document: Packet spacing : an enabling mechanism for delivering multimedia content in computational grids Streaming multimedia with UDP has become increasingly popular over distributed systems like the Internet . Scientific applications that stream multimedia include remote computational steering of visualization data and video-on-demand teleconferencing over the Access Grid . However , UDP does not possess a self-regulating , congestion-control mechanism ; and most best-effort traffic is served by congestion-controlled TCP . Consequently , UDP steals bandwidth from TCP such that TCP flows starve for network resources . With the volume of Internet traffic continuing to increase , the perpetuation of UDP-based streaming will cause the Internet to collapse as it did in the mid-1980 's due to the use of non-congestion-controlled TCP . To address this problem , we introduce the counter-intuitive notion of inter-packet spacing with control feedback to enable UDP-based applications to perform well in the next-generation Internet and computational grids . When compared with traditional UDP-based streaming , we illustrate that our approach can reduce packet loss over 50 % without adversely affecting delivered throughput
