Abstract :
This paper presents two novel cloning schemes for video delivery in Optical Burst Switching Networks. These schemes take into account the special characteristics of compressed video traffic and dramatically improve received video quality. Analytical and simulation results show up to 40% quality improvement without a substantial increase in the overall network traffic. The results show the strong dependency of these novel cloning schemes on the video traffic structure due to the coding mechanisms. Rules based on the GoP structure are presented to decide the frames to clone.
