A novel traffic shaping algorithm with delay jitter constraints for real-time multimedia networks

摘要

Data traversing packet networks experience varying delays, resulting in noticeable delay jitters. This significantly degrades overall system performance in a real-time multimedia network. This paper proposes TSJC, a novel traffic shaping algorithm with delay jitter constraints for real-time multimedia networks, on the basis of traditional shaping algorithms and their traffic characteristics. TSJC computes the queuing delay and queuing delay variation on line by monitoring the token bucket states, such as the queue length and token arrival rate. TSJC adaptively configures system parameters based on the queuing delay and time jitter, to provide universally low jitter outputs. Simulations have shown that TSJC can both smooth traffic fluctuation and decrease the delay jitter.
