary traffic to the Internet . ( 5 ) Compared with streaming , downloading and pseudo streaming are neither bandwidth efficient nor performance effective . To address this problem , we propose the design of AutoStream , an innovative system that can provide additional previewing and streaming services automatically for media objects hosted on standard Web sites in server farms at the client 's will .
