Deterministic traffic regulation with decoder buffer constraints for streaming videos

Due to the burstiness property of compressed videos, an effective video traffic description scheme is important for efficient network bandwidth management. This paper proposes an elastically deterministic video traffic regulating mechanism (ED-VTR) that models and regulates the video traffic based on constraints of available decoder buffer space. In contrast to traditional methods, ED-VTR generates a transmission schedule that contains a series of monotonically decreasing bandwidth requests. Simulation results show that, using lower initial bandwidth and smaller decoder buffer requirement, ED-VTR can effectively reduce the complexity of bandwidth management and still hold the advantages of traditional traffic smoothing and deterministic traffic modeling methods.
