Buffer management strategies in various networks have been extensively studied in the literature. However, little work has considered the condition in which the traffic exhibits inter-packet dependency, a common occurrence with many applications. This paper concentrates on the goodput maximization problem for streaming data with packet dependencies. A novel optimization model is put forward to describe the aforementioned problem and a goodput guaranteed buffer management (GGBM) algorithm is proposed to achieve the optimal solution to the problem. By replacing the bounded buffers with dynamically managed chained buffering, the GGBM algorithm effectively avoids overflows which can lead to degradation of goodput. Simulation results demonstrate that the GGBM algorithm can indeed obtain the optimal goodput ratio in practice. In addition, the GGBM algorithm outperforms the well-known buffer management (WKBM) algorithm as it increase the buffer utilization ratio by more than 45%.
